NASA, ESA, CSA, STScI, Chris Willott (National Research Council Canada), Lamiya Mowla (Wellesley College), Kartheik Iyer (Columbia University) For the first time, NASA’s James Webb Space Telescope has detected and “weighed” a galaxy that not only existed around 600 million years after the big bang, but is also similar to what our Milky Way galaxy’s mass might have been at the same stage of development. Other galaxies Webb has detected at this time period are significantly more massive. Nicknamed the Firefly Sparkle, this galaxy is gleaming with star clusters — 10 in all — each of which researchers examined in great detail.

For the first time, astronomers using NASA’s James Webb Space Telescope have identified a galaxy, nicknamed the Firefly Sparkle, that not only is in the process of assembling and forming stars around 600 million years after the big bang, but also weighs about the same as our Milky Way galaxy if we could “wind back the clock” to weigh it as it developed. Two companion galaxies are close by, which may ultimately affect how this galaxy forms and builds mass over billions of years. NASA, ESA, CSA, STScI, Chris Willott (National Research Council Canada), Lamiya Mowla (Wellesley College), Kartheik Iyer (Columbia University) “I didn’t think it would be possible to resolve a galaxy that existed so early in the universe into so many distinct components, let alone find that its mass is similar to our own galaxy’s when it was in the process of forming,” said Lamiya Mowla, co-lead author of the paper and an assistant professor at Wellesley College in Massachusetts. “There is so much going on inside this tiny galaxy, including so many different phases of star formation.”
Webb was able to image the galaxy in crisp detail for two reasons. One is a benefit of the cosmos: A massive foreground galaxy cluster radically enhanced the distant galaxy’s appearance through a natural effect known as gravitational lensing. And when combined with the telescope’s specialization in high-resolution infrared light, Webb delivered unprecedented new data about the galaxy’s contents.
Image B: Galaxy Cluster MACS J1423 (NIRCam Image)
In this image from NASA’s James Webb Space Telescope, thousands of glimmering galaxies are bound together by their own gravity, making up a massive cluster formally classified as MACS J1423. The largest, bright white oval is a supergiant elliptical galaxy. The galaxy cluster acts like a lens, magnifying and distorting the light of objects that lie well behind it, an effect known as gravitational lensing. NASA, ESA, CSA, STScI, Chris Willott (National Research Council Canada), Lamiya Mowla (Wellesley College), Kartheik Iyer (Columbia University) “Without the benefit of this gravitational lens, we would not be able to resolve this galaxy,” said Kartheik Iyer, co-lead author and NASA Hubble Fellow at Columbia University in New York. “We knew to expect it based on current physics, but it’s surprising that we actually saw it.”
Mowla, who spotted the galaxy in Webb’s image, was drawn to its gleaming star clusters, because objects that sparkle typically indicate they are extremely clumpy and complicated. Since the galaxy looks like a “sparkle” or swarm of lightning bugs on a warm summer night, they named it the Firefly Sparkle galaxy.
Reconstructing the Galaxy’s Appearance
The research team modeled what the galaxy might have looked like if it weren’t stretched and discovered that it resembled an elongated raindrop. Suspended within it are two star clusters toward the top and eight toward the bottom. “Our reconstruction shows that clumps of actively forming stars are surrounded by diffuse light from other unresolved stars,” said Iyer. “This galaxy is literally in the process of assembling.”
Webb’s data shows the Firefly Sparkle galaxy is on the smaller side, falling into the category of a low-mass galaxy. Billions of years will pass before it builds its full heft and a distinct shape. “Most of the other galaxies Webb has shown us aren’t magnified or stretched, and we are not able to see their ‘building blocks’ separately. With Firefly Sparkle, we are witnessing a galaxy being assembled brick by brick,” Mowla said.
Stretched Out and Shining, Ready for Close Analysis
Since the galaxy is warped into a long arc, the researchers easily picked out 10 distinct star clusters, which are emitting the bulk of the galaxy’s light. They are represented here in shades of pink, purple, and blue. Those colors in Webb’s images and its supporting spectra confirmed that star formation didn’t happen all at once in this galaxy, but was staggered in time.
“This galaxy has a diverse population of star clusters, and it is remarkable that we can see them separately at such an early age of the universe,” said Chris Willott from the National Research Council of Canada’s Herzberg Astronomy and Astrophysics Research Centre, a co-author and the observation program’s principal investigator. “Each clump of stars is undergoing a different phase of formation or evolution.”
The galaxy’s projected shape shows that its stars haven’t settled into a central bulge or a thin, flattened disk, another piece of evidence that the galaxy is still forming.

‘Glowing’ Companions
Researchers can’t predict how this disorganized galaxy will build up and take shape over billions of years, but there are two galaxies that the team confirmed are “hanging out” within a tight perimeter and may influence how it builds mass over billions of years.
Firefly Sparkle is only 6,500 light-years away from its first companion, and its second companion is separated by 42,000 light-years. For context, the fully formed Milky Way is about 100,000 light-years across — all three would fit inside it. Not only are its companions very close, the researchers also think that they are orbiting one another.
Each time one galaxy passes another, gas condenses and cools, allowing new stars to form in clumps, adding to the galaxies’ masses. “It has long been predicted that galaxies in the early universe form through successive interactions and mergers with other tinier galaxies,” said Yoshihisa Asada, a co-author and doctoral student at Kyoto University in Japan. “We might be witnessing this process in action.”
The team’s research relied on data from Webb’s CAnadian NIRISS Unbiased Cluster Survey (CANUCS), which includes near-infrared images from NIRCam (Near-Infrared Camera) and spectra from the microshutter array aboard NIRSpec (Near-Infrared Spectrograph). The CANUCS data intentionally covered a field that NASA’s Hubble Space Telescope imaged as part of its Cluster Lensing And Supernova survey with Hubble (CLASH) program.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA’s Ingenuity Mars Helicopter, right, stands near the apex of a sand ripple in an image taken by Perseverance on Feb. 24, 2024, about five weeks after the rotorcraft’s final flight. Part of one of Ingenuity’s rotor blades lies on the surface about 49 feet (15 meters) west of helicopter (at left in image).NASA/JPL-Caltech/LANL/CNES/CNRS The review takes a close look the final flight of the agency’s Ingenuity Mars Helicopter, which was the first aircraft to fly on another world.
Engineers from NASA’s Jet Propulsion Laboratory in Southern California and AeroVironment are completing a detailed assessment of the Ingenuity Mars Helicopter’s final flight on Jan. 18, 2024, which will be published in the next few weeks as a NASA technical report. Designed as a technology demonstration to perform up to five experimental test flights over 30 days, Ingenuity was the first aircraft on another world. It operated for almost three years, performed 72 flights, and flew more than 30 times farther than planned while accumulating over two hours of flight time.
The investigation concludes that the inability of Ingenuity’s navigation system to provide accurate data during the flight likely caused a chain of events that ended the mission. The report’s findings are expected to benefit future Mars helicopters, as well as other aircraft destined to operate on other worlds.

NASA’s Ingenuity Mars Helicopter used its black-and-white navigation camera to capture this video on Feb. 11, 2024, showing the shadow of its rotor blades. The imagery confirmed damage had occurred during Flight 72. NASA/JPL-Caltech Final Ascent
Flight 72 was planned as a brief vertical hop to assess Ingenuity’s flight systems and photograph the area. Data from the flight shows Ingenuity climbing to 40 feet (12 meters), hovering, and capturing images. It initiated its descent at 19 seconds, and by 32 seconds the helicopter was back on the surface and had halted communications. The following day, the mission reestablished communications, and images that came down six days after the flight revealed Ingenuity had sustained severe damage to its rotor blades.
What Happened
“When running an accident investigation from 100 million miles away, you don’t have any black boxes or eyewitnesses,” said Ingenuity’s first pilot, Håvard Grip of JPL. “While multiple scenarios are viable with the available data, we have one we believe is most likely: Lack of surface texture gave the navigation system too little information to work with.”
The helicopter’s vision navigation system was designed to track visual features on the surface using a downward-looking camera over well-textured (pebbly) but flat terrain. This limited tracking capability was more than sufficient for carrying out Ingenuity’s first five flights, but by Flight 72 the helicopter was in a region of Jezero Crater filled with steep, relatively featureless sand ripples.
This short animation depicts a NASA concept for a proposed follow-on to the agency’s Ingenuity Mars Helicopter called Mars Chopper, which remains in early conceptual and design stages. In addition to scouting, such a helicopter could carry science instruments to study terrain rovers can’t reach. One of the navigation system’s main requirements was to provide velocity estimates that would enable the helicopter to land within a small envelope of vertical and horizontal velocities. Data sent down during Flight 72 shows that, around 20 seconds after takeoff, the navigation system couldn’t find enough surface features to track.
Photographs taken after the flight indicate the navigation errors created high horizontal velocities at touchdown. In the most likely scenario, the hard impact on the sand ripple’s slope caused Ingenuity to pitch and roll. The rapid attitude change resulted in loads on the fast-rotating rotor blades beyond their design limits, snapping all four of them off at their weakest point — about a third of the way from the tip. The damaged blades caused excessive vibration in the rotor system, ripping the remainder of one blade from its root and generating an excessive power demand that resulted in loss of communications.
This graphic depicts the most likely scenario for the hard landing of NASA’s Ingenuity Mars Helicopter during its 72nd and final flight on Jan. 18, 2024. High horizontal velocities at touchdown resulted in a hard impact on a sand ripple, which caused Ingenuity to pitch and roll, damaging its rotor blades. NASA/JPL-Caltech Down but Not Out
Although Flight 72 permanently grounded Ingenuity, the helicopter still beams weather and avionics test data to the Perseverance rover about once a week. The weather information could benefit future explorers of the Red Planet. The avionics data is already proving useful to engineers working on future designs of aircraft and other vehicles for the Red Planet.
“Because Ingenuity was designed to be affordable while demanding huge amounts of computer power, we became the first mission to fly commercial off-the-shelf cellphone processors in deep space,” said Teddy Tzanetos, Ingenuity’s project manager. “We’re now approaching four years of continuous operations, suggesting that not everything needs to be bigger, heavier, and radiation-hardened to work in the harsh Martian environment.”
Inspired by Ingenuity’s longevity, NASA engineers have been testing smaller, lighter avionics that could be used in vehicle designs for the Mars Sample Return campaign. The data is also helping engineers as they research what a future Mars helicopter could look like — and do.
During a Wednesday, Dec. 11, briefing at the American Geophysical Union’s annual meeting in Washington, Tzanetos shared details on the Mars Chopper rotorcraft, a concept that he and other Ingenuity alumni are researching. As designed, Chopper is approximately 20 times heavier than Ingenuity, could fly several pounds of science equipment, and autonomously explore remote Martian locations while traveling up to 2 miles (3 kilometers) in a day. (Ingenuity’s longest flight was 2,310 feet, or 704 meters.)
“Ingenuity has given us the confidence and data to envision the future of flight at Mars,” said Tzanetos.

If Digital Transformation were a ship, the vessel for delivering on our missions and ensuring smooth passage into the future, our final Digital Transformer of 2024 would be the captain. Growing up sailing with her father on the Chesapeake Bay, this transformer developed the navigation skills she now uses at NASA “with both clarity and precision, much like a sailor who understands the subtle shifts in the wind,” says Christina Haymes, DT Enterprise Integration Architect. “She knows how to watch the sea to find the invisible breeze,” notes Patrick Murphy, DT Portfolio Manager. “I admire how she operates as a leader both in calm and troubling seas to get us where we want to be.” Vision and leadership are just two of the many reasons why our December Digital Transformer, Jill Marlowe, stands at the helm of our ever-evolving journey.
Jill has dedicated over three decades to her career at NASA, starting as an engineer and evolving into her position as the Digital Transformation Officer. Her early sailing experiences led her to pursue ocean and aerospace engineering at Virginia Tech; an innate passion for continual growth led to subsequent master’s degrees in mechanical, civil, and environmental engineering. As Jill moved into leadership positions across NASA’s engineering organizations, divisions, and directorates, she realized that the technology she was instinctively using to transform her work could also help the agency overcome a wider range of challenges.
Her keen eye for cross-cutting solutions perfectly positioned her for the dynamic role of Digital Transformation Officer, diving into technical problems with engineers one day and strategizing with senior executives the next. Although she brings a rigorous technical background to the role, Jill most enjoys the creative and collaborative aspects. “It really gives me an opportunity to engage with a lot of earlier career folks who often are bringing some of these digital ideas into our workplace,” she says. “To me, it’s a very generative role, and that’s what I like the best about it.”
Jill commits to practicing what she preaches, strategically leveraging tools like Microsoft Teams and other M365 applications to build a culture of digital innovation and influence others to join the movement. Krista Kinnard, DT Culture and Communications Lead, says, “We work in a digital world with new tools that make our lives easier. Jill has really shown how the way we interact with each other matters and can be streamlined to drive our team to success.” Jill’s growth-oriented mindset drives her to stay on the cutting edge of new capabilities—always with the goal of enabling mission outcomes and increasing our capacity for partnership.
When times are challenging, people want heroes. I think a lot of what NASA does is bring humanity together.
Jill Marlowe
Digital Transformation Officer
Jill’s fervent belief in the power of collaboration is evident in the way she talks about her technical work, particularly with Digital Engineering (DE). “I am very excited about where we are with digital engineering at NASA and the progress Terry Hill and his team have made [toward] a unified engineering community,” says Jill. Through seed funding and ongoing support, Jill and the DT team grew Digital Engineering at NASA from initial prototype tests to an operationalized program within the Office of the Chief Engineer. In addition to the community’s alignment around a shared vision, Jill is proud of the team’s quantitative achievements in developing systems, tools, and approaches for digitalizing the engineering processes and adopting a common toolchain. “I feel like we’ve been talking about those kinds of ideas my entire career, and we’re this close to having this in the hands of the engineers across NASA so they can work together and with our partners in ways that we haven’t been able to before”
For Jill, the measure of DT’s success lies in the ability to enable more complex missions, collaborate more seamlessly with partners, and build more resilient systems that prepare us for the future. Under her leadership, DT facilitated the maturation of NASA Mission Cloud, a digital solution for capturing mission capability requirements and defining technology needs. In FY24, DT launched the new IT Modernization for Transformation (ITMX) fund and curated a $10M portfolio of enterprise solutions in data interoperability, federated search, digital engineering, cybersecurity, artificial intelligence, and more. By championing Digital Transformation at NASA and demonstrating its value, Jill paved the way for solutions that accelerate discovery and mission delivery.
Over her career, Jill forged bonds, championed innovation, and positioned the agency to leverage the ripple effects of her work long after her upcoming retirement in December. Her legacy, however, might be best summarized by the way she made people feel. “It sounds simple, but so many people are listening to respond, whereas Jill is listening to understand,” Krista says. The rest of DT leadership echoes this sentiment. “Jill has a deep knowledge of NASA and has built strong relationships across the agency. Most of all, I value her mentorship and friendship,” says Christina. Patrick puts it simply: “Collaborating with Jill is a joy.”
As she reflects on her time at the agency, Jill shares inspiring aspirations for NASA’s future and DT’s ability to carry us on that voyage. “When times are challenging, people want heroes. I think a lot of what NASA does is bring humanity together. When I think about those big expectations on NASA for the future and the technology that’s coming along that can make those dreams come true…it literally gives me chills.” She continues, “I encourage the continued community around Digital Transformation, the continued quest to find shared solutions to common challenges. Because I really do think that’s the way we’re going to get there from here.”

NASA will host a media teleconference at 1 p.m. EST Tuesday, Dec. 17, to discuss the agency science and technology flying aboard Firefly Aerospace’s first delivery to the Moon as part of the NASA’s CLPS (Commercial Lunar Payload Services) initiative and Artemis campaign.
Audio of the call will livestream on the agency’s website at:
https://www.nasa.gov/live
Briefing participants include:
Joel Kearns, deputy associate administrator for exploration, Science Mission Directorate, NASA Headquarters Ryan Watkins, program scientist, Exploration Science Strategy and Integration Office, NASA Headquarters Jason Kim, chief executive officer, Firefly Aerospace
To participate by telephone, media must RSVP no later than two hours before the briefing to: ksc-newsroom@mail.nasa.gov.
Firefly’s Blue Ghost lunar lander will launch on a SpaceX Falcon 9 rocket from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. The six-day launch window opens no earlier than mid-January 2025.
The lunar mission, named Ghost Riders in the Sky, will land near a volcanic feature called Mons Latreille within Mare Crisium, a more than 300-mile-wide basin located in the northeast quadrant of the Moon’s near side. The mission will carry 10 NASA instruments and first-of-their-kind demonstrations to further our understanding of the Moon’s environment and help prepare for future human missions to the lunar surface, as part of the agency’s Moon to Mars exploration approach.
Science investigations on this flight include testing lunar subsurface drilling, regolith sample collection, global navigation satellite system abilities, radiation tolerant computing, and lunar dust mitigation. The data captured could also benefit humans on Earth by providing insights into how space weather and other cosmic forces impact Earth.
Under the CLPS model, NASA is investing in commercial delivery services to the Moon to enable industry growth and support long-term lunar exploration. As a primary customer for CLPS deliveries, NASA is to be one of many customers on future flights.
