Robert Williams is a senior mechanical design engineer and the structures subject matter expert in the Engineering and Test Directorate at NASA’s Stennis Space Center.NASA/Danny Nowlin Living up to, and maintaining, the standard of excellence associated with NASA is what drives Robert Williams at NASA’s Stennis Space Center near Bay St. Louis, Mississippi. A native of Gulfport, Mississippi, Williams said he has had the opportunity to work with and be mentored by “some truly exceptional” engineers, some with careers reaching back to the Apollo era. “I cannot overstate the vast amount of practical knowledge and experience we have at NASA Stennis,” Williams said. “We know how to get things done, and if we do not know, I can guarantee we will figure it out.” Williams is a senior mechanical design engineer and the structures subject matter expert for the NASA Stennis Engineering and Test Directorate. He provides technical oversight related to engineering mechanics and machine design by reviewing analysis and design packages from NASA Stennis contractors and NASA engineers for ongoing projects. Williams also supports projects by performing analysis and creating detailed models, drawings, and system level designs, mostly at the versatile four-stand E Test Complex, where NASA Stennis has 12 active test cells capable of various component, engine, and stage test activities to support the agency and commercial companies. In support of NASA’s Artemis campaign of returning astronauts to the Moon, Williams also has reviewed structural and pipe stress analysis for the exploration upper stage project that will test a new SLS (Space Launch System) rocket stage to fly on future Artemis missions. He performed similar review work for Green Run testing of the SLS core stage at NASA Stennis ahead of the successful launch of the Artemis I uncrewed mission around the Moon. Overall, Williams has been a part of projects on every test stand throughout more than eight years with NASA and five years as a contractor. He has been tasked with solving challenging problems, both individually and as a part of teams. There were times when he was not sure if he or the team would be able to solve the problem or address it effectively, but each time, the NASA Stennis team found a way. “Over the span of my career, I have yet to be in a situation where the challenge was not met,” he said. The opportunity to work with “pretty much all the major space companies in some capacity” is most interesting to Williams. “The best thing is that being a small organization within a relatively small center, there are always opportunities to develop new skills and capabilities to help fill a need or gap,” he said. No matter the task, Williams looks forward to supporting space innovation while living up to, and maintaining, the standard of excellence associated with NASA for the benefit of all.

ESA/Hubble & NASA, J. Dalcanton, R. J. Foley (UC Santa Cruz), C. Kilpatrick A beautiful but skewed spiral galaxy dazzles in this NASA/ESA Hubble Space Telescope image. The galaxy, called Arp 184 or NGC 1961, sits about 190 million light-years away from Earth in the constellation Camelopardalis (The Giraffe). The name Arp 184 comes from the Atlas of Peculiar Galaxies compiled by astronomer Halton Arp in 1966. It holds 338 galaxies that are oddly shaped and tend to be neither entirely elliptical nor entirely spiral-shaped. Many of the galaxies are in the process of interacting with other galaxies, while others are dwarf galaxies without well-defined structures. Arp 184 earned its spot in the catalog thanks to its single broad, star-speckled spiral arm that appears to stretch toward us. The galaxy’s far side sports a few wisps of gas and stars, but it lacks a similarly impressive spiral arm. This Hubble image combines data from three Snapshot observing programs, which are short observations that slotted into time gaps between other proposals. One of the three programs targeted Arp 184 for its peculiar appearance. This program surveyed galaxies listed in the Atlas of Peculiar Galaxies as well as A Catalogue of Southern Peculiar Galaxies and Associations, a similar catalog compiled by Halton Arp and Barry Madore. The remaining two Snapshot programs looked at the aftermath of fleeting astronomical events like supernovae and tidal disruption events — like when a supermassive black hole rips a star apart after it wanders too closely. Since Arp 184 hosted four known supernovae in the past three decades, it is a rich target for a supernova hunt.

6 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) NASA’s SPHEREx mission is observing the entire sky in 102 infrared colors, or wavelengths of light not visible to the human eye. This image shows a section of sky in one wavelength (3.29 microns), revealing a cloud of dust made of a molecule similar to soot or smoke.NASA/JPL-Caltech This image from NASA’s SPHEREx shows the same region of space in a different infrared wavelength (0.98 microns), but the dust cloud is no longer visible. The molecules that compose the dust — polycyclic aromatic hydrocarbons — do not radiate light in this color.NASA/JPL-Caltech After weeks of preparation, the space observatory has begun its science mission, taking about 3,600 unique images per day to create a map of the cosmos like no other. Launched on March 11, NASA’s SPHEREx space observatory has spent the last six weeks undergoing checkouts, calibrations, and other activities to ensure it is working as it should. Now it’s mapping the entire sky — not just a large part of it — to chart the positions of hundreds of millions of galaxies in 3D to answer some big questions about the universe. On May 1, the spacecraft began regular science operations, which consist of taking about 3,600 images per day for the next two years to provide new insights about the origins of the universe, galaxies, and the ingredients for life in the Milky Way. This video shows SPHEREx’s field of view as it scans across one section of sky inside the Large Magellanic Cloud, with rainbow colors representing the infrared wavelengths the telescope’s detectors see. The view from one detector array moves from purple to green, followed by the second array’s view, which changes from yellow to red. The images are looped four times. NASA/JPL-Caltech “Thanks to the hard work of teams across NASA, industry, and academia that built this mission, SPHEREx is operating just as we’d expected and will produce maps of the full sky unlike any we’ve had before,” said Shawn Domagal-Goldman, acting director of the Astrophysics Division at NASA Headquarters in Washington. “This new observatory is adding to the suite of space-based astrophysics survey missions leading up to the launch of NASA’s Nancy Grace Roman Space Telescope. Together with these other missions, SPHEREx will play a key role in answering the big questions about the universe we tackle at NASA every day.” From its perch in Earth orbit, SPHEREx peers into the darkness, pointing away from the planet and the Sun. The observatory will complete more than 11,000 orbits over its 25 months of planned survey operations, circling Earth about 14½ times a day. It orbits Earth from north to south, passing over the poles, and each day it takes images along one circular strip of the sky. As the days pass and the planet moves around the Sun, SPHEREx’s field of view shifts as well so that after six months, the observatory will have looked out into space in every direction. When SPHEREx takes a picture of the sky, the light is sent to six detectors that each produces a unique image capturing different wavelengths of light. These groups of six images are called an exposure, and SPHEREx takes about 600 exposures per day. When it’s done with one exposure, the whole observatory shifts position — the mirrors and detectors don’t move as they do on some other telescopes. Rather than using thrusters, SPHEREx relies on a system of reaction wheels, which spin inside the spacecraft to control its orientation. Hundreds of thousands of SPHEREx’s images will be digitally woven together to create four all-sky maps in two years. By mapping the entire sky, the mission will provide new insights about what happened in the first fraction of a second after the big bang. In that brief instant, an event called cosmic inflation caused the universe to expand a trillion-trillionfold. “We’re going to study what happened on the smallest size scales in the universe’s earliest moments by looking at the modern universe on the largest scales,” said Jim Fanson, the mission’s project manager at NASA’s Jet Propulsion Laboratory in Southern California. “I think there’s a poetic arc to that.” Cosmic inflation subtly influenced the distribution of matter in the universe, and clues about how such an event could happen are written into the positions of galaxies across the universe. When cosmic inflation began, the universe was smaller than the size of an atom, but the properties of that early universe were stretched out and influence what we see today. No other known event or process involves the amount of energy that would have been required to drive cosmic inflation, so studying it presents a unique opportunity to understand more deeply how our universe works. “Some of us have been working toward this goal for 12 years,” said Jamie Bock, the mission’s principal investigator at Caltech and JPL. “The performance of the instrument is as good as we hoped. That means we’re going to be able to do all the amazing science we planned on and perhaps even get some unexpected discoveries.” Color Field The SPHEREx observatory won’t be the first to map the entire sky, but it will be the first to do so in so many colors. It observes 102 wavelengths, or colors, of infrared light, which are undetectable to the human eye. Through a technique called spectroscopy, the telescope separates the light into wavelengths — much like a prism creates a rainbow from sunlight — revealing all kinds of information about cosmic sources. For example, spectroscopy can be harnessed to determine the distance to a faraway galaxy, information that can be used to turn a 2D map of those galaxies into a 3D one. The technique will also enable the mission to measure the collective glow from all the galaxies that ever existed and see how that glow has changed over cosmic time. And spectroscopy can reveal the composition of objects. Using this capability, the mission is searching for water and other key ingredients for life in these systems in our galaxy. It’s thought that the water in Earth’s oceans originated as frozen water molecules attached to dust in the interstellar cloud where the Sun formed. The SPHEREx mission will make over 9 million observations of interstellar clouds in the Milky Way, mapping these materials across the galaxy and helping scientists understand how different conditions can affect the chemistry that produced many of the compounds found on Earth today. More About SPHEREx The SPHEREx mission is managed by JPL for the agency’s Astrophysics Division within the Science Mission Directorate at NASA Headquarters. BAE Systems in Boulder, Colorado, built the telescope and the spacecraft bus. 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. Caltech in Pasadena managed and integrated the instrument. The mission’s principal investigator is based at Caltech with a joint JPL appointment. Data will be processed and archived at IPAC at Caltech. The SPHEREx dataset will be publicly available at the NASA-IPAC Infrared Science Archive. Caltech manages JPL for NASA.

X-ray: NASA/CXC/Northwestern Univ./F. Yusef-Zadeh et al; Radio: NRF/SARAO/MeerKat; Image Processing: NASA/CXC/SAO/N. Wolk Astronomers have discovered a likely explanation for a fracture in a huge cosmic “bone” in the Milky Way galaxy, using NASA’s Chandra X-ray Observatory and radio telescopes. The bone appears to have been struck by a fast-moving, rapidly spinning neutron star, or pulsar. Neutron stars are the densest known stars and form from the collapse and explosion of massive stars. They often receive a powerful kick from these explosions, sending them away from the explosion’s location at high speeds. Enormous structures resembling bones or snakes are found near the center of the galaxy. These elongated formations are seen in radio waves and are threaded by magnetic fields running parallel to them. The radio waves are caused by energized particles spiraling along the magnetic fields. X-ray: NASA/CXC/Northwestern Univ./F. Yusef-Zadeh et al; Radio: NRF/SARAO/MeerKat; Image Processing: NASA/CXC/SAO/N. Wolk This new image shows one of these cosmic “bones” called G359.13142-0.20005 (G359.13 for short), with X-ray data from Chandra (colored blue) and radio data from the MeerKAT radio array in South Africa (colored gray). Researchers also refer to G359.13 as the Snake. Examining this image closely reveals the presence of a break, or fracture, in the otherwise continuous length of G359.13 seen in the image. The combined X-ray and radio data provides clues to the cause of this fracture. Astronomers have now discovered an X-ray and radio source at the location of the fracture, using the data from Chandra and MeerKAT and the National Science Foundation’s Very Large Array. A likely pulsar responsible for these radio and X-ray signals is labeled. A possible extra source of X-rays located near the pulsar may come from electrons and positrons (the anti-matter counterparts to electrons) that have been accelerated to high energies. The researchers think the pulsar likely caused the fracture by smashing into G359.13 at a speed between one million and two million miles per hour. This collision distorted the magnetic field in the bone, causing the radio signal to also become warped. At about 230 light-years long, G359.13 is one of the longest and brightest of these structures in the Milky Way. To put this into context, there are more than 800 stars within that distance from Earth. G359.13 is located about 26,000 light-years from Earth, near the center of the Milky Way. A paper describing these results appeared in the May 2024 issue of the Monthly Notices of the Royal Astronomical Society and is available here. The authors of the study are Farhad Yusuf-Zadeh (Northwestern University), Jun-Hui Zhao (Center for Astrophysics | Harvard & Smithsonian), Rick Arendt (University of Maryland, Baltimore County), Mark Wardle (Macquarie University, Australia), Craig Heinke (University of Alberta), Marc Royster (College of the Sequoias, California), Cornelia Lang (University of Iowa), and Joseph Michail (Northwestern).

With the structure’s vertical orientation, seemingly fragile dimensions, and pale grey color against the blackness of space, the images resemble medical X-rays of a long, thin, bone. The main image shows the structure in its entirety. The inset image is an annotated close-up highlighting an apparent fracture in the bone-like structure. The structure, called G359.13, or “The Snake”, is a Galactic Center Filament. These filament formations are threaded by parallel magnetic fields, and spiraling, energized particles. The particles cause radio waves, which can be detected by radio arrays, in this case by the MeerKAT array in South Africa. In the first composite image, the largely straight filament stretches from the top to the bottom of the vertical frame. At each end of the grey filament is a hazy grey cloud. The only color in the image is neon blue, found in a few specks which dot the blackness surrounding the structure. The blue represents X-rays seen by NASA’s Chandra X-ray Observatory. In the annotated close-up, one such speck appears to be interacting with the structure itself. This is a fast-moving, rapidly spinning neutron star, otherwise known as a pulsar. Astronomers believe that this pulsar has struck the filament halfway down its length, distorting the magnetic field and radio signal. In both images, this distortion resembles a small break, or spur, in the bone-like filament.

Skywatching Skywatching Home What’s Up What to See Tonight Meteor Showers Eclipses Moon Guide More Tips & Guides Skywatching FAQ Night Sky Network Eta Aquarids & Waiting for a Nova! The first week of May brings the annual Eta Aquarid meteors, peaking on the 6th. And sometime in the next few months, astronomers predict a “new star” or nova explosion will become visible to the unaided eye. Skywatching Highlights All Month – Planet Visibility: Venus: Appears very bright and low in the east in the hour before sunrise all month. Mars: Easy to find in the west in the first few hours of the night, all month long. Sets around midnight to 1 a.m. local time. Jupiter: Shines brightly in the west following sunset all month. Early in the month it sets about two hours after the Sun, but by late May it’s setting only an hour after sunset. Saturn: Begins the month next to Venus, low in the eastern sky before sunrise. Quickly separates from Saturn and rises higher in the sky each day before dawn. Daily Highlights May 6 – Eta Aquarid Meteors – The peak of this annual shower is early on the morning of May 6th. The two or three nights before that are also decent opportunities to spy a few shooting stars. On the peak night this year, the Moon sets by around 3 a.m., leaving dark skies until dawn, for ideal viewing conditions. Seeing 10-20 meteors per hour is common for the Northern Hemisphere, while south of the equator, observers tend to see substantially more. May 3 – Mars & Moon: The first quarter Moon appears right next to the Red Planet on the 3rd. Find them in the west during the first half of the night that evening. All month – Venus & Saturn: Low in the eastern sky each morning you’ll find bright Venus paired with much fainter Saturn. They start the month close together, but Saturn pulls away and rises higher over the course of the month. All month – Mars & Jupiter: The planets to look for on May evenings are Mars and Jupiter. They’re visible for a couple of hours after sunset in the western sky. All month – Corona Borealis: Practice finding this constellation in the eastern part of the sky during the first half of the night, so you have a point of comparison when the T CrB nova appears there, likely in the next few months. Transcript What’s Up for May? Four bright planets, morning and night, a chance of meteor showers, and waiting for a nova. May Planet Viewing For planet watching this month, you’ll find Mars and Jupiter in the west following sunset. Mars sticks around for several hours after it gets dark out, but Jupiter is setting by 9:30 or 10 p.m., and getting lower in the sky each day. The first quarter Moon appears right next to the Red Planet on the 3rd. Find them in the west during the first half of the night that evening. Sky chart showing Venus and Saturn with the crescent Moon in the predawn sky on May 23., 2025. NASA/JPL-Caltech In the morning sky, Venus and Saturn are the planets to look for in May. They begin the month appearing close together on the sky, and progressively pull farther apart as the month goes on. For several days in late May, early risers will enjoy a gathering of the Moon with Saturn and Venus in the eastern sky before dawn. Watch as the Moon passes the two planets while becoming an increasingly slimmer crescent. You’ll find the Moon hanging between Venus and Saturn on the 23rd. Eta Aquarid Meteor Shower Early May brings the annual Eta Aquarid meteor shower. These are meteors that originate from Comet Halley. Earth passes through the comet’s dust stream each May, and again in October. Eta Aquarids are fast moving, and a lot of them produce persistent dust trains that linger for seconds after the meteor’s initial streak. This is one of the best annual showers in the Southern Hemisphere, but tends to be more subdued North of the Equator, where we typically see 10-20 meteors per hour. On the peak night this year, the Moon sets by around 3 a.m., leaving dark skies until dawn, for ideal viewing conditions. While the peak is early on the morning of May 6th, the two or three nights before that are also decent opportunities to spy a few shooting stars. Waiting for a Nova Sky chart showing constellation Corona Borealis with the location where nova “T CrB” is predicted to appear. The view depicts the constellation with the nova occurring, indicated by an arrow. NASA/JPL-Caltech Astronomers have been waiting expectantly for light from a distant explosion to reach us here on Earth. An event called a nova is anticipated to occur sometime in the coming months. Some 3,000 light years away is a binary star system called T Coronae Borealis, or “T CrB.” It consists of a red giant star with a smaller white dwarf star orbiting closely around it. Now the giant’s outer atmosphere is all puffed up, and the dwarf star is close enough that its gravity continually captures some of the giant’s hydrogen. About every 80 years, the white dwarf has accumulated so much of the other star’s hydrogen, that it ignites a thermonuclear explosion. And that’s the nova. T Coronae Borealis is located in the constellation Corona Borealis, or the “Northern Crown,” and it’s normally far too faint to see with the unaided eye. But it’s predicted the nova will be as bright as the constellation’s brightest star, which is about as bright as the North Star, Polaris. You’ll find Corona Borealis right in between the two bright stars Arcturus and Vega, and you can use the Big Dipper’s handle to point you to the right part of the sky. Try having a look for it on clear, dark nights before the nova, so you’ll have a comparison when a new star suddenly becomes visible there. A sky chart indicating how to locate the constellation Corona Borealis between the bright stars Arcturus and Vega. The Big Dipper’s handle points in the direction of Corona Borealis. NASA/JPL-Caltech Now, you may have heard about this months ago, as astronomers started keeping watch for the nova midway through 2024, but it hasn’t happened yet. Predicting exactly when novas or any sort of stellar outburst will happen is tricky, but excitement began growing when astronomers observed the star to dim suddenly, much as it did right before its previous nova in 1946. When the nova finally does occur, it won’t stay bright for long, likely flaring in peak brightness for only a few days. And since it’s not predicted again for another 80 years, you might just want to join the watch for this super rare, naked eye stellar explosion in the sky! Here are the phases of the Moon for May. The phases of the Moon for May 2025. NASA/JPL-Caltech You can stay up to date on all of NASA’s missions exploring the solar system and beyond at NASA Science.

Cassiopeia A (Cas A) is a supernova remnant located about 11,000 light-years from Earth in the constellation Cassiopeia. It spans approximately 10 light-years.X-ray: NASA/CXC/SAO, NASA/JPL/Caltech/NuStar; Optical: NASA/STScI/HST; IR: NASA/STScI/JWST, NASA/JPL/CalTech/SST; Image Processing: NASA/CXC/SAO/J. Schmidt, N. Wolk, and K. Arcand Using NASA’s James Webb Space Telescope, astronomers uncovered a mysterious feature within the remnant, nicknamed the “Green Monster,” alongside a puzzling network of ejecta filaments forming a web of oxygen-rich material. When combined with X-rays from NASA’s Chandra X-ray Observatory, the data helped astronomers shed light on the origin of the Green Monster and revealed new insights into the explosion that created Cas A about 340 years ago, from Earth’s perspective. Like with the Cygnus Loop, Chandra has provided a 3-dimensional (3D) printable model that can be used to explore the end stage of a star’s life. These 3D models are based on state-of-the-art theoretical models, computational algorithms, and observations from space-based telescopes like Chandra that give us accurate pictures of these cosmic objects and how they evolve over time.

Inside a laboratory in the Space Systems Processing Facility at NASA’s Kennedy Space Center in Florida, a payload implementation team member harvests ‘Outredgeous’ romaine lettuce growing in the Advanced Plant Habitat ground unit on Thursday, April 24, 2025. The harvest is part of the ground control work supporting Plant Habitat-07, which launched to the International Space Station aboard NASA’s SpaceX 31st commercial resupply services mission. The experiment focuses on studying how optimal and suboptimal moisture conditions affect plant growth, nutrient content, and the plant microbiome in microgravity. Research like this continues NASA’s efforts to grow food that is not only safe but also nutritious for astronauts living and working in the harsh environment of space. The ‘Outredgeous’ romaine lettuce variety was first grown aboard the space station in 2014, and Plant Habitat-07 builds on that legacy, using the station’s Advanced Plant Habitat to expand understanding of how plants adapt to spaceflight conditions. Findings from this work will support future long-duration missions to the Moon, Mars, and beyond, and could also lead to agricultural advances here on Earth.

4 min read May’s Night Sky Notes: How Do We Find Exoplanets? Astronomers have been trying to discover evidence that worlds exist around stars other than our Sun since the 19th century. By the mid-1990s, technology finally caught up with the desire for discovery and led to the first discovery of a planet orbiting another sun-like star, Pegasi 51b. Why did it take so long to discover these distant worlds, and what techniques do astronomers use to find them? The Transit Method A planet passing in front of its parent star creates a drop in the star’s apparent brightness, called a transit. Exoplanet Watch participants can look for transits in data from ground-based telescopes, helping scientists refine measurements of the length of a planet’s orbit around its star. Credit: NASA’s Ames Research Center One of the most famous exoplanet detection methods is the transit method, used by Kepler and other observatories. When a planet crosses in front of its host star, the light from the star dips slightly in brightness. Scientists can confirm a planet orbits its host star by repeatedly detecting these incredibly tiny dips in brightness using sensitive instruments. If you can imagine trying to detect the dip in light from a massive searchlight when an ant crosses in front of it, at a distance of tens of miles away, you can begin to see how difficult it can be to spot a planet from light-years away! Another drawback to the transit method is that the distant solar system must be at a favorable angle to our point of view here on Earth – if the distant system’s angle is just slightly askew, there will be no transits. Even in our solar system, a transit is very rare. For example, there were two transits of Venus visible across our Sun from Earth in this century. But the next time Venus transits the Sun as seen from Earth will be in the year 2117 – more than a century from the 2012 transit, even though Venus will have completed nearly 150 orbits around the Sun by then! The Wobble Method As a planet orbits a star, the star wobbles. This causes a change in the appearance of the star’s spectrum called Doppler shift. Because the change in wavelength is directly related to relative speed, astronomers can use Doppler shift to calculate exactly how fast an object is moving toward or away from us. Astronomers can also track the Doppler shift of a star over time to estimate the mass of the planet orbiting it. NASA, ESA, CSA, Leah Hustak (STScI) Spotting the Doppler shift of a star’s spectra was used to find Pegasi 51b, the first planet detected around a Sun-like star. This technique is called the radial velocity or “wobble” method. Astronomers split up the visible light emitted by a star into a rainbow. These spectra, and gaps between the normally smooth bands of light, help determine the elements that make up the star. However, if there is a planet orbiting the star, it causes the star to wobble ever so slightly back and forth. This will, in turn, cause the lines within the spectra to shift ever so slightly towards the blue and red ends of the spectrum as the star wobbles slightly away and towards us. This is caused by the blue and red shifts of the star’s light. By carefully measuring the amount of shift in the star’s spectra, astronomers can determine the size of the object pulling on the host star and if the companion is indeed a planet. By tracking the variation in this periodic shift of the spectra, they can also determine the time it takes the planet to orbit its parent star. Direct Imaging Finally, exoplanets can be revealed by directly imaging them, such as this image of four planets found orbiting the star HR 8799! Space telescopes use instruments called coronagraphs to block the bright light from the host star and capture the dim light from planets. The Hubble Space Telescope has captured images of giant planets orbiting a few nearby systems, and the James Webb Space Telescope has only improved on these observations by uncovering more details, such as the colors and spectra of exoplanet atmospheres, temperatures, detecting potential exomoons, and even scanning atmospheres for potential biosignatures! NASA’s James Webb Space Telescope has provided the clearest look in the infrared yet at the iconic multi-planet system HR 8799. The closest planet to the star, HR 8799 e, orbits 1.5 billion miles from its star, which in our solar system would be located between the orbit of Saturn and Neptune. The furthest, HR 8799 b, orbits around 6.3 billion miles from the star, more than twice Neptune’s orbital distance. Colors are applied to filters from Webb’s NIRCam (Near-Infrared Camera), revealing their intrinsic differences. A star symbol marks the location of the host star HR 8799, whose light has been blocked by the coronagraph. In this image, the color blue is assigned to 4.1 micron light, green to 4.3 micron light, and red to the 4.6 micron light. NASA, ESA, CSA, STScI, W. Balmer (JHU), L. Pueyo (STScI), M. Perrin (STScI) You can find more information and activities on NASA’s Exoplanets page, such as the Eyes on Exoplanets browser-based program, The Exoplaneteers, and some of the latest exoplanet news. Lastly, you can find more resources in our News & Resources section, including a clever demo on how astronomers use the wobble method to detect planets! The future of exoplanet discovery is only just beginning, promising rich rewards in humanity’s understanding of our place in the Universe, where we are from, and if there is life elsewhere in our cosmos.

Curiosity captured the image using its Left Navigation Camera on April 27, 2025 — Sol 4523, or Martian day 4,523 of the Mars Science Laboratory mission — at 13:23:32 UTC. NASA/JPL-Caltech Written by Lucy Lim, Planetary Scientist at NASA Goddard Space Flight Center Earth planning date: Monday, April 28, 2025 Curiosity is back on the road! For sols 4525 and 4526, we have an isolated nominal plan in which the communication pass timing works out in such a way that the rover can fit in fully targeted science blocks on both sols rather than just the first sol. So in this power-hungry Martian winter season, we’re in a good position to take advantage of the power saved up during the missed uplink. The weekend drive went well and delivered the rover into a stable, arm-work-compatible position in a workspace with rock targets that we could brush with the DRT. Happy days! The DRT/APXS/MAHLI measurements will bring us geochemical and rock texture data from local bedrock blocks “Bradshaw Trail” and “Sweetwater River.” Further geochemical information will come from the ChemCam LIBS rasters on a more coarsely layered target, “Breeze Hill,” and an exposed layer expressing both polygonal features and a vein or coating of dark-toned material, “Laguna Mountain.” Long-distance imaging with the ChemCam RMI included a mosaic to add to our coverage of the boxwork sedimentary features of the type Curiosity will soon be exploring in situ. A second RMI mosaic was planned to cover a truncated sedimentary horizon on the Texoli butte that may provide further evidence of ancient aeolian scouring events. Meanwhile, the “Morrell Potrero” Mastcam mosaic will provide some detail on the base of the boxwork-bearing “Ghost Mountain” butte and on a ridge nearby. In the drive direction, the “Garnet Peak” mosaic will capture some potentially new rock textures and colors in the upcoming strata. Nearer-field imaging in the plan includes Mastcam documentation of some troughs that provide evidence for sand and dust movement in response to the modern aeolian environment. Additionally Mastcam mosaics went to “Breeze Hill” (covering the LIBS target) and “Live Oak” to document variations in bedding, color, and texture in the nearby bedrock. A few observations of the modern environment were scheduled for the afternoon: a phase function sky survey to look for scattered light from thin water-ice clouds and a separate set of cloud altitude observations. Finally, a Mastcam documentation image was planned for the AEGIS LIBS target from the weekend plan! This reflects an update to the rover’s capability in which the AEGIS target can be determined and downlinked in time for the decisional downlink pass, so that we know where to look for it during the next planning cycle.

The impact of supporting STEM education extends far beyond the classroom, shaping the future of innovation and exploration. NASA Engages is the agency’s outreach website that connects NASA experts and resources with communities, educators, and students across the country. Led by NASA’s Office of STEM Engagement, the platform fosters collaboration between educators, organizations, and NASA employees to inspire the next generation. Giovanna Camacho, Pathways systems engineering intern from NASA’s Armstrong Flight Research Center in Edwards, California, teaches students about aeronautics during Aero Fair at Tropico Middle School in Rosamond, California, on April 9, 2025.NASA/Genaro Vavuris Bringing NASA to the Classroom NASA employees dedicate their time and expertise through NASA Engages, whether they’re passionate about robotics, flight research, or inspiring young minds to pursue STEM careers. One example of this is Aero Fair, a STEM program led by the California Office of STEM Engagement at NASA’s Armstrong Flight Research Center in Edwards, California. This initiative brings aeronautics directly to students, with NASA Armstrong professionals visiting classrooms – both in person and virtually – to engage students during three-day experiences that allow them to learn about aeronautics, meet NASA professionals, and explore potential career paths they might not have previously considered. “When volunteers step up to help inspire and facilitate learning in the classroom, they are benefiting not only the students they interact with, but our future generation as well,” says Giovanna Camacho, Pathways systems engineering intern at NASA Armstrong, who volunteered at the event. Chloe Day, a student at Tropico Middle School in Rosamond, California, said Aero Fair inspired her to consider a STEM career. “When NASA employees were talking about what they do and how they help our world today, it made me feel like I want to do it too.” Educators can request an Aero Fair experience through NASA’s STEM Gateway. These programs “give students a chance to see themselves as real problem-solvers and innovators,” said Shauna Tinich, a Tropico Middle School teacher. “The most beneficial part of Aero Fair is the real-world connection to STEM. The connection to NASA makes it real and exciting for the students.” Students from Tropico Middle School in Rosamond, California, build their own paper planes as part of a project during NASA Aero Fair on April 9, 2025.NASA/Genaro Vavuris A Program for Impact The NASA Engages website matches outreach opportunities to employee skills and interests, while educators and community organizations can use the website to request public speakers, classroom visits, and educational support at events. For many volunteers, the experience is just as inspiring as it is for the students. “Every time I volunteer, I walk out inspired,” Camacho said. “It motivates me to continue my pursuit of making a difference.” Gary Laier, center liaison for the Small Business Innovation Research and Small Business Technology Transfer programs at NASA Armstrong, and Aero Fair volunteer, agreed: “It’s a rewarding experience for students, teachers, and NASA volunteers alike. I enjoy the opportunity to inspire youth and get them excited about their futures.” By participating in outreach activities like Aero Fair, career panels, or events, NASA employees not only help ignite curiosity and provide knowledge to students and the community but also strengthen NASA’s connection to the communities it serves.

Did you know some of the brightest sources of light in the sky come from the regions around black holes in the centers of galaxies? It sounds a little contradictory, but it’s true! They may not look bright to our eyes, but satellites have spotted oodles of them across the universe. One of those satellites is NASA’s Fermi Gamma-ray Space Telescope. Fermi has found thousands of these kinds of galaxies since it launched in 2008, and there are many more out there! To view this video please enable JavaScript, and consider upgrading to a web browser that supports HTML5 video Watch a cosmic gamma-ray fireworks show in this animation using just a year of data from the Large Area Telescope (LAT) aboard NASA’s Fermi Gamma-ray Space Telescope. Each object’s magenta circle grows as it brightens and shrinks as it dims. The yellow circle represents the Sun following its apparent annual path across the sky. The animation shows a subset of the LAT gamma-ray records available for more than 1,500 objects in a continually updated repository. Over 90% of these sources are a type of galaxy called a blazar, powered by the activity of a supermassive black hole. NASA’s Marshall Space Flight Center/Daniel Kocevski Black holes are regions of space that have so much gravity that nothing — not light, not particles, nada — can escape. Most galaxies have supermassive black holes at their centers, and these black holes are hundreds of thousands to billions of times the mass of our Sun. In active galactic nuclei (also called “AGN” for short, or just “active galaxies”) the central region is stuffed with gas and dust that’s constantly falling toward the black hole. As the gas and dust fall, they start to spin and form a disk. Because of the friction and other forces at work, the spinning disk starts to heat up. This composite view of the active galaxy Markarian 573 combines X-ray data (blue) from NASA’s Chandra X-ray Observatory and radio observations (purple) from the Karl G. Jansky Very Large Array in New Mexico with a visible light image (gold) from the Hubble Space Telescope. Markarian 573 is an active galaxy that has two cones of emission streaming away from the supermassive black hole at its center. X-ray: NASA/CXC/SAO/A.Paggi et al; Optical: NASA/STScI; Radio: NSF/NRAO/VLA The disk’s heat gets emitted as light, but not just wavelengths of it that we can see with our eyes. We detect light from AGN across the entire electromagnetic spectrum, from the more familiar radio and optical waves through to the more exotic X-rays and gamma rays, which we need special telescopes to spot. In the heart of an active galaxy, matter falling toward a supermassive black hole creates jets of particles traveling near the speed of light as shown in this artist’s concept. NASA/Goddard Space Flight Center Conceptual Image Lab About one in 10 AGN beam out jets of energetic particles, which are traveling almost as fast as light. Scientists are studying these jets to try to understand how black holes — which pull everything in with their huge amounts of gravity — somehow provide the energy needed to propel the particles in these jets. This artist’s concept shows two views of the active galaxy TXS 0128+554, located around 500 million light-years away. Left: The galaxy’s central jets appear as they would if we viewed them both at the same angle. The black hole, embedded in a disk of dust and gas, launches a pair of particle jets traveling at nearly the speed of light. Scientists think gamma rays (magenta) detected by NASA’s Fermi Gamma-ray Space Telescope originate from the base of these jets. As the jets collide with material surrounding the galaxy, they form identical lobes seen at radio wavelengths (orange). The jets experienced two distinct bouts of activity, which created the gap between the lobes and the black hole. Right: The galaxy appears in its actual orientation, with its jets tipped out of our line of sight by about 50 degrees. NASA’s Goddard Space Flight Center Many of the ways we tell one type of AGN from another depend on how they’re oriented from our point of view. With radio galaxies, for example, we see the jets from the side as they’re beaming vast amounts of energy into space. Then there’s blazars, which are a type of AGN that have a jet that is pointed almost directly at Earth, which makes the AGN particularly bright. Blazar 3C 279’s historic gamma-ray flare in 2015 can be seen in this image from the Large Area Telescope on NASA’s Fermi satellite. During the flare, the blazar outshone the Vela pulsar, usually the brightest object in the gamma-ray sky. NASA/DOE/Fermi LAT Collaboration Fermi has been searching the sky for gamma ray sources since 2008. More than half of the sources it has found have been blazars. Gamma rays are useful because they can tell us a lot about how particles accelerate and how they interact with their environment. So why do we care about AGN? We know that some AGN formed early in the history of the universe. With their enormous power, they almost certainly affected how the universe changed over time. By discovering how AGN work, we can understand better how the universe came to be the way it is now.

Este artículo es para estudiantes de 5.o a 8.o grado. Cada vez que un astronauta sale de un vehículo espacial, se dice que hace una actividad extravehicular (EVA, por sus siglas en inglés). A esto también se le llama caminata espacial. El astronauta ruso Alexei Leonov hizo la primera caminata espacial el 18 de marzo de 1965. La primera caminata espacial duró 10 minutos. El astronauta Ed White hizo la primera caminata espacial de un estadounidense durante la misión Géminis 4, el 3 de junio de 1965. La caminata espacial de White duró 23 minutos. Hoy en día, las caminatas espaciales se hacen en el exterior de la Estación Espacial Internacional (EEI). Las caminatas espaciales suelen durar entre cinco y ocho horas, según el trabajo a realizar. El récord mundial de más caminatas espaciales lo tiene el cosmonauta ruso Anatoly Solovyev. Hizo 16 caminatas espaciales por un total de más de 82 horas en el espacio exterior. Cuatro astronautas de la NASA tienen un empate para la mayor cantidad de caminatas espaciales. Michael López-Alegría (Mike L.A.), Peggy Whitson, Bob Behnken y Chris Cassidy han hecho 10 caminatas espaciales cada uno. Mike L.A. tiene el récord de Estados Unidos para la mayor cantidad de tiempo en caminatas espaciales. Su total es de más de 67 horas. ¿Por qué los astronautas llevan a cabo caminatas espaciales? Los astronautas hacen caminatas espaciales por muchas razones. Las caminatas espaciales permiten a los astronautas trabajar fuera de su nave espacial mientras aún están en el espacio. Un trabajo que hacen los astronautas en una caminata espacial son los experimentos científicos. Se pueden sujetar experimentos en el exterior de una nave espacial para ver cómo el entorno espacial afecta diferentes objetos. Los astronautas colocan los experimentos fuera de la nave espacial durante una caminata espacial. Vuelven a salir para recuperar los experimentos cuando terminan. Los astronautas también pueden poner a prueba nuevos equipos y reparar los satélites o sus naves espaciales mientras están en órbita. Al hacer caminatas espaciales, los astronautas pueden reparar equipos que, de otro modo, tendrían que ser devueltos a la Tierra para su reparación. _____________________________________________________________________________ Palabras que debes saber radiación: una forma de energía que se emite, o transmite, en forma de rayos, ondas electromagnéticas o partículas _____________________________________________________________________________ ¿Cómo hacen los astronautas las caminatas espaciales? Cuando los astronautas hacen caminatas espaciales, usan trajes espaciales. Los trajes espaciales los protegen del duro entorno del espacio. Protegen a los astronautas de las temperaturas extremas de calor y frío, del dañino polvo espacial y de la radiación. Los trajes espaciales también les dan a los astronautas oxígeno para respirar y agua para beber durante las caminatas espaciales. Los astronautas se visten con sus trajes espaciales varias horas antes de hacer una caminata espacial. Los trajes están presurizados. Esto significa que los trajes están llenos de oxígeno. Los trajes espaciales están presurizados para mantener los fluidos del cuerpo en estado líquido. Una vez que tienen puestos sus trajes, los astronautas respiran oxígeno al 100% durante varias horas hasta que todo el nitrógeno sale de su cuerpo. Tener nitrógeno en el cuerpo durante una caminata espacial puede hacer que se formen burbujas de gas en el cuerpo. Estas burbujas de gas pueden hacer que los astronautas sientan dolor en articulaciones como los hombros, los codos, las muñecas y las rodillas. Esta condición se llama “enfermedad de los buzos” o síndrome de descompresión. La misma condición puede afectar a los buceadores que usan tanques de oxígeno para respirar debajo del agua. Los astronautas ahora están listos para salir de la nave espacial. Salen de la nave espacial a través de una puerta especial llamada compuerta de aire. La compuerta de aire tiene dos puertas. Cuando los astronautas están dentro de la nave espacial, la compuerta de aire es hermética, lo que significa que no puede salir el aire. Cuando los astronautas se preparan para salir a una caminata espacial, pasan por la primera puerta y la cierran herméticamente detrás de ellos. Luego pueden abrir la segunda puerta sin que el aire se escape de la nave espacial. Después de una caminata espacial, los astronautas regresan al interior a través de la compuerta de aire. Cuando un astronauta se quita el traje espacial, se dice que sale del traje. Los astronautas usan pasamanos en la estación espacial para desplazarse de un lugar a otro. A veces, se usa un gran brazo robótico para mover a los astronautas en las caminatas espaciales. Los astronautas están sujetos al brazo robótico con una correa para los pies. Los astronautas ahora están listos para salir de la nave espacial. Salen de la nave espacial por una puerta especial llamada compuerta de aire. La compuerta de aire tiene dos puertas. Cuando los astronautas están dentro de la nave espacial, la compuerta de aire es hermética, lo que significa que no puede salir el aire. Cuando los astronautas se preparan para salir a una caminata espacial, pasan por la primera puerta y la cierran herméticamente detrás de ellos. Luego pueden abrir la segunda puerta sin que el aire se salga de la nave espacial. Después de una caminata espacial, los astronautas regresan al interior a través de la compuerta de aire. ¿Cómo se mantienen seguros los astronautas durante las caminatas espaciales? Cuando hacen una caminata espacial, los astronautas usan correas de seguridad para sujetarse a su nave espacial. Las correas son como cuerdas. Un extremo está enganchado al caminante espacial. El otro extremo está conectado al vehículo. Las correas de seguridad evitan que los astronautas se alejen flotando en el espacio. Los astronautas también usan correas para evitar que las herramientas se alejen flotando. Atan las herramientas a sus trajes espaciales con correas. Otra forma en que los astronautas se mantienen seguros durante las caminatas espaciales es usando una mochila llamada SAFER. SAFER son las siglas en inglés de Ayuda Simplificada para Rescate en Actividad Extravehicular. El SAFER se usa como una mochila. Utiliza pequeños propulsores a reacción para permitir que el astronauta se desplace por el espacio. Si un astronauta se soltara y se alejara flotando, SAFER le ayudaría a volar de regreso a la nave espacial. Los astronautas controlan SAFER con una pequeña palanca de mando. ¿Cómo entrenan los astronautas para las caminatas espaciales? Una forma en que los astronautas se entrenan para las caminatas espaciales es nadando. Flotar en el espacio es muy parecido a flotar en el agua. Los astronautas practican las caminatas espaciales debajo del agua en una gran piscina cerca del Centro Espacial Johnson de la NASA en Houston, Texas. La piscina se llama Laboratorio de Flotabilidad Neutral (NBL, por sus siglas en inglés). La piscina tiene capacidad para unos 23,5 millones de litros (6,2 millones de galones) de agua. Por cada hora que pasen en una caminata espacial, los astronautas deben entrenar siete horas en la piscina del NBL. Otra forma en que los astronautas practican para una caminata espacial es utilizando la realidad virtual. Los astronautas usan un casco que tiene una pantalla de video dentro y guantes especiales. En la pantalla dentro del casco se muestra un video de la simulación. Los guantes especiales permiten mostrar los movimientos de los astronautas con el video. La simulación de realidad virtual se ve y se siente como una caminata espacial. Read this article in English here: What Is a Spacewalk?

Crew members are kicking off operations for several biological experiments that recently launched to the International Space Station aboard NASA’s 32nd SpaceX commercial resupply services mission. These include examining how microgravity affects production of protein by microalgae, testing a microscope to capture microbial activity, and studying genetic activity in biofilms. Microalgae in microgravity Sophie’s BioNutrients This ice cream is one of several products made with a protein powder created from Chorella microalgae by researchers for the SOPHONSTER investigation, which looks at whether the stress of microgravity affects the algae’s protein yield. Microalgae are nutrient dense and produce proteins with essential amino acids, beneficial fatty acids, B vitamins, iron, and fiber. These organisms also can be used to make fuel, cooking oil, medications, and materials. Learning more about microalgae growth and protein production in space could support development of sustainable alternatives to meat and dairy. Such alternatives could provide a food source on future space voyages and for people on Earth and be used to make biofuels and bioactive compounds in medicines. Microscopic motion Portland State University These swimming microalgae are visible thanks to the Extant Life Volumetric Imaging System or ELVIS, a fluorescent 3D imaging microscope that researchers are testing aboard the International Space Station. The investigation studies both active behaviors and genetic changes of microscopic algae and marine bacteria in response to spaceflight. ELVIS is designed to autonomously capture microscopic motion in 3D, a capability not currently available on the station. The technology could be useful for a variety of research in space and on Earth, such as monitoring water quality and detecting potentially infectious organisms. Genetics of biofilms BioServe This preflight image shows sample chambers for the Genetic Exchange in Microgravity for Biofilm Bioremediation (GEM-B2) investigation, which examines the mechanisms of gene transfer within biofilms under microgravity conditions. Biofilms are communities of microorganisms that collect and bind to a surface. They can clog and foul water systems, often leave a residue that can cause infections, and may become resistant to antibiotics. Researchers could use results from this work to develop genetic manipulations that inhibit biofilm formation, helping to maintain crew health and safety aboard the International Space Station and on future missions.

NASA/JPL-Caltech Written by Deborah Padgett, OPGS Task Lead at NASA’s Jet Propulsion Laboratory Earth planning date: Friday, April 25, 2025 On Sols 4520 and 4521, Curiosity was supposed to study layered rocks in its workspace, then drive on. Unfortunately, a communications pass didn’t go as expected, preventing this plan from being transmitted. Our rover is fine, but it has been metaphorically “twiddling its thumbs” waiting for the expected Wednesday contact from Earth. This is a process known as “runout,” which happens when Earth fails to call a spacecraft at the appointed time. The communications stations are back up now, so the team assembled a weekend plan made from Wednesday’s postponed activities plus an extra day of untargeted science observations after the drive. The additional two days prior to plan execution allowed our science team to add another interesting target to contact science at the starting location. On Sol 4522, Curiosity will start science observations with a Mastcam 14 x 3 mosaic on the new target “Mesa Peak,” a flat-topped, layered outcrop named for a mountain in the Santa Monica Mountains of Southern California covered with sandstone pinnacles and offering an ocean view toward Channel Islands National Park. This will be followed by two Mastcam examinations of troughs to document evidence of differential ground motion. ChemCam will then shine its laser on the “Fan Palm” nodular rock to determine its surface composition. Its telescopic RMI camera will then image distant “Torote Bowl.” After a set of REMS observations, Curiosity will un-stow its arm and begin a detailed study of “Hale Telescope,” a finely layered stone with a target name honoring the famous 200-inch telescope (5.1 meters) on Palomar Mountain, northeast of San Diego. Despite being close to 80 years old, Palomar Observatory’s Hale Telescope still enables world-class astronomy with teams from Caltech and its partner organizations competing for observing time every year. Here, 5,500 feet “up on the roof” (thank you, Carole King!) of Southern California is where I spent some of my happiest times in graduate school. Curiosity’s arm will first deploy the APXS to touch “Hale Telescope.” Then, the MAHLI microscopic imager will take extreme close-up pictures of this rock and the neighboring “Cerro Alto” target. Finally, APXS will measure the composition of “Hale Telescope” in a measurement lasting two hours, similar to the exposure time required for the actual 200-inch telescope to measure the redshift of quasars, determining that they were located at cosmological distances. Sol 4522 ends with Curiosity stowing its arm in preparation for the next sol’s drive. On 4523, Curiosity will perform Mastcam mosaics of “Puerto Suelo” and “Potrero Seco,” as well as companion observation of the ChemCam target “Fan Palm” and an AEGIS-selected target from Sol 4919. ChemCam will then use laser spectroscopy to obtain surface composition of “Mesa Peak” and train the RMI telescope on intriguing formations along the side of Texoli Butte. Mastcam will follow up with an “after the laser zap” picture of “Mesa Peak.” The science block ends with a Navcam 360-degree dust-devil survey. Afterwards, Curiosity will drive around 20 meters (about 66 feet), passing near or over some large rocks, followed by post-drive imaging with the Hazcams, Navcam, and Mastcam. Afterwards, the rover will do AEGIS observations and take a MARDI picture of the ground underneath the rover. On Sol 4524, the science block will focus on the atmosphere, with a super horizon cloud movie, a dust-devil survey, and Mastcam dust opacity observation. There will also be ChemCam laser spectroscopy of a target selected by AEGIS. Early on the morning of Sol 4525, Curiosity will wake to take a morning-light mosaic of the “boxwork” formations to the west with Navcam, then turn Navcam toward the sky for suprahorizon and zenith cloud movies and a dust opacity observation across Gale Crater. Mastcam will then perform its own dust observation, which will wrap up the plan. If the team finds that Curiosity’s wheels are firmly seated on Martian soil and not rocks, our rover will again do contact science on a new set of rocks and continue its journey toward the boxwork formation.

8 Min Read How to Contribute to Citizen Science with NASA A number of NASA projects use mobile phone apps to put satellite data into the palm of your hand, and allow intrepid citizen scientists to upload data. Credits: NASA A cell phone, a computer—and your curiosity—is all you need to become a NASA citizen scientist and contribute to projects about Earth, the solar system, and beyond. Science is built from small grains of sand, and you can contribute yours from any corner of the world. All you need is a cell phone or a computer with an internet connection to begin a scientific adventure. Can you imagine making a pioneering discovery in the cosmos? Want to help solve problems that could improve life on our planet? Or maybe you dream of helping solve an ancient mystery of the universe? All of this is possible through NASA’s Citizen Science program. NASA defines citizen science, or participatory science, as “science projects that rely on volunteers,” said Dr. Marc Kuchner, an astrophysicist and the Citizen Science Officer in the agency’s Science Mission Directorate in Washington, D.C. For decades, volunteers have been supporting NASA researchers in different fields and in a variety of ways, depending on the project. They help by taking measurements, sorting data from NASA missions, and deepening our understanding of the universe and our home planet. It all counts. “That’s science for you: It’s collaborative,” said Kuchner, who oversees the more than 30 citizen science projects NASA offers. “I connect the public and scientists to get more NASA science done.” NASA astrophysicist Marc Kuchner is a pioneer in participatory science and today serves as NASA’s Citizen Science program officer. In 2014, Kuchner created the Disk Detective project, which helps NASA scientists study how planets form. Kuchner has also been the principal investigator for some of the agency’s many citizen science projects, but today he oversees the portfolio and promotes volunteer participation around the world. Credit: David Friedlander A menu of projects for all tastes Citizen scientists can come from anywhere in the world—they do not have to be U.S. citizens or residents. Volunteers help NASA look for planets in other solar systems, called exoplanets; sort clouds in Earth’s sky; observe solar eclipses; or detect comets and asteroids. Some of those space rocks are even named after the volunteers who helped find them. Mass participation is key in initiatives that require as many human eyes as possible. “There are science projects that you can’t do without the help of a big team,” Kuchner said. For example, projects that need large datasets from space telescopes—or “things that are physically big and you need people in different places looking from different angles,” he said. One example is Aurorasaurus, which invites people to observe and classify northern and southern auroras. “We try to study them with satellites, but it really helps to have people on the ground taking photos from different places at different times,” he explained. “Part of the way we serve our country and humankind is by sharing not just the pretty pictures from our satellites, but the entire experience of doing science,” Kuchner said. More than 3 million people have participated in the program. Kuchner believes that shows how much people want to be part of what he calls the “roller coaster” of science. “They want to go on that adventure with us, and we are thrilled to have them.” The dream of discovering “You can help scientists who are now at NASA and other organizations around the world to discover interesting things,” said Faber Burgos, a citizen scientist and science communicator from Colombia. “Truth be told, I’ve always dreamed of making history.” Colombian citizen scientist Faber Burgos studied Modern Languages at the Colombian School of Industrial Careers and has a university degree in Classical Archaeology. Today, he is dedicated to disseminating science content through his social media accounts, focusing on children. In 2020, he and his team launched a balloon probe into the stratosphere with a camera that captured the curvature of the Earth, with the aim of demonstrating that the Earth is round. The video of that feat exceeds 97 million views on his Facebook account, earning him a Guinness World Record. Credit: Courtesy of Faber Burgos Burgos has been involved in two projects for the past four years: the International Astronomical Search Collaboration (IASC), which searches the sky for potentially dangerous asteroids, and Backyard Worlds: Planet 9. This project uses data from NASA’s now-completed Wide-field Infrared Survey Explorer (WISE) and its follow-up mission, NEOWISE, to search for brown dwarfs and a hypothetical ninth planet. “There are really amazing participants in this project,” said Kuchner, who helped launch it in 2015. NASA’s WISE and NEOWISE missions detected about 2 billion sources in the sky. “So, the question is: Among those many sources, are any of them new unknowns?” he said. The project has already found more than 4,000 brown dwarfs. These are Jupiter-sized objects—balls of gas that are too big to be planets, but too small to be stars. Volunteers have even helped discover a new type of brown dwarf. Participants in the project are also hopeful they’ll find a hypothetical ninth planet, possibly Neptune-sized, in an orbit far beyond Pluto. The Backyard Worlds: Planet 9 citizen science project asks volunteers to help search for new objects at the edge of our solar system. The assignment is to review images from NASA’s past WISE and NEOWISE missions in search of two types of astronomical objects: brown dwarfs(balls of gas the same size as Jupiter that have too little mass to be considered stars) and low-mass stars. Or, even, the hypothetical ninth planet of our Sun, known as Planet nine, or Planet X. The image shows an artist’s rendering of such a hypothetical world orbiting far from the Sun. Credit: Caltech/R. Hurt (IPAC) Caltech/R. Hurt (IPAC) Burgos explained that analyzing the images is easy. “If it’s a moving object, it’s obviously going to be something of interest,” he said. “Usually, when you see these images, everything is still. But if there’s an object moving, you have to keep an eye on it.” Once a citizen scientist marks the object across the full image sequence, they send the information to NASA scientists to evaluate. “As a citizen scientist, I’m happy to do my bit and, hopefully, one day discover something very interesting,” he said. “That’s the beauty of NASA—it invites everyone to be a scientist. Here, it doesn’t matter what you are, but your desire to learn.” The first step To become a NASA citizen scientist, start by visiting the program’s website. There you’ll find a complete list of available projects with links to their respective sites. Some are available in Spanish and other languages. Many projects are also hosted on the Zooniverse platform, which has been available since 2006. “Another cool way to get involved is to come to one of our live events,” said Kuchner. These are virtual events open to the public, where NASA scientists present their projects and invite people to participate. “Pick a project you like—and if it’s not fun, pick a different one,” he advised. “There are wonderful relationships to be had if you reach out to scientists and other participants.” Another way for people to get involved in citizen science is to participate in the annual NASA International Space Apps Challenge, the largest global hackathon. This two-day event creates innovation through international collaboration, providing an opportunity for participants to use NASA’s free and open data and agency partners’ space-based data to tackle real-world problems on Earth and in space. The next NASA International Space Apps Challenge will be October 4-5, 2025. Credit: NASA Age is not the limit People of all ages can be citizen scientists. Some projects are kid-friendly, such as Nemo-Net, an iPad game that invites participants to color coral reefs to help sort them. “I’d like to encourage young people to start there—or try a project with one of the older people in their life,” Kuchner said. Citizen science can also take place in classrooms. In the Growing Beyond Earth project, teachers and students run experiments on how to grow plants in space for future missions. The IASC project also works with high schools to help students detect asteroids. A student waters small plants inside a Growing Beyond Earth citizen science project grow box. Credit: NASA Projects by the community, for the community GLOBE Observer is another initiative with an international network of teachers and students. The platform offers a range of projects—many in Spanish—that invite people to collect data using their cell phones. One of the most popular is the GLOBE Mosquito Habitat Mapper, which tracks the migration and spread of mosquitoes that carry diseases. “It’s a way to help save lives—tracking the vectors that transmit malaria and Zika, among others,” Kuchner said. Other GLOBE projects explore everything from ground cover to cloud types. Some use astronomical phenomena visible to everyone. For example, during the 2024 total solar eclipse, participants measured air temperature using their phones and shared that data with NASA scientists. The full experience of doing science No prior studies are needed, but many volunteers go on to collaborate on—or even lead—scientific research. More than 500 NASA citizen scientists have co-authored scientific publications. One of them is Hugo Durantini Luca, from Córdoba, Argentina, who has participated in 17 published articles, with more on the way. For years, he explored various science projects, looking for one where he could contribute more actively. Durantini Luca participated in one of NASA’s first citizen science projects, launched in 2006: Stardust at home. Still ongoing, this project invites volunteers to participate in the search for evidence of interstellar dust on the aerogel and aluminum foil collectors returned by NASA’s Stardust mission, using an online virtual microscope. Credit: NASA He participated in NASA’s first citizen science project, Stardust@home, which invites users to search for interstellar dust particles in collectors from the Stardust mission, using a virtual microscope. In 2014, he discovered Disk Detective, a project that searches for disks around stars, where planets may form. By looking at images from the WISE and NEOWISE missions, participants can help understand how worlds are born and how solar systems evolve. “And, incidentally, if we find planets or some sign of life, all the better,” said Durantini Luca. Although that remains a dream, they have made other discoveries—like a new kind of stellar disk called the “Peter Pan Disk,” which appears young even though the star it surrounds is not. Durantini Luca participated in one of NASA’s first citizen science projects, launched in 2006: Stardust at home. Still ongoing, this project invites volunteers to participate in the search for evidence of interstellar dust on the aerogel and aluminum foil collectors returned by NASA’s Stardust mission, using an online virtual microscope. Credit: NASA Science in person In 2016, Durantini Luca got the chance to support Disk Detective with his own observations from the southern hemisphere. He traveled to El Leoncito Astronomical Complex (CASLEO), an observatory in San Juan, Argentina. There, he learned to use a spectrograph—an instrument that breaks down starlight to analyze its composition. He treasures that experience. “Curiously, it was the first time in my life I used a telescope,” he said. In 2016, citizen scientist Hugo Durantini Luca traveled for 18 hours to the El Leoncito Astronomical Complex (CASLEO), at the foot of the Andes Mountains. From there, he made observations of a candidate star of the Disk Detective project. Credit: Luciano García While in-person opportunities are rare, both virtual and physical events help build community. Citizen scientists stay in touch weekly through various channels. “Several of us are friends already—after so many years of bad jokes on calls,” said Durantini Luca. “People send me pictures of how they met,” said Kuchner. He said the program has even changed how he does science. “It’s changed my life,” he said. “Science is already cool—and this makes it even cooler.” About the Author NASA Science Editorial Team Share Details Last Updated Apr 29, 2025 Related Terms Citizen Science Earth Science Get Involved The Solar System The Universe Explore More 3 min read Help Classify Galaxies Seen by NASA’s James Webb Space Telescope!

Landing on the Moon is not easy, particularly when a crew or spacecraft must meet exacting requirements. For Artemis missions to the lunar surface, those requirements include an ability to land within an area about as wide as a football field in any lighting condition amid tough terrain. NASA’s official lunar landing requirement is to be able to land within 50 meters (164 feet) of the targeted site and developing precision tools and technologies is critically important to mission success. NASA engineers recently took a major step toward safe and precise landings on the Moon – and eventually Mars and icy worlds – with a successful field test of hazard detection technology at NASA’s Kennedy Space Center Shuttle Landing Facility in Florida. A joint team from the Aeroscience and Flight Mechanics Division at NASA’s Johnson Space Center’s in Houston and Goddard Space Flight Center in Greenbelt, Maryland, achieved this huge milestone in tests of the Goddard Hazard Detection Lidar from a helicopter at Kennedy in March 2025. NASA’s Hazard Detection Lidar field test team at Kennedy Space Center’s Shuttle Landing Facility in Florida in March 2025. NASA The new lidar system is one of several sensors being developed as part of NASA’s Safe & Precise Landing – Integrated Capabilities Evolution (SPLICE) Program, a Johnson-managed cross-agency initiative under the Space Technology Mission Directorate to develop next-generation landing technologies for planetary exploration. SPLICE is an integrated descent and landing system composed of avionics, sensors, and algorithms that support specialized navigation, guidance, and image processing techniques. SPLICE is designed to enable landing in hard-to-reach and unknown areas that are of potentially high scientific interest. The lidar system, which can map an area equivalent to two football fields in just two seconds, is a crucial program component. In real time and compensating for lander motion, it processes 15 million short pulses of laser light to quickly scan surfaces and create real-time, 3D maps of landing sites to support precision landing and hazard avoidance. Those maps will be read by the SPLICE Descent and Landing Computer, a high-performance multicore computer processor unit that analyzes all SPLICE sensor data and determines the spacecraft’s velocity, altitude, and terrain hazards. It also computes the hazards and determines a safe landing location. The computer was developed by the Avionics Systems Division at Johnson as a platform to test navigation, guidance, and flight software. It previously flew on Blue Origin’s New Shepard booster rocket. The NASA team prepares the Descent and Landing Computer for Hazard Detection Lidar field testing at Kennedy Space Center. NASA For the field test at Kennedy, Johnson led test operations and provided avionics and guidance, navigation, and control support. Engineers updated the computer’s firmware and software to support command and data interfacing with the lidar system. Team members from Johnson’s Flight Mechanics branch also designed a simplified motion compensation algorithm and NASA’s Jet Propulsion Laboratory in Southern California contributed a hazard detection algorithm, both of which were added to the lidar software by Goddard. Support from NASA contractors Draper Laboratories and Jacobs Engineering played key roles in the test’s success. Primary flight test objectives were achieved on the first day of testing, allowing the lidar team time to explore different settings and firmware updates to improve system performance. The data confirmed the sensor’s capability in a challenging, vibration-heavy environment, producing usable maps. Preliminary review of the recorded sensor data shows excellent reconstruction of the hazard field terrain. A Hazard Detection Lidar scan of a simulated hazard field at Kennedy Space Center (left) and a combined 3D map identifying roughness and slope hazards. NASA Beyond lunar applications, SPLICE technologies are being considered for use on Mars Sample Return, the Europa Lander, Commercial Lunar Payload Services flights, and Gateway. The DLC design is also being evaluated for potential avionics upgrades on Artemis systems. Additionally, SPLICE is supporting software tests for the Advancement of Geometric Methods for Active Terrain Relative Navigation (ATRN) Center Innovation Fund project, which is also part of Johnson’s Aeroscience and Flight Mechanics Division. The ATRN is working to develop algorithms and software that can use data from any active sensor – one measuring signals that were reflected, refracted, or scattered by a body’s surface or its atmosphere – to accurately map terrain and provide absolute and relative location information. With this type of system in place, spacecraft will not need external lighting sources to find landing sites. With additional suborbital flight tests planned through 2026, the SPLICE team is laying the groundwork for safer, more autonomous landings on the Moon, Mars, and beyond. As NASA prepares for its next era of exploration, SPLICE will be a key part of the agency’s evolving landing, guidance, and navigation capabilities.

ESA/Hubble & NASA, L. C. Ho, D. Thilker Today’s rather aquatic-themed NASA/ESA Hubble Space Telescope image features the spiral galaxy Messier 77, also known as the Squid Galaxy, which sits 45 million light-years away in the constellation Cetus (The Whale). The designation Messier 77 comes from the galaxy’s place in the famous catalog compiled by the French astronomer Charles Messier. Another French astronomer, Pierre Méchain, discovered the galaxy in 1780. Both Messier and Méchain were comet hunters who cataloged nebulous objects that could be mistaken for comets. Messier, Méchain, and other astronomers of their time mistook the Squid Galaxy for either a spiral nebula or a star cluster. This mischaracterization isn’t surprising. More than a century would pass between the discovery of the Squid Galaxy and the realization that the ‘spiral nebulae’ scattered across the sky were not part of our galaxy but were in fact separate galaxies millions of light-years away. The Squid Galaxy’s appearance through a small telescope — an intensely bright center surrounded by a fuzzy cloud — closely resembles one or more stars wreathed in a nebula. The name ‘Squid Galaxy’ is recent, and stems from the extended, filamentary structure that curls around the galaxy’s disk like the tentacles of a squid. The Squid Galaxy is a great example of how advances in technology and scientific understanding can completely change our perception of an astronomical object — and even what we call it! Hubble previously released an image of M77 in 2013. This new image incorporates recent observations made with different filters and updated image processing techniques which allow astronomers to see the galaxy in more detail. View the full article

6 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) JunoCam, the visible light imager aboard NASA’s Juno, captured this enhanced-color view of Ju-piter’s northern high latitudes from an altitude of about 36,000 miles (58,000 kilometers) above the giant planet’s cloud tops during the spacecraft’s 69th flyby on Jan. 28, 2025. Image data: NASA/JPL-Caltech/SwRI/MSSS Image processing: Jackie Branc (CC BY) New data from the agency’s Jovian orbiter sheds light on the fierce winds and cyclones of the gas giant’s northern reaches and volcanic action on its fiery moon. NASA’s Juno mission has gathered new findings after peering below Jupiter’s cloud-covered atmosphere and the surface of its fiery moon, Io. Not only has the data helped develop a new model to better understand the fast-moving jet stream that encircles Jupiter’s cyclone-festooned north pole, it’s also revealed for the first time the subsurface temperature profile of Io, providing insights into the moon’s inner structure and volcanic activity. Team members presented the findings during a news briefing in Vienna on Tuesday, April 29, at the European Geosciences Union General Assembly. “Everything about Jupiter is extreme. The planet is home to gigantic polar cyclones bigger than Australia, fierce jet streams, the most volcanic body in our solar system, the most powerful aurora, and the harshest radiation belts,” said Scott Bolton, principal investigator of Juno at the Southwest Research Institute in San Antonio. “As Juno’s orbit takes us to new regions of Jupiter’s complex system, we’re getting a closer look at the immensity of energy this gas giant wields.” To view this video please enable JavaScript, and consider upgrading to a web browser that supports HTML5 video Made with data from the JIRAM instrument aboard NASA’s Juno, this animation shows the south polar region of Jupiter’s moon Io during a Dec. 27, 2024, flyby. The bright spots are locations with higher temperatures caused by volcanic activity; the gray areas resulted when Io left the field of view.NASA/JPL/SwRI/ASI – JIRAM Team (A.M.) Lunar Radiator While Juno’s microwave radiometer (MWR) was designed to peer beneath Jupiter’s cloud tops, the team has also trained the instrument on Io, combining its data with Jovian Infrared Auroral Mapper (JIRAM) data for deeper insights. “The Juno science team loves to combine very different datasets from very different instruments and see what we can learn,” said Shannon Brown, a Juno scientist at NASA’s Jet Propulsion Laboratory in Southern California. “When we incorporated the MWR data with JIRAM’s infrared imagery, we were surprised by what we saw: evidence of still-warm magma that hasn’t yet solidified below Io’s cooled crust. At every latitude and longitude, there were cooling lava flows.” The data suggests that about 10% of the moon’s surface has these remnants of slowly cooling lava just below the surface. The result may help provide insight into how the moon renews its surface so quickly as well as how as well as how heat moves from its deep interior to the surface. “Io’s volcanos, lava fields, and subterranean lava flows act like a car radiator,” said Brown, “efficiently moving heat from the interior to the surface, cooling itself down in the vacuum of space.” Looking at JIRAM data alone, the team also determined that the most energetic eruption in Io’s history (first identified by the infrared imager during Juno’s Dec. 27, 2024, Io flyby) was still spewing lava and ash as recently as March 2. Juno mission scientists believe it remains active today and expect more observations on May 6, when the solar-powered spacecraft flies by the fiery moon at a distance of about 55,300 miles (89,000 kilometers). This composite image, derived from data collected in 2017 by the JIRAM instrument aboard NASA’s Juno, shows the central cyclone at Jupiter’s north pole and the eight cy-clones that encircle it. Data from the mission indicates these storms are enduring fea-tures.NASA/JPL-Caltech/SwRI/ASI/INAF/JIRAM Colder Climes On its 53rd orbit (Feb 18, 2023), Juno began radio occultation experiments to explore the gas giant’s atmospheric temperature structure. With this technique, a radio signal is transmitted from Earth to Juno and back, passing through Jupiter’s atmosphere on both legs of the journey. As the planet’s atmospheric layers bend the radio waves, scientists can precisely measure the effects of this refraction to derive detailed information about the temperature and density of the atmosphere. So far, Juno has completed 26 radio occultation soundings. Among the most compelling discoveries: the first-ever temperature measurement of Jupiter’s north polar stratospheric cap reveals the region is about 11 degrees Celsius cooler than its surroundings and is encircled by winds exceeding 100 mph (161 kph). Polar Cyclones The team’s recent findings also focus on the cyclones that haunt Jupiter’s north. Years of data from the JunoCam visible light imager and JIRAM have allowed Juno scientists to observe the long-term movement of Jupiter’s massive northern polar cyclone and the eight cyclones that encircle it. Unlike hurricanes on Earth, which typically occur in isolation and at lower latitudes, Jupiter’s are confined to the polar region. By tracking the cyclones’ movements across multiple orbits, the scientists observed that each storm gradually drifts toward the pole due to a process called “beta drift” (the interaction between the Coriolis force and the cyclone’s circular wind pattern). This is similar to how hurricanes on our planet migrate, but Earthly cyclones break up before reaching the pole due to the lack of warm, moist air needed to fuel them, as well as the weakening of the Coriolis force near the poles. What’s more, Jupiter’s cyclones cluster together while approaching the pole, and their motion slows as they begin interacting with neighboring cyclones. “These competing forces result in the cyclones ‘bouncing’ off one another in a manner reminiscent of springs in a mechanical system,” said Yohai Kaspi, a Juno co-investigator from the Weizmann Institute of Science in Israel. “This interaction not only stabilizes the entire configuration, but also causes the cyclones to oscillate around their central positions, as they slowly drift westward, clockwise, around the pole.” The new atmospheric model helps explain the motion of cyclones not only on Jupiter, but potentially on other planets, including Earth. “One of the great things about Juno is its orbit is ever-changing, which means we get a new vantage point each time as we perform a science flyby,” said Bolton. “In the extended mission, that means we’re continuing to go where no spacecraft has gone before, including spending more time in the strongest planetary radiation belts in the solar system. It’s a little scary, but we’ve built Juno like a tank and are learning more about this intense environment each time we go through it.” More About Juno NASA’s Jet Propulsion Laboratory, a division of Caltech in Pasadena, California, manages the Juno mission for the principal investigator, Scott Bolton, of the Southwest Research Institute in San Antonio. Juno is part of NASA’s New Frontiers Program, which is managed at NASA’s Marshall Space Flight Center in Huntsville, Alabama, for the agency’s Science Mission Directorate in Washington. The Italian Space Agency funded the Jovian InfraRed Auroral Mapper. Lockheed Martin Space in Denver built and operates the spacecraft. Various other institutions around the U.S. provided several of the other scientific instruments on Juno.

Intuitive Machines’ IM-2 captured an image March 6, 2025, after landing in a crater from the Moon’s South Pole. The lunar lander is on its side near the intended landing site, Mons Mouton. In the center of the image between the two lander legs is the Polar Resources Ice Mining Experiment 1 suite, which shows the drill deployed.Intuitive Machines NASA’s PRIME-1 (Polar Resources Ice Mining Experiment 1) mission was designed to demonstrate technologies to help scientists better understand lunar resources ahead of crewed Artemis missions to the Moon. During the short-lived mission on the Moon, the performance of PRIME-1’s technology gave NASA teams reason to celebrate. “The PRIME-1 mission proved that our hardware works in the harshest environment we’ve ever tested it in,” said Janine Captain, PRIME-1 co-principal investigator and research chemist at NASA’s Kennedy Space Center in Florida. “While it may not have gone exactly to plan, this is a huge step forward as we prepare to send astronauts back to the Moon and build a sustainable future there.” Intuitive Machines’ IM-2 mission launched to the Moon on Feb. 26, 2025, from NASA Kennedy’s Launch Complex 39A, as part of the company’s second Moon delivery for NASA under the agency’s CLPS (Commercial Lunar Payload Services) initiative and Artemis campaign. The IM-2 Nova-C lunar lander, named Athena, carried PRIME-1 and its suite of two instruments: a drill known as TRIDENT (The Regolith and Ice Drill for Exploring New Terrain), designed to bring lunar soil to the surface; and a mass spectrometer, Mass Spectrometer Observing Lunar Operations (MSOLO), to study TRIDENT’s drill cuttings for the presence of gases that could one day help provide propellant or breathable oxygen to future Artemis explorers. The IM-2 mission touched down on the lunar surface on March 6, just around 1,300 feet (400 meters) from its intended landing site of Mons Mouton, a lunar plateau near the Moon’s South Pole. The Athena lander was resting on its side inside a crater preventing it from recharging its solar cells, resulting in an end of the mission. “We were supposed to have 10 days of operation on the Moon, and what we got was closer to 10 hours,” said Julie Kleinhenz, NASA’s lead systems engineer for PRIME-1, as well as the in-situ resource utilization system capability lead deputy for the agency. “It was 10 hours more than most people get so I am thrilled to have been a part of it.” Kleinhenz has spent nearly 20 years working on how to use lunar resources for sustained operations. In-situ resource utilization harnesses local natural resources at mission destinations. This enables fewer launches and resupply missions and significantly reduces the mass, cost, and risk of space exploration. With NASA poised to send humans back to the Moon and on to Mars, generating products for life support, propellants, construction, and energy from local materials will become increasingly important to future mission success. “In-situ resource utilization is the key to unlocking long-term exploration, and PRIME-1 is helping us lay this foundation for future travelers.” Captain said. The PRIME-1 technology also set out to answer questions about the properties of lunar regolith, such as soil strength. This data could help inform the design of in-situ resource utilization systems that would use local resources to create everything from landing pads to rocket fuel during Artemis and later missions. “Once we got to the lunar surface, TRIDENT and MSOLO both started right up, and performed perfectly. From a technology demonstrations standpoint, 100% of the instruments worked.” Kleinhenz said. The lightweight, low-power augering drill built by Honeybee Robotics, known as TRIDENT, is 1 meter long and features rotary and percussive actuators that convert energy into the force needed to drill. The drill was designed to stop at any depth as commanded from the ground and deposit its sample on the surface for analysis by MSOLO, a commercial off-the-shelf mass spectrometer modified by engineers and technicians at NASA Kennedy to withstand the harsh lunar environment. Designed to measure the composition of gases in the vicinity of the lunar lander, both from the lander and from the ambient exosphere, MSOLO can help NASA analyze the chemical makeup of the lunar soil and study water on the surface of the Moon. Once on the Moon, the actuators on the drill performed as designed, completing multiple stages of movement necessary to drill into the lunar surface. Prompted by commands from technicians on Earth, the auger rotated, the drill extended to its full range, the percussion system performed a hammering motion, and the PRIME-1 team turned on an embedded core heater in the drill and used internal thermal sensors to monitor the temperature change. While MSOLO was able to perform several scans to detect gases, researchers believe from the initial data that the gases detected were all anthropogenic, or human in origin, such as gases vented from spacecraft propellants and traces of Earth water. Data from PRIME-1 accounted for some of the approximately 7.5 gigabytes of data collected during the IM-2 mission, and researchers will continue to analyze the data in the coming months and publish the results.
