The gas then glows infrared light in what is known as a thermal light echo. As the supernova illumination travels through space at the speed of light, the echo appears to expand. NASA’s James Webb Space Telescope observed this light echo in the vicinity of the supernova remnant Cassiopeia A. Credits: NASA, ESA, CSA, STScI, J. Jencson (Caltech/IPAC) Once upon a time, the core of a massive star collapsed, creating a shockwave that blasted outward, ripping the star apart as it went. When the shockwave reached the star’s surface, it punched through, generating a brief, intense pulse of X-rays and ultraviolet light that traveled outward into the surrounding space. About 350 years later, that pulse of light has reached interstellar material, illuminating it, warming it, and causing it to glow in infrared light. NASA’s James Webb Space Telescope has observed that infrared glow, revealing fine details resembling the knots and whorls of wood grain. These observations are allowing astronomers to map the true 3D structure of this interstellar dust and gas (known as the interstellar medium) for the first time. “We were pretty shocked to see this level of detail,” said Jacob Jencson of Caltech/IPAC in Pasadena, principal investigator of the science program. “We see layers like an onion,” added Josh Peek of the Space Telescope Science Institute in Baltimore, a member of the science team. “We think every dense, dusty region that we see, and most of the ones we don’t see, look like this on the inside. We just have never been able to look inside them before.” The team is presenting their findings in a press conference at the 245th meeting of the American Astronomical Society in Washington. “Even as a star dies, its light endures—echoing across the cosmos. It’s been an extraordinary three years since we launched NASA’s James Webb Space Telescope. Every image, every discovery, shows a portrait not only of the majesty of the universe but the power of the NASA team and the promise of international partnerships. This groundbreaking mission, NASA’s largest international space science collaboration, is a true testament to NASA’s ingenuity, teamwork, and pursuit of excellence,” said NASA Administrator Bill Nelson. “What a privilege it has been to oversee this monumental effort, shaped by the tireless dedication of thousands of scientists and engineers around the globe. This latest image beautifully captures the lasting legacy of Webb—a keyhole into the past and a mission that will inspire generations to come.” Image A: Light Echoes Near Cassiopeia A (NIRCam) These shimmering cosmic curtains show interstellar gas and dust that has been heated by the flashbulb explosion of a long-ago supernova. The gas then glows infrared light in what is known as a thermal light echo. As the supernova illumination travels through space at the speed of light, the echo appears to expand. NASA’s James Webb Space Telescope observed this light echo in the vicinity of the supernova remnant Cassiopeia A three separate times, in essence creating a 3D scan of the interstellar material. Note that the field of view in the top row is rotated slightly clockwise relative to the middle and bottom rows, due to the roll angle of the Webb telescope when the observations were taken. NASA, ESA, CSA, STScI, J. Jencson (Caltech/IPAC) Video A: Light Echoes Near Cassiopeia A (NIRCam) This time-lapse video using data from NASA’s James Webb Space Telescope highlights the evolution of one light echo in the vicinity of the supernova remnant Cassiopeia A. A light echo is created when a star explodes or erupts, flashing light into surrounding clumps of interstellar dust and causing them to shine in an ever-expanding pattern. Webb’s exquisite resolution not only shows incredible detail within these light echoes, but also shows their expansion over the course of just a few weeks – a remarkably short timescale considering that most cosmic targets remain unchanged over a human lifetime. Credit: NASA, ESA, CSA, STScI, J. Jencson (Caltech/IPAC) Taking a CT Scan The images from Webb’s NIRCam (Near-Infrared Camera) highlight a phenomenon known as a light echo. A light echo is created when a star explodes or erupts, flashing light into surrounding clumps of dust and causing them to shine in an ever-expanding pattern. Light echoes at visible wavelengths (such as those seen around the star V838 Monocerotis) are due to light reflecting off of interstellar material. In contrast, light echoes at infrared wavelengths are caused when the dust is warmed by energetic radiation and then glows. The researchers targeted a light echo that had previously been observed by NASA’s retired Spitzer Space Telescope. It is one of dozens of light echoes seen near the Cassiopeia A supernova remnant – the remains of the star that exploded. The light echo is coming from unrelated material that is behind Cassiopeia A, not material that was ejected when the star exploded. The most obvious features in the Webb images are tightly packed sheets. These filaments show structures on remarkably small scales of about 400 astronomical units, or less than one-hundredth of a light-year. (An astronomical unit, or AU, is the average Earth-Sun distance. Neptune’s orbit is 60 AU in diameter.) “We did not know that the interstellar medium had structures on that small of a scale, let alone that it was sheet-like,” said Peek. These sheet-like structures may be influenced by interstellar magnetic fields. The images also show dense, tightly wound regions that resemble knots in wood grain. These may represent magnetic “islands” embedded within the more streamlined magnetic fields that suffuse the interstellar medium. “This is the astronomical equivalent of a medical CT scan,” explained Armin Rest of the Space Telescope Science Institute, a member of the science team. “We have three slices taken at three different times, which will allow us to study the true 3D structure. It will completely change the way we study the interstellar medium.” Image B: Cassiopeia A (Spitzer with Webb Insets) This background image of the region around supernova remnant Cassiopeia A was released by NASA’s Spitzer Space Telescope in 2008. By taking multiple images of this region over three years with Spitzer, researchers were able to examine a number of light echoes. Now, NASA’s James Webb Space Telescope has imaged some of these light echoes in much greater detail. Insets at lower right show one epoch of Webb observations, while the inset at left shows a Webb image of the central supernova remnant released in 2023. Spitzer Image: NASA/JPL-Caltech/Y.

Light Echoes Inset: NASA, ESA, CSA, STScI, J. Jencson (Caltech/IPAC). Future Work The team’s science program also includes spectroscopic observations using Webb’s MIRI (Mid-Infrared Instrument). They plan to target the light echo multiple times, weeks or months apart, to observe how it evolves as the light echo passes by. “We can observe the same patch of dust before, during, and after it’s illuminated by the echo and try to look for any changes in the compositions or states of the molecules, including whether some molecules or even the smallest dust grains are destroyed,” said Jencson. Infrared light echoes are also extremely rare, since they require a specific type of supernova explosion with a short pulse of energetic radiation. NASA’s upcoming Nancy Grace Roman Space Telescope will conduct a survey of the galactic plane that may find evidence of additional infrared light echoes for Webb to study in detail. The James Webb Space Telescope is the world’s premier space science observatory. Webb is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and CSA (Canadian Space Agency).

Firefly Aerospace’s Blue Ghost lander getting encapsulated in SpaceX’s rocket fairing ahead of the planned liftoff for 1:11 a.m. EST Jan. 15 from Launch Complex 39A at NASA’s Kennedy Space Center in FloridaSpaceX As part of NASA’s CLPS (Commercial Lunar Payload Services) initiative and Artemis campaign, the agency is preparing to fly ten instruments aboard Firefly Aerospace’s first delivery to the Moon. These science payloads and technology demonstrations will help advance our understanding of the Moon and planetary processes, while paving the way for future crewed missions on the Moon and beyond, for the benefit of all. Firefly’s lunar lander, named Blue Ghost, is scheduled to launch on a SpaceX Falcon 9 rocket Wednesday, Jan.15, from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. After a 45-day cruise phase, Blue Ghost is targeted to land near a volcanic feature called Mons Latreille within Mare Crisium, a basin approximately 340 miles wide (550 kilometers) located in the northeast quadrant of the Moon’s near side. How can we enable more precise navigation on the Moon? How do spacecraft interact with the lunar surface? How does Earth’s magnetic field influence the effects of space weather on our home planet? NASA’s instruments on this flight will conduct first-of-their-kind demonstrations to help answer these questions and more, including testing regolith sampling technologies, lunar subsurface drilling capabilities, increasing precision of positioning and navigation abilities, testing radiation tolerant computing, and learning how to mitigate lunar dust during lunar landings. The ten NASA payloads aboard Firefly’s Blue Ghost lander include: Lunar Instrumentation for Subsurface Thermal Exploration with Rapidity (LISTER) will measure heat flow from the Moon’s interior by measuring the thermal gradient, or changes in temperature at various depths, and thermal conductivity, or the subsurface material’s ability to let heat pass through it. LISTER will take several measurements up to 10 feet deep using pneumatic drilling technology with a custom heat flow needle instrument at its tip. Data from LISTER will help scientists retrace the Moon’s thermal history and understand how it formed and cooled. Lead organization: Texas Tech University Lunar PlanetVac (LPV) is designed to collect regolith samples from the lunar surface using a burst of compressed gas to drive the regolith into a sample chamber (sieving) for collection and analysis by various instruments. Additional instrumentation will then transmit the results back to Earth. The LPV payload is designed to help increase the science return from planetary missions by testing low-cost technologies for collecting regolith samples in-situ. Lead organization: Honeybee Robotics Next Generation Lunar Retroreflector (NGLR) serves as a target for lasers on Earth to precisely measure the distance between Earth and the Moon by reflecting very short laser pulses from Earth-based Lunar Laser Ranging Observatories. The laser pulse transit time to the Moon and back is used to determine the distance. Data from NGLR could improve the accuracy of our lunar coordinate system and contribute to our understanding of the inner structure of the Moon and fundamental physics questions. Lead organization: University of Maryland Regolith Adherence Characterization (RAC) will determine how lunar regolith sticks to a range of materials exposed to the Moon’s environment throughout the lunar day. RAC will measure accumulation rates of lunar regolith on surfaces (for example, solar cells, optical systems, coatings, and sensors) through imaging to determine their ability to repel or shed lunar dust. The data captured will help test, improve, and protect spacecraft, spacesuits, and habitats from abrasive regolith. Lead organization: Aegis Aerospace Radiation Tolerant Computer (RadPC) will demonstrate a computer that can recover from faults caused by ionizing radiation. Several RadPC prototypes have been tested aboard the International Space Station and Earth-orbiting satellites, but this flight will provide the biggest trial yet by demonstrating the computer’s ability to withstand space radiation as it passes through Earth’s radiation belts, while in transit to the Moon, and on the lunar surface. Lead organization: Montana State University Electrodynamic Dust Shield (EDS) is an active dust mitigation technology that uses electric fields to move and prevent hazardous lunar dust accumulation on surfaces. EDS is designed to lift, transport, and remove particles from surfaces with no moving parts. Multiple tests will demonstrate the feasibility of the self-cleaning glasses and thermal radiator surfaces on the Moon. In the event the surfaces do not receive dust during landing, EDS has the capability to re-dust itself using the same technology. Lead organization: NASA’s Kennedy Space Center Lunar Environment heliospheric X-ray Imager (LEXI) will capture a series of X-ray images to study the interaction of solar wind and Earth’s magnetic field that drives geomagnetic disturbances and storms. Deployed and operated on the lunar surface, this instrument will provide the first global images showing the edge of Earth’s magnetic field for critical insights into how space weather and other cosmic forces surrounding our planet impact Earth. Lead organizations: Boston University, NASA’s Goddard Space Flight Center, and Johns Hopkins University Lunar Magnetotelluric Sounder (LMS) will characterize the structure and composition of the Moon’s mantle by measuring electric and magnetic fields. This investigation will help determine the Moon’s temperature structure and thermal evolution to understand how the Moon has cooled and chemically differentiated since it formed. Lead organization: Southwest Research Institute Lunar GNSS Receiver Experiment (LuGRE) will demonstrate the possibility of acquiring and tracking signals from GNSS (Global Navigation Satellite System) constellations, specifically GPS and Galileo, during transit to the Moon, during lunar orbit, and on the lunar surface. If successful, LuGRE will be the first pathfinder for future lunar spacecraft to use existing Earth-based navigation constellations to autonomously and accurately estimate their position, velocity, and time. Lead organizations: NASA Goddard, Italian Space Agency Stereo Camera for Lunar Plume-Surface Studies (SCALPSS) will use stereo imaging photogrammetry to capture the impact of the rocket exhaust plume on lunar regolith as the lander descends on the Moon’s surface. The high-resolution stereo images will aid in creating models to predict lunar regolith erosion, which is an important task as bigger, heavier spacecraft and hardware are delivered to the Moon in close proximity to each other. This instrument also flew on Intuitive Machines’ first CLPS delivery. Lead organization: NASA’s Langley Research Center Through the CLPS initiative, NASA purchases lunar landing and surface operations services from American companies. The agency uses CLPS to send scientific instruments and technology demonstrations to advance capabilities for science, exploration, or commercial development of the Moon. By supporting a robust cadence of lunar deliveries, NASA will continue to enable a growing lunar economy while leveraging the entrepreneurial innovation of the commercial space industry.

Astronomers have released a set of more than a million simulated images showcasing the cosmos as NASA’s upcoming Nancy Grace Roman Space Telescope will see it. This preview will help scientists explore a myriad of Roman’s science goals. “We used a supercomputer to create a synthetic universe and simulated billions of years of evolution, tracing every photon’s path all the way from each cosmic object to Roman’s detectors,” said Michael Troxel, an associate professor of physics at Duke University in Durham, North Carolina, who led the simulation campaign. “This is the largest, deepest, most realistic synthetic survey of a mock universe available today.” To view this video please enable JavaScript, and consider upgrading to a web browser that supports HTML5 video This video begins with a tiny one-square-degree portion of the full OpenUniverse simulation area (about 70 square degrees, equivalent to an area of sky covered by more than 300 full moons). It spirals in toward a particularly galaxy-dense region, zooming by a factor of 75. This simulation showcases the cosmos as NASA’s Nancy Grace Roman Space Telescope could see it, allowing scientists to preview the next generation of cosmic discovery now. Roman’s real future surveys will enable a deep dive into the universe with highly resolved imaging, as demonstrated in this video. NASA’s Goddard Space Flight Center and M. Troxel The project, called OpenUniverse, relied on the now-retired Theta supercomputer at the DOE’s (Department of Energy’s) Argonne National Laboratory in Illinois. The supercomputer accomplished a process that would take over 6,000 years on a typical computer in just nine days. In addition to Roman, the 400-terabyte dataset will also preview observations from the Vera C. Rubin Observatory, which is jointly funded by the National Science Foundation and the U.S. Department of Energy, and approximate simulations from ESA’s (the European Space Agency’s) Euclid mission, which has NASA contributions. The Roman data is available now here, and the Rubin and Euclid data will soon follow. The team used the most sophisticated modeling of the universe’s underlying physics available and fed in information from existing galaxy catalogs and the performance of the telescopes’ instruments. The resulting simulated images span 70 square degrees, equivalent to an area of sky covered by more than 300 full moons. In addition to covering a broad area, it also covers a large span of time — more than 12 billion years. Each tiny dot in the image at left is a galaxy simulated by the OpenUniverse campaign. The one-square-degree image offers a small window into the full simulation area, which is about 70 square degrees (equivalent to an area of sky covered by more than 300 full moons), while the inset at right is a close-up of an area 75 times smaller (1/600th the size of the full area). This simulation showcases the cosmos as NASA’s Nancy Grace Roman Space Telescope could see it. Roman will expand on the largest space-based galaxy survey like it – the Hubble Space Telescope’s COSMOS survey – which imaged two square degrees of sky over the course of 42 days. In only 250 days, Roman will view more than a thousand times more of the sky with the same resolution. The project’s immense space-time coverage shows scientists how the telescopes will help them explore some of the biggest cosmic mysteries. They will be able to study how dark energy (the mysterious force thought to be accelerating the universe’s expansion) and dark matter (invisible matter, seen only through its gravitational influence on regular matter) shape the cosmos and affect its fate. Scientists will get closer to understanding dark matter by studying its gravitational effects on visible matter. And by studying the simulation’s 100 million synthetic galaxies, they will see how galaxies and galaxy clusters evolved over eons. Repeated mock observations of a particular slice of the universe enabled the team to stitch together movies that unveil exploding stars crackling across the synthetic cosmos like fireworks. These starbursts allow scientists to map the expansion of the simulated universe. This simulation showcases the dynamic universe as NASA’s Nancy Grace Roman Space Telescope could see it over the course of its five-year primary mission. The video sparkles with synthetic supernovae from observations of the OpenUniverse simulated universe taken every five days (similar to the expected cadence of Roman’s High-Latitude Time-Domain Survey, which OpenUniverse simulates in its entirety). On top of the static sky of stars in the Milky Way and other galaxies, more than a million exploding stars flare into visibility and then slowly fade away. To highlight the dynamic physics happening and for visibility at this scale, the true brightness of each transient event has been magnified by a factor of 10,000 and no background light has been added to the simulated images. The video begins with Roman’s full field of view, which represents a single pointing of Roman’s camera, and then zooms into one square.NASA’s Goddard Space Flight Center and M. Troxel Scientists are now using OpenUniverse data as a testbed for creating an alert system to notify astronomers when Roman sees such phenomena. The system will flag these events and track the light they generate so astronomers can study them. That’s critical because Roman will send back far too much data for scientists to comb through themselves. Teams are developing machine-learning algorithms to determine how best to filter through all the data to find and differentiate cosmic phenomena, like various types of exploding stars. “Most of the difficulty is in figuring out whether what you saw was a special type of supernova that we can use to map how the universe is expanding, or something that is almost identical but useless for that goal,” said Alina Kiessling, a research scientist at NASA’s Jet Propulsion Laboratory (JPL) in Southern California and the principal investigator of OpenUniverse. While Euclid is already actively scanning the cosmos, Rubin is set to begin operations late this year and Roman will launch by May 2027. Scientists can use the synthetic images to plan the upcoming telescopes’ observations and prepare to handle their data. This prep time is crucial because of the flood of data these telescopes will provide. In terms of data volume, “Roman is going to blow away everything that’s been done from space in infrared and optical wavelengths before,” Troxel said. “For one of Roman’s surveys, it will take less than a year to do observations that would take the Hubble or James Webb space telescopes around a thousand years. The sheer number of objects Roman will sharply image will be transformative.” This synthetic OpenUniverse animation shows the type of science that astronomers will be able to do with future Roman deep-field observations. The gravity of intervening galaxy clusters and dark matter can lens the light from farther objects, warping their appearance as shown in the animation. By studying the distorted light, astronomers can study elusive dark matter, which can only be measured indirectly through its gravitational effects on visible matter. As a bonus, this lensing also makes it easier to see the most distant galaxies whose light the dark matter magnifies. Caltech-IPAC/R. Hurt “We can expect an incredible array of exciting, potentially Nobel Prize-winning science to stem from Roman’s observations,” Kiessling said. “The mission will do things like unveil how the universe expanded over time, make 3D maps of galaxies and galaxy clusters, reveal new details about star formation and evolution — all things we simulated. So now we get to practice on the synthetic data so we can get right to the science when real observations begin.” Astronomers will continue using the simulations after Roman launches for a cosmic game of spot the differences. Comparing real observations with synthetic ones will help scientists see how accurately their simulation predicts reality. Any discrepancies could hint at different physics at play in the universe than expected. “If we see something that doesn’t quite agree with the standard model of cosmology, it will be extremely important to confirm that we’re really seeing new physics and not just misunderstanding something in the data,” said Katrin Heitmann, a cosmologist and deputy director of Argonne’s High Energy Physics division who managed the project’s supercomputer time. “Simulations are super useful for figuring that out.” OpenUniverse, along with other simulation tools being developed by Roman’s Science Operations and Science Support centers, will prepare astronomers for the large datasets expected from Roman. The project brings together dozens of experts from NASA’s JPL, DOE’s Argonne, IPAC, and several U.S. universities to coordinate with the Roman Project Infrastructure Teams, SLAC, and the Rubin LSST DESC (Legacy Survey of Space and Time Dark Energy Science Collaboration). The Theta supercomputer was operated by the Argonne Leadership Computing Facility, a DOE Office of Science user facility. The Nancy Grace Roman Space Telescope is managed at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, with participation by NASA’s Jet Propulsion Laboratory and Caltech/IPAC in Southern California, the Space Telescope Science Institute in Baltimore, and a science team comprising scientists from various research institutions.

Credits: NASA, ESA, CSA, STScI, Dale Kocevski (Colby College). In December 2022, less than six months after commencing science operations, NASA’s James Webb Space Telescope revealed something never seen before: numerous red objects that appear small on the sky, which scientists soon called “little red dots” (LRDs). Though these dots are quite abundant, researchers are perplexed by their nature, the reason for their unique colors, and what they convey about the early universe. A team of astronomers recently compiled one of the largest samples of LRDs to date, nearly all of which existed during the first 1.5 billion years after the big bang. They found that a large fraction of the LRDs in their sample showed signs of containing growing supermassive black holes. “We’re confounded by this new population of objects that Webb has found. We don’t see analogs of them at lower redshifts, which is why we haven’t seen them prior to Webb,” said Dale Kocevski of Colby College in Waterville, Maine, and lead author of the study. “There’s a substantial amount of work being done to try to determine the nature of these little red dots and whether their light is dominated by accreting black holes.” Image A: Little Red Dots (NIRCam Image) A team of astronomers sifted through James Webb Space Telescope data from multiple surveys to compile one of the largest samples of “little red dots” to date. From their sample, they found that these mysterious red objects that appear small on the sky emerge in large numbers around 600 million years after the big bang and undergo a rapid decline in quantity around 1.5 billion years after the big bang. NASA, ESA, CSA, STScI, Dale Kocevski (Colby College). A Potential Peek Into Early Black Hole Growth A significant contributing factor to the team’s large sample size of LRDs was their use of publicly available Webb data. To start, the team searched for these red sources in the Cosmic Evolution Early Release Science (CEERS) survey before widening their scope to other extragalactic legacy fields, including the JWST Advanced Deep Extragalactic Survey (JADES) and the Next Generation Deep Extragalactic Exploratory Public (NGDEEP) survey. The methodology used to identify these objects also differed from previous studies, resulting in the census spanning a wide redshift range. The distribution they discovered is intriguing: LRDs emerge in large numbers around 600 million years after the big bang and undergo a rapid decline in quantity around 1.5 billion years after the big bang. The team looked toward the Red Unknowns: Bright Infrared Extragalactic Survey (RUBIES) for spectroscopic data on some of the LRDs in their sample. They found that about 70 percent of the targets showed evidence for gas rapidly orbiting 2 million miles per hour (1,000 kilometers per second) – a sign of an accretion disk around a supermassive black hole. This suggests that many LRDs are accreting black holes, also known as active galactic nuclei (AGN). “The most exciting thing for me is the redshift distributions. These really red, high-redshift sources basically stop existing at a certain point after the big bang,” said Steven Finkelstein, a co-author of the study at the University of Texas at Austin. “If they are growing black holes, and we think at least 70 percent of them are, this hints at an era of obscured black hole growth in the early universe.” Contrary to Headlines, Cosmology Isn’t Broken When LRDs were first discovered, some suggested that cosmology was “broken.” If all of the light coming from these objects was from stars, it implied that some galaxies had grown so big, so fast, that theories could not account for them. The team’s research supports the argument that much of the light coming from these objects is from accreting black holes and not from stars. Fewer stars means smaller, more lightweight galaxies that can be understood by existing theories. “This is how you solve the universe-breaking problem,” said Anthony Taylor, a co-author of the study at the University of Texas at Austin. Curiouser and Curiouser There is still a lot up for debate as LRDs seem to evoke even more questions. For example, it is still an open question as to why LRDs do not appear at lower redshifts. One possible answer is inside-out growth: As star formation within a galaxy expands outward from the nucleus, less gas is being deposited by supernovas near the accreting black hole, and it becomes less obscured. In this case, the black hole sheds its gas cocoon, becomes bluer and less red, and loses its LRD status. Additionally, LRDs are not bright in X-ray light, which contrasts with most black holes at lower redshifts. However, astronomers know that at certain gas densities, X-ray photons can become trapped, reducing the amount of X-ray emission. Therefore, this quality of LRDs could support the theory that these are heavily obscured black holes. The team is taking multiple approaches to understand the nature of LRDs, including examining the mid-infrared properties of their sample, and looking broadly for accreting black holes to see how many fit LRD criteria. Obtaining deeper spectroscopy and select follow-up observations will also be beneficial for solving this currently “open case” about LRDs. “There’s always two or more potential ways to explain the confounding properties of little red dots,” said Kocevski. “It’s a continuous exchange between models and observations, finding a balance between what aligns well between the two and what conflicts.” These results were presented in a press conference at the 245th meeting of the American Astronomical Society in National Harbor, Maryland, and have been submitted for publication in The Astrophysical Journal.

Learn Home NASA HEAT Student Activity… Heliophysics Overview Learning Resources Science Activation Teams SME Map Opportunities More Science Activation Stories Citizen Science 3 min read NASA HEAT Student Activity Featured in TIME’s Top 100 Photos of 2024 On April 8, 2024, tens of millions experienced a solar eclipse from Mexico through the United States and into Canada. Astronomers, educators, and organizations had been preparing the public for this grand celestial event. Learning from engagement experiences in 2017, the NASA Heliophysics Education Activation Team (NASA HEAT) promoted an activity called “Eclipse Essentials: Safe and Stylish Solar Viewing Glasses.” The activity was first tested in Albuquerque, New Mexico during the Balloon Fiesta around the October 2023 annular eclipse. Using solar viewing glasses, a paper plate, some drawing and decoration supplies, visitors – minors and adults alike – crowded around the heliophysics tables in the NASA tent. That positive experience led NASA HEAT to modify and perfect the design of their “face shield” activity before offering trainings to numerous educators and outreach personnel in the weeks leading up to the April 2024 engagement events. Note: The glasses and the art activity are not only useful for solar eclipses. They can be used anytime to safely observe the Sun. While it is never safe to look directly at the sun with unprotected eyes, eclipse glasses are perfect for observing sunspots! One proof of positive impact can be found at the Myers Elementary School in Grand Blanc, Michigan. Students from two kindergarten classes, escorted outside by their teachers Amy Johnston and Wendy Sheridan, stared toward the sky with their solar viewing glasses using paper plates to watch the solar eclipse on Monday, April 8, 2024. The paper plates, which helped provide additional safety measures to protect their eyes, were attached to solar eclipse glasses and decorated by each student in their classrooms as a project leading up to the big day. A photo of the students was so captivating that multiple media outlets shared it on or shortly after the day of the eclipse. The global media brand, TIME, selected a photo of these kindergarten students wearing their NASA HEAT-designed solar eclipse-viewing “face shields” during the April 8th solar eclipse as one of “TIME’s Top 100 Photos of 2024”. When sharing about the top 100 photos on Instagram, TIME had this to say: “Every year the TIME photo department sits down to curate the strongest images that crossed our path over the previous 12 months. And every year, sitting with the images, we find ourselves mulling the ways this collection feels heavier than the last, how the year produced images unlike what we’ve seen before. But this year something else, a tautness, runs through the collection – the tension of conflict, the anxiety over outcome, anticipation of excitement or in possibility. Somehow, these photographers are able to capture that coiled feeling and hold it within the four walls of a frame. Be it by impeccable timing or intentional framing, they have created a time capsule that feels as if it’s about to be opened.” NASA HEAT is part of NASA’s Science Activation Portfolio.

NASA On April 21, 1972, NASA astronaut John W. Young, commander of the Apollo 16 mission, took a far-ultraviolet photo of Earth with an ultraviolet camera. Young’s original black-and-white picture was printed on Agfacontour professional film three times, with each exposure recording only one light level. The three light levels were then colored blue (dimmest), green (next brightest), and red (brightest), resulting in the enhanced-color image seen here. Dr. George Carruthers, a scientist at the Naval Research Laboratory, developed the ultraviolet camera – the first Moon-based observatory – for Apollo 16. Apollo 16 astronauts placed the observatory on the Moon in April 1972, where it sits today on the Moon’s Descartes highland region, in the shadow of the lunar module Orion.

The award, signed by President Biden, is the highest honor the federal government can grant to a federal civilian employee. NASA Administrator Bill Nelson and Deputy Administrator Pam Melroy presented Cabana with the award during a ceremony at NASA Headquarters in Washington on Jan. 10. Cabana most recently served as NASA’s associate administrator, which is the agency’s highest ranking civil servant, from 2021 until he retired from the agency at the end of 2023. “A true public servant, Bob has spent his entire career in service to his country. I can think of no one more deserving of this rare honor than Bob,” said Nelson. “From his time as a naval aviator to his role as associate administrator of NASA, Bob has dedicated his life to improving his country. I join with President Biden in thanking Bob for his dedication and commitment.” The award recognized Cabana for his roles as a Marine aviator, test pilot, astronaut and becoming the first American to enter the International Space Station. He was further recognized for continuing to push for the bounds of the possible, launching the James Webb Space Telescope, the Artemis I mission and the Orion spacecraft which will send humans back to the Moon for the first time in decades. As a NASA astronaut, Cabana flew in space four times, including twice as commander. His final space shuttle flight in 1998 was the first International Space Station assembly mission. Cabana also was the director of the agency’s Kennedy Space Center in Florida for more than a decade. There he led its transition from retirement of the space shuttle to a multi-user spaceport once again launching NASA astronauts to low Earth orbit, and for the first time, doing so with commercial partners. As NASA associate administrator, Cabana led the agency’s 10 center directors, as well as the mission directorate associate administrators at NASA Headquarters. He was the agency’s chief operating officer for more than 18,000 employees and oversaw an annual budget of more than $25 billion. Cabana was selected as an astronaut candidate in June 1985 and completed training in July 1986. He logged 38 days in space during four shuttle missions. Cabana was a pilot aboard space shuttle Discovery on both the STS-41 mission in October 1990 that deployed the Ulysses spacecraft and the STS-53 mission in December 1992. He was the mission commander aboard space shuttle Columbia for the STS-65 mission in July 1994 that conducted experiments as part of the second International Microgravity Laboratory mission. He commanded space shuttle Endeavour for the STS-88 mission in December 1998. Cabana was appointed a member of the Federal Senior Executive Service in 2000 and served in numerous senior management positions at NASA’s Johnson Space Center in Houston, ultimately becoming deputy director. He was named director of NASA’s Stennis Space Center in Mississippi in October 2007 and a year later was selected as NASA Kennedy director. Born in Minneapolis, Cabana graduated from the U.S. Naval Academy in 1971 with a bachelor’s degree in mathematics. He became a naval aviator and graduated with distinction from the U.S. Naval Test Pilot School in 1981. In his career, Cabana logged over 7,000 hours in more than 50 different kinds of aircraft. He retired as a colonel from the U.S. Marine Corps in September 2000. In addition to receiving the President’s Award for Distinguished Federal Service, Cabana’s accomplishments have been recognized with induction into the Astronaut Hall of Fame and being named an Associate Fellow in the American Institute of Aeronautics and Astronautics and a Fellow in the Society of Experimental Test Pilots.

But it is a rare class of star that NASA’s Hubble Space Telescope explored by looking deeply into the open star cluster M67, roughly 2,800 light-years away. Forensics with Hubble data show that the star has had a tumultuous life, mixing with two other stars gravitationally bound together in a remarkable triple-star system. The star has a kinship to so-called “blue stragglers,” which are hotter, brighter, and bluer than expected because they are likely the result of mergers between stars. Evolution of a “Blue Lurker” Star in a Triple System Panel 1: A triple star system containing three Sun-like stars. Two are very tightly orbiting. The third star has a much wider orbit. Panel 2: The close stellar pair spiral together and merge to form one more massive star. Panel 3: The merged star evolves into a giant star. As the huge photosphere expands, some of the material falls onto the outer companion, causing the companion to grow larger and its rotation rate to increase. Panels 4-5: The central merged star eventually burns out and forms a massive white dwarf, and the outer companion spirals in towards the white dwarf, leaving a binary star system with a tighter orbit. Panel 6: The surviving outer companion is much like our Sun but nicknamed a “blue lurker.” Although it is slightly brighter bluer than expected because of the earlier mass-transfer from the central star and is now rotating very rapidly, these features are subtle. The star could easily be mistaken for a normal Sun-like star despite its exotic evolutionary history. NASA, ESA, Leah Hustak (STScI) The blue lurker is spinning much faster than expected, an unusual behavior that led to its identification. Otherwise it looks like a normal Sun-like star. The term “blue” is a bit of a misnomer because the star’s color blends in with all the other solar-mass stars in the cluster. Hence it is sort of “lurking” among the common stellar population. The spin rate is evidence that the lurker must have siphoned in material from a companion star, causing its rotation to speed up. The star’s high spin rate was discovered with NASA’s retired Kepler space telescope. While normal Sun-like stars typically take about 30 days to complete one rotation, the lurker takes only four days. How the blue lurker got that way is a “super complicated evolutionary story,” said Emily Leiner of Illinois Institute of Technology in Chicago. “This star is really exciting because it’s an example of a star that has interacted in a triple-star system.” The blue lurker originally rotated more slowly and orbited a binary system consisting of two Sun-like stars. Around 500 million years ago, the two stars in that binary merged, creating a single, much more massive star. This behemoth soon swelled into a giant star, dumping some of its own material onto the blue lurker and spinning it up in the process. Today, we observe that the blue lurker is orbiting a white dwarf star — the burned out remains of the massive merger. “We know these multiple star systems are fairly common and are going to lead to really interesting outcomes,” Leiner explained. “We just don’t yet have a model that can reliably connect through all of those stages of evolution. Triple-star systems are about 10 percent of the Sun-like star population. But being able to put together this evolutionary history is challenging.” Hubble observed the white dwarf companion star that the lurker orbits. Using ultraviolet spectroscopy, Hubble found the white dwarf is very hot (as high as 23,000 degrees Fahrenheit, or roughly three times the Sun’s surface temperature) and a heavyweight at 0.72 solar masses. According to theory, hot white dwarfs in M67 should be only about 0.5 solar masses. This is evidence that the white dwarf is the byproduct of the merger of two stars that once were part of a triple-star system. “This is one of the only triple systems where we can tell a story this detailed about how it evolved,” said Leiner. “Triples are emerging as potentially very important to creating interesting, explosive end products. It’s really unusual to be able to put constraints on such a system as we are exploring.” Leiner’s results are being presented at the 245th meeting of the American Astronomical Society in Washington, D.C. The Hubble Space Telescope has been operating for over three decades and continues to make ground-breaking discoveries that shape our fundamental understanding of the universe. Hubble is a project of international cooperation between NASA and ESA (European Space Agency). NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages the telescope and mission operations. Lockheed Martin Space, based in Denver, also supports mission operations at Goddard.

Credits: Image: NASA, ESA, CSA, STScI; Science: Emma Lieb (University of Denver), Ryan Lau (NSF NOIRLab), Jennifer Hoffman (University of Denver) Astronomers have long tried to track down how elements like carbon, which is essential for life, become widely distributed across the universe. Now, NASA’s James Webb Space Telescope has examined one ongoing source of carbon-rich dust in our own Milky Way galaxy in greater detail: Wolf-Rayet 140, a system of two massive stars that follow a tight, elongated orbit. As they swing past one another (within the central white dot in the Webb images), the stellar winds from each star slam together, the material compresses, and carbon-rich dust forms. Webb’s latest observations show 17 dust shells shining in mid-infrared light that are expanding at regular intervals into the surrounding space. Image A: Compare Observations of Wolf-Rayet 140 (MIRI Images) Two mid-infrared images from NASA’s James Webb Space Telescope of Wolf-Rayet 140 show carbon-rich dust moving in space. At right, the two triangles from the main images are matched up to show how much difference 14 months makes: The dust is racing away from the central stars at almost 1% the speed of light. These stars are 5,000 light-years away in our own Milky Way galaxy. Image: NASA, ESA, CSA, STScI; Science: Emma Lieb (University of Denver), Ryan Lau (NSF NOIRLab), Jennifer Hoffman (University of Denver) “The telescope not only confirmed that these dust shells are real, its data also showed that the dust shells are moving outward at consistent velocities, revealing visible changes over incredibly short periods of time,” said Emma Lieb, the lead author of the new paper and a doctoral student at the University of Denver in Colorado. Every shell is racing away from the stars at more than 1,600 miles per second (2,600 kilometers per second), almost 1% the speed of light. “We are used to thinking about events in space taking place slowly, over millions or billions of years,” added Jennifer Hoffman, a co-author and a professor at the University of Denver. “In this system, the observatory is showing that the dust shells are expanding from one year to the next.” Like clockwork, the stars’ winds generate dust for several months every eight years, as the pair make their closest approach during a wide, elongated orbit. Webb also shows how dust formation varies — look for the darker region at top left in both images. Video A: Fade Between 2022 and 2023 Observations of Wolf-Rayet 140 This video alternates between two mid-infrared light observations from NASA’s James Webb Space Telescope of Wolf-Rayet 140. Over only 14 months, Webb showed the dust in the system has expanded. This two-star system has sent out more than 17 shells of dust over 130 years. Video: NASA, ESA, CSA, STScI.; Science: Emma Lieb (University of Denver), Ryan Lau (NSF NOIRLab), Jennifer Hoffman (University of Denver) Video B: Stars’ Orbits in Wolf-Rayet 140 (Visualization) When the two massive stars in Wolf-Rayet 140 swing past one another, their winds collide, material compresses, and carbon-rich dust forms. The stronger winds of the hotter star in the Wolf-Rayet system blow behind its slightly cooler (but still hot) companion. The stars create dust for several months in every eight-year orbit. Video: NASA, ESA, CSA, Joseph Olmsted (STScI). The telescope’s mid-infrared images detected shells that have persisted for more than 130 years. (Older shells have dissipated enough that they are now too dim to detect.) The researchers speculate that the stars will ultimately generate tens of thousands of dust shells over hundreds of thousands of years. “Mid-infrared observations are absolutely crucial for this analysis, since the dust in this system is fairly cool. Near-infrared and visible light would only show the shells that are closest to the star,” explained Ryan Lau, a co-author and astronomer at NSF NOIRLab in Tuscon, Arizona, who led the initial research about this system. “With these incredible new details, the telescope is also allowing us to study exactly when the stars are forming dust — almost to the day.” The dust’s distribution isn’t uniform. Though this isn’t obvious at first glance, zooming in on the shells in Webb’s images reveals that some of the dust has “piled up,” forming amorphous, delicate clouds that are as large as our entire solar system. Many other individual dust particles float freely. Every speck is as small as one-hundredth the width of a human hair. Clumpy or not, all of the dust moves at the same speed and is carbon rich. The Future of This System What will happen to these stars over millions or billions of years, after they are finished “spraying” their surroundings with dust? The Wolf-Rayet star in this system is 10 times more massive than the Sun and nearing the end of its life. In its final “act,” this star will either explode as a supernova — possibly blasting away some or all of the dust shells — or collapse into a black hole, which would leave the dust shells intact. Though no one can predict with any certainty what will happen, researchers are rooting for the black hole scenario. “A major question in astronomy is, where does all the dust in the universe come from?” Lau said. “If carbon-rich dust like this survives, it could help us begin to answer that question.” “We know carbon is necessary for the formation of rocky planets and solar systems like ours,” Hoffman added. “It’s exciting to get a glimpse into how binary star systems not only create carbon-rich dust, but also propel it into our galactic neighborhood.” These results have been published in the Astrophysical Journal Letters and were presented in a press conference at the 245th meeting of the American Astronomical Society in National Harbor, Maryland. The James Webb Space Telescope is the world’s premier space science observatory. Webb will solve mysteries in our solar system, look beyond to distant worlds around other stars, and probe the mysterious structures and origins of our universe and our place in it.

Measurements from space support wildfire risk predictions Researchers demonstrated that data from the International Space Station’s ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) instrument played a significant role in the ability of machine learning algorithms to predict wildfire susceptibility. This result could help support development of effective strategies for predicting, preventing, monitoring, and managing wildfires. As the frequency and severity of wildfires increases worldwide, experts need reliable models of fire susceptibility to protect public safety and support natural resource planning and risk management. ECOSTRESS measures evapotranspiration, water use efficiency, and other plant-water dynamics on Earth. Researchers report that its water use efficiency data consistently emerged as the leading factor in predicting wildfires, with evaporative stress and topographic slope data also significant. This ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station evapotranspiration image of California’s Central Valley in May 2022 shows high water use (blue) and dry conditions (brown). NASA Combining instruments provides better emissions data Scientists found that averaging data from the International Space Station’s OCO‐3 and EMIT external instruments can accurately measure the rate of carbon dioxide emissions from power plants. This work could improve emissions monitoring and help communities respond to climate change. Carbon dioxide emissions from fossil fuel combustion make up nearly a third of human-caused emissions and are a major contributor to climate change. In many places, though, scientists do not know exactly how much carbon dioxide these sources emit. The Orbiting Carbon Observatory-3 or OCO-3 can quantify emissions over large areas and Earth Surface Mineral Dust Source Investigation data can help determine emissions from individual facilities. The researchers suggest future work continue to investigate the effect of wind conditions on measurements.

NASA Thunderstorm phenomena observed from space Observations by the International Space Station’s Atmosphere-Space Interactions Monitor (ASIM) instrument during a tropical cyclone in 2019 provide insight into the formation and nature of blue corona discharges often observed at the tops of thunderclouds. A better understanding of such processes in Earth’s upper atmosphere could improve atmospheric models and weather and climate predictions. Scientists do not fully understand the conditions that lead to formation of blue corona discharges, bursts of electrical streamers, which are precursors to lightning. Observations from the ground are affected by scattering and absorption in the clouds. ASIM, a facility from ESA (European Space Agency), provides a unique opportunity for observing these high-atmosphere events from space.

NASA’s SPHEREx observatory will use a technique called spectroscopy across the entire sky, capturing the universe in more than 100 colors.Credit: BAE Systems Media accreditation is open for the launch of two NASA missions that will explore the mysteries of our universe and Sun. The agency is targeting late February to launch its SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer) observatory, a space telescope that will create a 3D map of the entire sky to help scientists investigate the origins of our universe. NASA’s PUNCH (Polarimeter to Unify the Corona and Heliosphere) mission, which will study origins of the Sun’s outflow of material, or the solar wind, also will ride to space with the telescope. NASA and SpaceX will launch the missions aboard the company’s Falcon 9 rocket from Space Launch Complex 4E at Vandenberg Space Force Base in California. Accredited media will have the opportunity to participate in a series of prelaunch briefings and interviews with key mission personnel, including a science briefing the week of launch. NASA will communicate additional details regarding the media event schedule as the launch date approaches. Media interested in covering the launch must apply for media accreditation. The application deadline for U.S. citizens is 11:59 p.m. EST, Thursday, Feb. 6, while international media without U.S. citizenship must apply by 11:59 p.m., Monday, Jan. 20. NASA’s media accreditation policy is available online. For questions about accreditation, please email: ksc-media-accreditat@mail.nasa.gov. For other mission questions, please contact the newsroom at NASA’s Kennedy Space Center in Florida at 321-867-2468. Para obtener información sobre cobertura en español en el Centro Espacial Kennedy o si desea solicitar entrevistas en español, comuníquese con Antonia Jaramillo: 321-501-8425, o Messod Bendayan: 256-930-1371. Updates about spacecraft launch preparations are available on the agency’s SPHEREx blog and PUNCH blog. The SPHEREx mission will observe hundreds of millions of stars and galaxies in infrared light, a range of wavelengths not visible to the human eye. With this map, SPHEREx will enable scientists to study inflation, or the rapid expansion of the universe a fraction of a second after the big bang. The observatory also will measure the collective glow from galaxies near and far, including light from hidden galaxies that individually haven’t been observed, and look for reservoirs of water, carbon dioxide, and other key ingredients for life in our home galaxy. Launching as a rideshare with SPHEREx, the agency’s PUNCH mission is made up of four suitcase-sized satellites that will spread out around Earth’s day-night line to observe the Sun and space with a combined field of view. Working together, the four satellites will map out the region where the Sun’s outer atmosphere, the corona, transitions to the solar wind, or the constant outflow of material from the Sun. The SPHEREx observatory is managed by NASA’s Jet Propulsion Laboratory in Southern California for the Astrophysics Division within the agency’s Science Mission Directorate in Washington. The mission principal investigator is based jointly at NASA JPL and Caltech. Formerly Ball Aerospace, BAE Systems built the telescope, supplied the spacecraft bus, and performed observatory integration. The science analysis of the SPHEREx data will be conducted by a team of scientists located at 10 institutions in the U.S., two in South Korea, and one in Taiwan. Data will be processed and archived at IPAC at Caltech. The SPHEREx data set will be publicly available. The agency’s PUNCH mission is led by Southwest Research Institute’s office in Boulder, Colorado.

Besides stars, the United States Navy uses quasars as beacons. Quasars are distant galaxies with supermassive black holes, surrounded by brilliantly hot disks of swirling gas that can blast off jets of material. Following up on the groundbreaking 2020 discovery of newborn jets in a number of quasars, aspiring naval officer Olivia Achenbach of the United States Naval Academy has used NASA’s Hubble Space Telescope to reveal surprising properties of one of them, quasar J0742+2704. “The biggest surprise was seeing the distinct spiral shape in the Hubble Space Telescope images. At first I was worried I had made an error,” said Achenbach, who made the discovery during the course of a four-week internship. Quasar J0742+2704 (center) became the subject of astronomers’ interest after it was discovered to have a newborn jet blasting from the disk around its supermassive black hole in 2020, using the Karl G. Jansky Very Large Array (VLA) radio observatory. This led to follow-up with other observatories in an effort to determine the properties of the galaxy and what may have triggered the jet. While the jet itself cannot be seen in this Hubble Space Telescope infrared-light image, the spiral shape of J0742+2704 is clear, with faint but detectable arms branching above and below the galaxy center. This was a big surprise to the research team, as quasars hosting jets are typically elliptical-shaped, and its suspected that messy mergers with other galaxies are what funnel gas toward the black hole and fuel jets. These mergers would also disrupt any spiral formation a galaxy may have had before mixing its contents with another galaxy. Though its intact spiral shape means it has not experienced a major merger, Hubble does show evidence that its lower arm has been disrupted, possibly by the tidal forces of interaction with another galaxy. This could mean that jets can be triggered by a far less involved, dramatic interaction of galaxies than a full merger. The large galaxy to the lower right of the quasar appears to be a ring galaxy, another sign of interaction. Some ring galaxies form after a small galaxy passes through the center of a larger galaxy, reconfiguring its gas and dust. The brightest parts of this image — foreground stars and the bright center of the quasar — show the characteristic “starry” spikes produced by Hubble (and other telescopes’) interior structure. They are not actual aspects of the cosmic objects. NASA, ESA, Kristina Nyland (U.S. Naval Research Laboratory); Image Processing: Joseph DePasquale (STScI) “We typically see quasars as older galaxies that have grown very massive, along with their central black holes, after going through messy mergers and have come out with an elliptical shape,” said astronomer Kristina Nyland of the Naval Research Laboratory, Achenbach’s adviser on the research. “It’s extremely rare and exciting to find a quasar-hosting galaxy with spiral arms and a black hole that is more than 400 million times the mass of the Sun — which is pretty big — plus young jets that weren’t detectable 20 years ago,” Nyland said. The unusual quasar takes its place amid an active debate in the astronomy community over what triggers quasar jets, which can be significant in the evolution of galaxies, as the jets can suppress star formation. Some astronomers suspect that quasar jets are triggered by major galaxy mergers, as the material from two or more galaxies mashes together, and heated gas is funneled toward merged black holes. Spiral galaxy quasars like J0742+2704, however, suggest that there may be other pathways for jet formation. While J0742+2704 has maintained its spiral shape, the Hubble image does show intriguing signs of its potential interaction with other galaxies. One of its arms shows distortion, possibly a tidal tail. Hubble captured intriguing hints of interaction, if not full merging, between galaxies including quasar J0742+2704. There is evidence of a distorted tidal tail, or a streamer of gas, that has been pulled out by the gravity of a nearby galaxy. The presence of a ring galaxy also suggests interaction: The distinctive shape of ring galaxies are thought to form when one galaxy passes through another, redistributing its contents into a central core circled by stars and gas. Astronomers will be doing further analysis of Hubble’s detailed spectroscopic data, plus follow-up with other telescopes that can see different types of light, to confirm the distances of the galaxies and how they may be affecting one another. NASA, ESA, Kristina Nyland (U.S. Naval Research Laboratory); Image Processing: Joseph DePasquale (STScI) “Clearly there is something interesting going on. While the quasar has not experienced a major disruptive merger, it may be interacting with another galaxy, which is gravitationally tugging at its spiral arm,” said Nyland. Another galaxy that appears nearby in the Hubble image (though its location still needs to be spectroscopically confirmed) has a ring structure. This rare shape can occur after a galaxy interaction in which a smaller galaxy punches through the center of a spiral galaxy. “The ring galaxy near the quasar host galaxy could be an intriguing clue as to what is happening in this system. We may be witnessing the aftermath of the interaction that triggered this young quasar jet,” said Nyland. Both Achenbach and Nyland emphasize that this intriguing discovery is really a new starting point, and there will be additional multi-wavelength analysis of J0742+2704 with data from NASA’s Chandra X-ray Observatory and the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile. It’s also a case for keeping our eyes on the skies, said Achenbach. “If we looked at this galaxy 20 years, or maybe even a decade ago, we would have seen a fairly average quasar and never known it would eventually be home to newborn jets,” said Achenbach. “It goes to show that if you keep searching, you can find something remarkable that you never expected, and it can send you in a whole new direction of discovery.” The Hubble Space Telescope has been operating for over three decades and continues to make ground-breaking discoveries that shape our fundamental understanding of the universe. Hubble is a project of international cooperation between NASA and ESA (European Space Agency). NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages the telescope and mission operations. Lockheed Martin Space, based in Denver, also supports mission operations at Goddard. The Space Telescope Science Institute in Baltimore, which is operated by the Association of Universities for Research in Astronomy, conducts Hubble science operations for NASA.

6 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) To view this video please enable JavaScript, and consider upgrading to a web browser that supports HTML5 video A thick torus of gas and dust surrounding a supermassive black hole is shown in this artist’s concept. The torus can obscure light that’s generated by material falling into the black hole. Observations by NASA telescopes have helped scientists identify more of these hidden black holes.NASA/JPL-Caltech An effort to find some of the biggest, most active black holes in the universe provides a better estimate for the ratio of hidden to unhidden behemoths. Multiple NASA telescopes recently helped scientists search the sky for supermassive black holes — those up to billions of times heavier than the Sun. The new survey is unique because it was as likely to find massive black holes that are hidden behind thick clouds of gas and dust as those that are not. Astronomers think that every large galaxy in the universe has a supermassive black hole at its center. But testing this hypothesis is difficult because researchers can’t hope to count the billions or even trillions of supermassive black holes thought to exist in the universe. Instead they have to extrapolate from smaller samples to learn about the larger population. So accurately measuring the ratio of hidden supermassive black holes in a given sample helps scientists better estimate the total number of supermassive black holes in the universe. The new study published in the Astrophysical Journal found that about 35% of supermassive black holes are heavily obscured, meaning the surrounding clouds of gas and dust are so thick they block even low-energy X-ray light. Comparable searches have previously found less than 15% of supermassive black holes are so obscured. Scientists think the true split should be closer to 50/50 based on models of how galaxies grow. If observations continue to indicate significantly less than half of supermassive black holes are hidden, scientists will need to adjust some key ideas they have about these objects and the role they play in shaping galaxies. Hidden Treasure Although black holes are inherently dark — not even light can escape their gravity — they can also be some of the brightest objects in the universe: When gas gets pulled into orbit around a supermassive black hole, like water circling a drain, the extreme gravity creates such intense friction and heat that the gas reaches hundreds of thousands of degrees and radiates so brightly it can outshine all the stars in the surrounding galaxy. The clouds of gas and dust that surround and replenish the bright central disk may roughly take the shape of a torus, or doughnut. If the doughnut hole is facing toward Earth, the bright central disk within it is visible; if the doughnut is seen edge-on, the disk is obscured. A supermassive black hole surrounded by a torus of gas and dust is depicted in four different wavelengths of light in this artist’s concept. Visible light (top right) and low-energy X-rays (bottom left) are blocked by the torus; infrared (top left) is scattered and reemitted; and some high energy X-rays (bottom right) can penetrate the torus. NASA/JPL-Caltech Most telescopes can rather easily identify face-on supermassive black holes, though not edge-on ones. But there’s an exception to this that the authors of the new paper took advantage of: The torus absorbs light from the central source and reemits lower-energy light in the infrared range (wavelengths slightly longer than what human eyes can detect). Essentially, the doughnuts glow in infrared. These wavelengths of light were detected by NASA’s Infrared Astronomical Satellite, or IRAS, which operated for 10 months in 1983 and was managed by NASA’s Jet Propulsion Laboratory in Southern California. A survey telescope that imaged the entire sky, IRAS was able to see the infrared emissions from the clouds surrounding supermassive black holes. Most importantly, it could spot edge-on and face-on black holes equally well. IRAS caught hundreds of initial targets. Some of them turned out to be not heavily obscured black holes but galaxies with high rates of star formation that emit a similar infrared glow. So the authors of the new study used ground-based, visible-light telescopes to identify those galaxies and separate them from the hidden black holes. To confirm edge-on, heavily obscured black holes, the researchers relied on NASA’s NuSTAR (Nuclear Spectroscopic Telescope Array), an X-ray observatory also managed by JPL. X-rays are radiated by some of the hottest material around the black hole. Lower-energy X-rays are absorbed by the surrounding clouds of gas and dust, while the higher-energy X-rays observed by NuSTAR can penetrate and scatter off the clouds. Detecting these X-rays can take hours of observation, so scientists working with NuSTAR first need a telescope like IRAS to tell them where to look. NASA’s NuSTAR X-ray telescope, depicted in this artist’s concept, has helped astronomers get a better sense of how many supermassive black holes are hidden from view by thick clouds of gas and dust that surround them.NASA/JPL-Caltech “It amazes me how useful IRAS and NuSTAR were for this project, especially despite IRAS being operational over 40 years ago,” said study lead Peter Boorman, an astrophysicist at Caltech in Pasadena, California. “I think it shows the legacy value of telescope archives and the benefit of using multiple instruments and wavelengths of light together.” Numerical Advantage Determining the number of hidden black holes compared to nonhidden ones can help scientists understand how these black holes get so big. If they grow by consuming material, then a significant number of black holes should be surrounded by thick clouds and potentially obscured. Boorman and his coauthors say their study supports this hypothesis. In addition, black holes influence the galaxies they live in, mostly by impacting how galaxies grow. This happens because black holes surrounded by massive clouds of gas and dust can consume vast — but not infinite — amounts of material. If too much falls toward a black hole at once, the black hole starts coughing up the excess and firing it back out into the galaxy. That can disperse gas clouds within the galaxy where stars are forming, slowing the rate of star formation there. “If we didn’t have black holes, galaxies would be much larger,” said Poshak Gandhi, a professor of astrophysics at the University of Southampton in the United Kingdom and a coauthor on the new study. “So if we didn’t have a supermassive black hole in our Milky Way galaxy, there might be many more stars in the sky. That’s just one example of how black holes can influence a galaxy’s evolution.” More About NuSTAR A Small Explorer mission led by Caltech and managed by NASA’s Jet Propulsion Laboratory in Southern California for the agency’s Science Mission Directorate in Washington, NuSTAR was developed in partnership with the Danish Technical University and the Italian Space Agency (ASI).

International teams of astronomers monitoring a supermassive black hole in the heart of a distant galaxy have detected features never seen before using data from NASA missions and other facilities. The features include the launch of a plasma jet moving at nearly one-third the speed of light and unusual, rapid X-ray fluctuations likely arising from near the very edge of the black hole. Radio images of 1ES 1927+654 reveal emerging structures that appear to be jets of plasma erupting from both sides of the galaxy’s central black hole following a strong radio flare. The first image, taken in June 2023, shows no sign of the jet, possibly because hot gas screened it from view. Then, starting in February 2024, the features emerge and expand away from the galaxy’s center, covering a total distance of about half a light-year as measured from the center of each structure. NSF/AUI/NSF NRAO/Meyer at al. 2025 The source is 1ES 1927+654, a galaxy located about 270 million light-years away in the constellation Draco. It harbors a central black hole with a mass equivalent to about 1.4 million Suns. “In 2018, the black hole began changing its properties right before our eyes, with a major optical, ultraviolet, and X-ray outburst,” said Eileen Meyer, an associate professor at UMBC (University of Maryland Baltimore County). “Many teams have been keeping a close eye on it ever since.” She presented her team’s findings at the 245th meeting of the American Astronomical Society in National Harbor, Maryland. A paper led by Meyer describing the radio results was published Jan. 13 in The Astrophysical Journal Letters. After the outburst, the black hole appeared to return to a quiet state, with a lull in activity for nearly a year. But by April 2023, a team led by Sibasish Laha at UMBC and NASA’s Goddard Space Flight Center in Greenbelt, Maryland, had noted a steady, months-long increase in low-energy X-rays in measurements by NASA’s Neil Gehrels Swift Observatory and NICER (Neutron star Interior Composition Explorer) telescope on the International Space Station. This monitoring program, which also includes observations from NASA’s NuSTAR (Nuclear Spectroscopic Telescope Array) and ESA’s (European Space Agency) XMM-Newton mission, continues. The increase in X-rays triggered the UMBC team to make new radio observations, which indicated a strong and highly unusual radio flare was underway. The scientists then began intensive observations using the NRAO’s (National Radio Astronomy Observatory) VLBA (Very Long Baseline Array) and other facilities. The VLBA, a network of radio telescopes spread across the U.S., combines signals from individual dishes to create what amounts to a powerful, high-resolution radio camera. This allows the VLBA to detect features less than a light-year across at 1ES 1927+654’s distance. Active galaxy 1ES 1927+654, circled, has exhibited extraordinary changes since 2018, when a major outburst occurred in visible, ultraviolet, and X-ray light. The galaxy harbors a central black hole weighing about 1.4 million solar masses and is located 270 million light-years away. Pan-STARRS Radio data from February, April, and May 2024 reveals what appear to be jets of ionized gas, or plasma, extending from either side of the black hole, with a total size of about half a light-year. Astronomers have long puzzled over why only a fraction of monster black holes produce powerful plasma jets, and these observations may provide critical clues. “The launch of a black hole jet has never been observed before in real time,” Meyer noted. “We think the outflow began earlier, when the X-rays increased prior to the radio flare, and the jet was screened from our view by hot gas until it broke out early last year.” A paper exploring that possibility, led by Laha, is under review at The Astrophysical Journal. Both Meyer and Megan Masterson, a doctoral candidate at the Massachusetts Institute of Technology in Cambridge who also presented at the meeting, are co-authors. Using XMM-Newton observations, Masterson found that the black hole exhibited extremely rapid X-ray variations between July 2022 and March 2024. During this period, the X-ray brightness repeatedly rose and fell by 10% every few minutes. Such changes, called millihertz quasiperiodic oscillations, are difficult to detect around supermassive black holes and have been observed in only a handful of systems to date. “One way to produce these oscillations is with an object orbiting within the black hole’s accretion disk. In this scenario, each rise and fall of the X-rays represents one orbital cycle,” Masterson said. If the fluctuations were caused by an orbiting mass, then the period would shorten as the object fell ever closer to the black hole’s event horizon, the point of no return. Orbiting masses generate ripples in space-time called gravitational waves. These waves drain away orbital energy, bringing the object closer to the black hole, increasing its speed, and shortening its orbital period. Over two years, the fluctuation period dropped from 18 minutes to just 7 — the first-ever measurement of its kind around a supermassive black hole. If this represented an orbiting object, it was now moving at half the speed of light. Then something unexpected happened — the fluctuation period stabilized. In this artist’s concept, matter is stripped from a white dwarf (sphere at lower right) orbiting within the innermost accretion disk surrounding 1ES 1927+654’s supermassive black hole. Astronomers developed this scenario to explain the evolution of rapid X-ray oscillations detected by ESA’s (European Space Agency) XMM-Newton satellite. ESA’s LISA (Laser Interferometer Space Antenna) mission, due to launch in the next decade, should be able to confirm the presence of an orbiting white dwarf by detecting the gravitational waves it produces. NASA/Aurore Simonnet, Sonoma State University “We were shocked by this at first,” Masterson explained. “But we realized that as the object moved closer to the black hole, its strong gravitational pull could begin to strip matter from the companion. This mass loss could offset the energy removed by gravitational waves, halting the companion’s inward motion.” So what could this companion be? A small black hole would plunge straight in, and a normal star would quickly be torn apart by the tidal forces near the monster black hole. But the team found that a low-mass white dwarf — a stellar remnant about as large as Earth — could remain intact close to the black hole’s event horizon while shedding some of its matter. A paper led by Masterson summarizing these results will appear in the Feb. 13 edition of the journal Nature. This model makes a key prediction, Masterson notes. If the black hole does have a white dwarf companion, the gravitational waves it produces will be detectable by LISA (Laser Interferometer Space Antenna), an ESA mission in partnership with NASA that is expected to launch in the next decade.

Following the historic year of 1969 that saw two successful Moon landings, 1970 opened on a more sober note. Ever-tightening federal budgets forced NASA to rescope its future lunar landing plans. The need for a Saturn V to launch an experimental space station in 1972 forced the cancellation of the final Moon landing mission and an overall stretching out of the Moon landing flights. Apollo 13 slipped to April, but the crew of James Lovell, Thomas “Ken” Mattingly, and Fred W. Haise and their backups John Young, John “Jack” Swigert, and Charles Duke continued intensive training for the landing at Fra Mauro. Training included practicing their surface excursions and water egress, along with time in spacecraft simulators. The three stages of the Apollo 14 Saturn V arrived at the launch site and workers began the stacking process for that mission now planned for October 1970. Scientists met in Houston to review the preliminary findings from their studies of the lunar samples returned by Apollo 11. Apollo Program Changes Apollo Moon landing plans in early 1970, with blue indicating completed landings, green planned landings at the time, and red canceled landings. Illustration of the Apollo Applications Program, later renamed Skylab, experimental space station then planned for 1972. On Jan. 4, 1970, NASA Deputy Administrator George Low announced the cancellation of Apollo 20, the final planned Apollo Moon landing mission. The agency needed the Saturn V rocket that would have launched Apollo 20 to launch the Apollo Applications Program (AAP) experimental space station, renamed Skylab in February 1970. Since previous NASA Administrator James Webb had precluded the building of any additional Saturn V rockets in 1968, this proved the only viable yet difficult solution. In other program changes, on Jan. 13 NASA Administrator Thomas Paine addressed how NASA planned to deal with ongoing budgetary challenges. Lunar landing missions would now occur every six months instead of every four, and with the slip of Apollo 13 to April, Apollo 14 would now fly in October instead of July. Apollo 15 and 16 would fly in 1971, then AAP would launch in 1972, and three successive crews would spend, 28, 56, and 56 days aboard the station. Lunar landing missions would resume in 1973, with Apollo 17, 18, and 19 closing out the program by the following year.

Wernher von Braun in his office at NASA Headquarters in Washington, D.C. In addition to programmatic changes, several key management changes took place at NASA in January 1970. On Nov. 26, 1969, Christopher Kraft , the director of flight operations at the Manned Spacecraft Center (MSC), now NASA’s Johnson Space Center in Houston, assumed the position of MSC deputy director. On Dec. 28, MSC Director Robert Gilruth named Sigurd “Sig” Sjoberg, deputy director of flight operations since 1963, to succeed Kraft. At NASA Headquarters in Washington, D.C., Associate Administrator for Manned Space Flight George Mueller resigned his position effective Dec. 10, 1969. To replace Mueller, on Jan. 8, NASA Administrator Paine named Dale Myers, vice president and general manager of the space shuttle program at North American Rockwell Corporation. On Jan. 27, Paine announced that Wernher von Braun, designer of the Saturn family of rockets and director of the Marshall Space Flight Center in Huntsville, Alabama, since its establishment in 1960, would move to NASA Headquarters and assume the position of deputy associate administrator for planning. Apollo 11 Lunar Science Symposium Sign welcoming scientists to the Apollo 11 Lunar Science Conference. Apollo 11 astronaut Edwin “Buzz” Aldrin addresses a reception at the First Lunar Science Conference. Between Jan. 5 and 8, 1970, several hundred scientists, including all 142 U.S. and international principal investigators provided with Apollo 11 samples, gathered in downtown Houston’s Albert Thomas Exhibit and Convention Center for the Apollo 11 Lunar Science Conference. During the conference, the scientists discussed the chemistry, mineralogy, and petrology of the lunar samples, the search for carbon compounds and any evidence of organic material, the results of dating of the samples, and the results returned by the Early Apollo Surface Experiments Package (EASEP). Senior NASA managers including Administrator Paine, Deputy Administrator Low, and Apollo Program Director Rocco Petrone attended the conference, and Apollo 11 astronaut Edwin “Buzz” Aldrin gave a keynote speech at a dinner reception. The prestigious journal Science dedicated its Jan. 30, 1970, edition to the papers presented at the conference, dubbing it “The Moon Issue”. The Lunar Science Conference evolved into an annual event, renamed the Lunar and Planetary Science Conference in 1978, and continues to attract scientists from around the world to discuss the latest developments in lunar and planetary exploration.

Managers released the Apollo 12 Command Module (CM) Yankee Clipper from quarantine and shipped it back to its manufacturer, the North American Rockwell plant in Downey, California, on Jan. 12. Engineers there completed a thorough inspection of the spacecraft and eventually prepared it for public display. NASA transferred Yankee Clipper to the Smithsonian Institution in 1973, and today the capsule resides at the Virginia Air & Space Center in Hampton, Virginia. NASA also released from quarantine the lunar samples and the parts of the Surveyor 3 spacecraft returned by the Apollo 12 astronauts. The scientists received their allocated samples in mid-February, while after initial examination in the Lunar Receiving Laboratory (LRL) the Surveyor parts arrived at NASA’s Jet Propulsion Laboratory in Pasadena, California, for detailed analysis. Apollo 13 As the first step in the programmatic rescheduling of all Moon landings, on Jan. 7, NASA announced the delay of the Apollo 13 launch from March 12 to April 11. The Saturn V rocket topped with the Apollo spacecraft had rolled out the previous December to Launch Pad 39A where workers began tests on the vehicle. The prime crew of Lovell, Mattingly, and Haise, and their backups Young, Swigert, and Duke, continued to train for the 10-day mission to land in the Fra Mauro region of the Moon. During water recovery exercises, Apollo 13 astronauts (in white flight suits) Thomas “Ken” Mattingly, left, Fred Haise, and James Lovell in the life raft after emerging from the boilerplate Apollo capsule.

Apollo 13 prime crew members Lovell, Mattingly, and Haise completed their water egress training in the Gulf of Mexico near the coast of Galveston, Texas, on Jan. 24. With support from the Motorized Vessel Retriever, the three astronauts entered a boilerplate Apollo CM. Sailors lowered the capsule into the water, first in the Stable 2 or apex down position. Three self-inflating balloons righted the spacecraft into the Stable 1 apex up position within a few minutes. With assistance from the recovery team, Lovell, Mattingly, and Haise exited the spacecraft onto a life raft. A helicopter lifted them out of the life rafts using Billy Pugh nets and returned them to Retriever. Later that day, the astronauts returned to the MSC to examine Moon rocks in the LRL that the Apollo 12 astronauts had returned the previous November. During their 33.5 hours on the Moon’s surface, Lovell and Haise planned to conduct two four-hour spacewalks to set up the Apollo Lunar Surface Experiment Package (ALSEP), a suite of five investigations designed to collect data about the lunar environment after the astronauts’ departure, and to conduct geologic explorations of the landing site. Mattingly planned to remain in the Command and Service Module (CSM), conducting geologic observations from lunar orbit including photographing potential future landing sites. Lovell and Haise conducted several simulations of the spacewalk timelines, including setting up the ALSEP equipment, practicing taking core samples, and photographing their activities for documentation purposes. They and their backups conducted practice sessions with the partial gravity simulator, also known as POGO, an arrangement of harnesses and servos that simulated walking in the lunar one-sixth gravity. Lovell and Young completed several flights in the Lunar Landing Training Vehicle (LLTV) that simulated the flying characteristics of the Lunar Module (LM) for the final several hundred feet of the descent to the surface.

In the LRL, technicians prepared the Apollo Lunar Sample Return Containers (ALSRC), or rock boxes, for Apollo 13. Like all missions, Apollo 13 carried two ALSRCs, with each box and lid manufactured from a single block of aluminum. Workers placed sample containers and bags and two 2-cm core sample tubes inside the two ALSRCs. Once loaded, technicians sealed the boxes under vacuum conditions so that they would not contain pressure greater than lunar ambient conditions. Engineers at MSC prepared the American flag that Lovell and Haise planned to plant on the Moon for stowage on the LM’s forward landing strut.

As part of the rescheduling of Moon missions, NASA delayed the launch of the next flight, Apollo 14, from July to October 1970. The CSM and the LM had arrived at NASA’s Kennedy Space Center (KSC) in Florida late in 1969 and technicians conducted tests on the vehicles in the Manned Spacecraft Operations Building (MSOB). On Jan. 12, workers lowered the ascent stage of the LM onto the CSM to perform a docking test – the next time the two vehicles docked they would be on the way to the Moon and the test verified their compatibility. Workers mated the two stages of the LM on Jan. 20. The first stage of Apollo 14’s Saturn V inside the Vehicle Assembly Building (VAB) at NASA’s Kennedy Space Center (KSC) in Florida. The second stage of Apollo 14’s Saturn V arrives at the VAB. The third stage of Apollo 14’s Saturn V arrives at KSC. The three stages of the Apollo 14 Saturn V arrived in KSC’s cavernous Vehicle Assembly Building (VAB) in mid-January and while workers stacked the first stage on its Mobile Launch Platform on Jan. 14, they delayed stacking the remainder of the rocket stages until May 1970. That decision proved fortunate, since engineers needed to modify the second stage engines following the pogo oscillations experienced during the Apollo 13 launch.

NASA’s Office of STEM Engagement at Johnson Space Center in Houston offers students a unique gateway to opportunity through the High School Aerospace Scholars (HAS) program. The initiative provides Texas juniors with hands-on experience in space exploration, working on projects ranging from rocket building to problem-solving in collaborative teams. The stories of HAS alumni highlight the program’s impact, showcasing how it has opened doors to diverse careers in STEM and inspired graduates to empower others. Johnson Community Engagement Lead Jessica Cordero, who served as the manager of the HAS program from 2018 to 2021, reflected on her time with the students: “I had the privilege of working with so many incredible students who brought imagination and determination to their dreams,” she said. “During HAS, they connected with peers who shared their passion for NASA and STEM, and by the time they completed the program, they had a clear vision of the degrees they would pursue in college. These students are the Artemis Generation—we are in great hands!” Meet Former HAS Student Neel Narayan For Neel Narayan, NASA’s HAS program was a transformative experience that reshaped his understanding of space exploration and his place within it. Through his time in the program, Narayan learned to navigate complex challenges with confidence. “My experience working with difficult information at HAS, combined with having mentors explain the unknown, taught me to be okay with confusion and comfortable with solving hard problems,” he said. “That’s what STEM is all about.” Neel Narayan at NASA’s High School Aerospace Scholars (HAS) 20th anniversary ceremony. Before participating in the program, Narayan had a narrow view of what a STEM career entailed: long equations and solitary hours behind a computer. HAS completely dismantled that misconception. He said the program, “broke the most complex concepts into granular bites of digestible information, showing that complexity can be distilled if done correctly.” “During the one-week onsite experience, I was talking to scientists, building rockets, and exploring NASA facilities—none of which involved equations!” he said. “HAS taught me that STEM is not confined to technical work.” Narayan describes HAS as an eye-opening experience that redefined his approach to problem-solving. “Most of us are unaware of what we don’t know,” he said. “In collaborating with others, I was made aware of solutions that I didn’t know existed. The greatest asset you can have when solving a problem is another person.” He credits the HAS community, especially his fellow scholars, with shaping his academic and professional growth. “I benefited most from the networking opportunities, particularly with the other HAS scholars in my cohort,” he said. “For those of us studying together in California, we’ve met up to discuss work, school, and external opportunities. Everyone in the program comes out very successful, and I’m grateful to have met those people and to still stay in touch with them.” For high school students considering STEM but unsure of their direction, Narayan offers simple advice: keep exploring. “You don’t need to know your career path yet—in fact, you shouldn’t,” he said. “There is no better field to explore than STEM because of its vastness.” Neel Narayan, University of Stanford. Narayan is currently pursuing a master’s degree in computational and mathematical engineering at Stanford University after earning an undergraduate degree in computer science. With his graduate program, Narayan is building on the foundation he developed through NASA’s HAS program. Narayan aspires to contribute to the agency’s innovation and groundbreaking work. “NASA’s research changes the world, and being part of that mission is a dream I’ve had for a while,” he said. Meet Sarah Braun NASA’s HAS program solidified Sarah Braun’s understanding of how a STEM career could encompass her diverse interests, from design and education to plotting spacecraft orbits and planning launches. From her time in HAS to her current space exploration career, Braun believes STEM can be as multifaceted as the people who pursue it. “HAS showed me the options ahead were as endless as my imagination,” she said. “The program convinced me that all my skills would be put to use in STEM, including getting to be creative and artistic.” Sarah Braun engages in science, technology, engineering, and mathematics outreach at the Air Zoo Aerospace & Science Museum in Portage, Michigan, standing beside a Gemini model. The program gave her the opportunity to network, problem-solve, and collaborate with students from various backgrounds. “Learning how to communicate designs I could picture in my head was the biggest challenge, but by observing my teammates and mentors, I built the skills I needed.” The networking opportunities she gained through HAS have also been instrumental to her academic and career growth. “The mentors I met through HAS have supported me throughout college and into my early career,” she said. “They taught me countless technical skills and how to best take advantage of my college years. I would never have made it to where I am today without HAS!” After completing the HAS program, Braun interned with NASA, where she worked on space systems and paved the way for her career at Collins Aerospace. Sarah Braun at the National Museum of the U.S. Air Force in Dayton, Ohio. She stands in front of the hardware she now works on at Collins Aerospace. Braun advises high school students uncertain about their career paths to get engaged and ask questions. “There are so many people out there who pursue STEM to follow a passion or challenge themselves,” she said. “Talking with people about what they have experienced and learned has been a huge help and inspiration for me throughout the years.” She is also passionate about inspiring and educating others. “Whether I’m leading after-school STEM clubs or mentoring students, outreach and teaching have become my biggest contributions to NASA’s mission of exploration and discovery,” said Braun. Meet Audrey Scott Audrey Scott credits the HAS program with giving her a chance to explore science in the real world. “I experienced the excitement space could bring through livestream events like the landing of NASA’s InSight Lander mission and Cassini’s Grand Finale,” she said. Audrey Scott, front, with fellow 2019 HAS graduates. Scott shared that the HAS program opened her eyes to the vast possibilities within STEM fields. Seeing the many ways to apply a STEM degree in practice broadened her perspective and inspired her to pursue her passion. After HAS, Scott chose to study astrophysics at the University of Chicago in Illinois, where she is now pursuing her Ph.D. in experimental cosmology and laying the groundwork for a future in space exploration. “My time with HAS and its encouragement of STEM excellence gave me the confidence I needed to take the plunge,” said Scott. The program also transformed her approach to teamwork and exposed her to fast-paced problem-solving. “My school didn’t prioritize group projects, so working with people from all different backgrounds and personalities was informative for my future work in college,” she said. “HAS was a safe space to experiment with being both a leader and collaborator.” She encourages high school students uncertain of their path to “try everything.” Scott advises, “If you have a moment of fascination, take advantage of that intellectual and creative energy, and learn something new. Time spent realizing you don’t like something is just as useful as time spent realizing you do.” She also recommends seeking out resources, finding mentors, and talking to everyone. Scott continues to connect with some of her HAS cohort, especially young women navigating STEM paths alongside her. “We’ve been able to support each other through challenges,” she said. “Being part of HAS made me, in a way, part of the NASA family.” Audrey Scott, front, with fellow 2019 HAS graduates. Scott’s HAS experience opened doors to opportunities like the Brooke Owens Fellowship, where she worked on a satellite in partnership with NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and later the Illinois Space Grant award, which took her to NASA’s Jet Propulsion Laboratory in Southern California. She envisions part of her thesis research as a Ph.D. candidate taking place at a NASA center and remains open to a future at the agency. “I’ll continue advocating for space exploration and pushing the boundaries of what’s known,” she said. “In my research, I’m driven by questions like, ‘What did the beginning of the universe look like—and why are we here?’” View the full article

Learn Home First NASA Neurodiversity… Heliophysics Overview Learning Resources Science Activation Teams SME Map Opportunities More Science Activation Stories Citizen Science 2 min read First NASA Neurodiversity Network Intern to Present at the American Geophysical Union Annual Conference The NASA Science Activation Program’s NASA’s Neurodiversity Network (N3) project sponsors a summer internship program for high school students, in which learners on the autism spectrum are matched with NASA Subject Matter Experts. N3 intern Lillian Hall and mentor Dr. Juan Carlos Martinez Oliveros presented Lilly’s summer research project on December 9 at the 2024 American Geophysical Union conference in Washington, D.C. Their poster, entitled “Eclipse Megamovie: Image Processing”, represents the first time an N3 intern has co-authored a presentation at the prestigious AGU conference. The NASA Citizen Science project, Eclipse Megamovie, is leveraging the power of citizen science to construct a high-resolution time-lapse of the Sun’s corona during the April 8, 2024 total solar eclipse. By coordinating the work of hundreds of participants along the path of totality, a substantial dataset of images was obtained. The goal of the project is to unveil dynamic transformations in the Sun’s atmosphere that are only visible during a total solar eclipse. To process the vast quantity of imaging data collected, Lilly assisted Dr. Martinez Oliveros and other researchers in implementing a robust pipeline involving image calibration, registration, and co-location. Image registration techniques aligned the solar features across different frames, compensating for Earth’s rotation and camera movement. Finally, they used imaging techniques to enhance the signal-to-noise ratio, revealing subtle coronal structures and possible dynamics. This comprehensive data processing methodology has enabled the extraction of meaningful scientific information from the Eclipse Megamovie dataset. Here’s what Lilly had to say: “Working with N3 has given me a chance to use my neurodiverse perspective to make an impact on NASA research. Through the processes of my project and the opportunity to share it at the American Geophysical Union conference, I am so grateful to have found my spot in the planetary science field I dream to continue researching in the future.” Learn more about NASA Citizen Science and how you can participate (participation does not require citizenship in any particular country): https://science.nasa.gov/citizen-science/ The N3 project is supported by NASA under cooperative agreement award number 80NSSC21M0004 and is part of NASA’s Science Activation Portfolio.
