A sideways spiral galaxy shines in this NASA/ESA Hubble Space Telescope image. Located about 60 million light-years away in the constellation Virgo (the Maiden), NGC 4388 is a resident of the Virgo galaxy cluster. This enormous cluster of galaxies contains more than a thousand members and is the nearest large galaxy cluster to the Milky Way.
NGC 4388 appears to tilt at an extreme angle relative to our point of view, giving us a nearly edge-on prospect of the galaxy. This perspective reveals a curious feature that wasn’t visible in a previous Hubble image of this galaxy released in 2016: a plume of gas from the galaxy’s nucleus, here seen billowing out from the galaxy’s disk toward the lower-right corner of the image. But where did this outflow come from, and why does it glow?
The answer likely lies in the vast stretches of space that separate the galaxies of the Virgo cluster. Though the space between galaxies appears empty, this space is occupied by hot wisps of gas called the intracluster medium. As NGC 4388 moves within the Virgo cluster, it plunges through the intracluster medium. Pressure from hot intracluster gas whisks away gas from within NGC 4388’s disk, causing it to trail behind as NGC 4388 moves.
The source of the ionizing energy that causes this gas cloud to glow is more uncertain. Researchers suspect that some of the energy comes from the center of the galaxy, where a supermassive black hole spins gas around it into a superheated disk. The blazing radiation from this disk might ionize the gas closest to the galaxy, while shock waves might be responsible for ionizing filaments of gas farther out.
This image incorporates new data, including several additional wavelengths of light, that bring the ionized gas cloud into view. The image holds data from several observing programs that aim to illuminate galaxies with active black holes at their centers.
Betelgeuse and the Crab Nebula: Stellar Death and Rebirth
This highly detailed image of the Crab Nebula was assembled by combining data from five telescopes spanning nearly the entire breadth of the electromagnetic spectrum: The Very Large Array (radio) in red; Spitzer Space Telescope (infrared) in yellow; Hubble Space Telescope (visible) in green; XMM-Newton (ultraviolet) in blue; and Chandra X-ray Observatory (X-ray) in purple.

What happens when a star dies? In 2019, Betelgeuse dimmed in brightness, sparking speculation that it may soon explode as a supernova. While it likely won’t explode quite yet, we can preview its fate by observing the nearby Crab Nebula.

Betelgeuse is easy to find as the red-hued shoulder star of Orion. A variable star, Betelgeuse, usually competes with the brilliant blue-white Rigel for the position of the brightest star in Orion. Betelgeuse is a young star, estimated to be a few million years old, but due to its giant size, it leads a fast and furious life. This massive star, known as a supergiant, exhausted the hydrogen fuel in its core and began to fuse helium instead, which caused the outer layers of the star to cool and swell dramatically in size. Betelgeuse is one of the few stars for which we have any detailed surface observations, due to its vast size – somewhere between the diameters of the orbits of Mars and Jupiter – and its relatively close distance of about 642 light-years. Betelgeuse is also a “runaway star,” with its remarkable speed possibly triggered by a merger with a smaller companion star. If that is the case, Betelgeuse may actually have millions of years left! So, Betelgeuse may not explode soon after all, or it might explode tomorrow! We have much more to learn about this intriguing star.

It is known as the expanding gaseous remnant from a star that self-detonated as a supernova, briefly shining as brightly as 400 million suns.

The Crab Nebula (M1) is relatively close to Betelgeuse in the sky, in the nearby constellation of Taurus. Its ghostly, spidery gas clouds result from a massive explosion; a supernova observed by astronomers in 1054! A backyard telescope allows you to see some details. Still, only advanced telescopes reveal the rapidly spinning neutron star found in its center: the last stellar remnant from that cataclysmic event. These gas clouds were created during the giant star’s violent demise and expand ever outward to enrich the universe with heavy elements like silicon, iron, and nickel. These element-rich clouds are like a cosmic fertilizer, making rocky planets like our own Earth possible. Supernovae also send out powerful shock waves that help trigger star formation. In fact, if it weren’t for a long-ago supernova, our solar system – along with all of us – wouldn’t exist!

European Space Agency (ESA) astronaut Thomas Pesquet removes the Protein Crystallization Facility hardware from an incubator aboard the International Space Station for the CASIS PCG-5 investigation, which crystallized a monoclonal antibody developed by Merck Research Labs.
NASA
NASA opens the International Space Station for scientists and researchers, inviting them to use the benefits of microgravity for private industry research, technology demonstrations, and more. Today, half of the crew’s time aboard station is devoted to these aims, including medical research that addresses complex health challenges on Earth and prepares astronauts for future deep space missions.
Supported by knowledge gained from space station experiments, researchers at Merck Research Labs received approval in September from the U.S. Food and Drug Administration for a new injectable version of a medication used to treat several types of early-stage cancers called pembrolizumab, also known by its brand name KEYTRUDA. The development of the injectable formula has been supported by research efforts aboard the space station through the ISS National Laboratory, resulting in reduced treatment times while maintaining its efficacy.
Originally, the treatment was delivered during an in-office visit via infusion therapy into the patient’s veins, a process that could take up to two hours. Initial delivery improvements reduced infusion times to less than 30 minutes every three weeks. The newly approved subcutaneous injectable form takes about one minute every three weeks, promising to reduce cost and significantly reduce treatment time for patients and healthcare providers.
UV imaging of a ground control sample (left) and spaceflight sample (right) from Merck’s research shows the much more uniform size and distribution of crystals grown in microgravity. These results helped researchers to refine ground-based production of uniform crystalline suspensions required for an injectable version of KEYTRUDA.
Merck
Since 2014, Merck has flown crystal growth experiments to the space station to better understand how crystals form, including the monoclonal antibody used in this cancer treatment. Monoclonal antibodies are lab-made proteins that help the body fight diseases. This research focused on producing crystalline suspensions that dissolve easily in liquid, making it possible to deliver the medication by injection. In microgravity, the absence of gravity’s physical forces allows scientists to grow larger, more uniform, and higher-quality crystals than those grown in ground-based labs, advancing medication development and structural modeling.
Research aboard the space station has provided valuable insights into how gravity influences crystallization, helping to improve drug formulations. The work of NASA and its partners aboard the space station improves lives on Earth, grows a commercial economy in low Earth orbit, and prepares for human exploration of the Moon and Mars.
Curiosity Blog, Sols 4743-4749: Polygons in the Hollow
NASA’s Mars rover Curiosity acquired this close-up image of polygon-shaped features in the “Monte Grande” boxwork hollow. Similar polygonal patterns in various strata were seen previously, elsewhere in Gale Crater. Curiosity captured the image using its Mars Hand Lens Imager (MAHLI), located on the turret at the end of the rover’s robotic arm, on Dec. 11, 2025 — Sol 4745, or Martian day 4,745 of the Mars Science Laboratory mission — at 16:55:37 UTC.

Earth Planning Date: Friday, Dec. 12, 2025
The weekend drive starting from the “Nevado Sajama” drill site brought Curiosity back into the “Monte Grande” boxwork hollow. We’ve been in this hollow before for the “Valle de la Luna” drill campaign, but now that the team has seen the results from both the “Valle de la Luna” and “Nevado Sajama” drilled samples, we’ve decided that there’s more work to do here.
Overall science goals here included analysis of the other well-exposed bedrock block in Monte Grande to improve our statistics on the composition of the bedrock in the hollows, and also high-resolution imaging and compositional analysis of portions of the walls of the hollow, other than those that had been covered during the Valle de la Luna campaign. These are part of a systematic mini-campaign to map a transect over the hollow-to-ridge structure from top to bottom at this site.
The post-drive imaging revealed a surprise — Valle de la Luna’s neighboring block was covered with polygons! As it turned out, the rover’s position during our previous visit for the Valle de la Luna drill campaign happened to have stood in the way of imaging of the polygonal features on this block so this was our first good look at them. We have seen broadly similar polygonal patterns in various strata in Gale Crater before — recently in the layered sulfate units (for instance, during Sols 4532-4533 and Sols 4370-4371) but we hadn’t seen them in the bottom of a boxwork hollow. Interestingly, this block looks more rubbly in texture than many of the previously observed polygon-covered blocks.
We’re interested in the relationship of the visibly protruding fracture-filling material here to fracture-filling materials seen in previous polygons, and also in the relationship of the polygonal surface on top to the more chaotic-appearing exposures lower on the block, and to the equivalent strata in the nearby wall of the hollow. We therefore planned a super-sized MAHLI mosaic that will support three-dimensional modeling of the upper and lower exposed surfaces of the polygon-bearing block. Several APXS and ChemCam LIBS observations targeted on the polygon centers and polygon ridges were also planned, to measure composition. Meanwhile, Mastcam has been busy planning stereo images of the nearby hollow wall in addition to the various blocks on the hollow floor.
The hollow also included freshly exposed light-toned material from where the rover had driven over and scuffed some bedrock, so another APXS measurement and a ChemCam LIBS went to the scuffed patch to measure the fresh surface.
We’ll be driving on Sol 4748. As we drive we’ll be taking a MARDI “sidewalk” observation, to image the ground beneath the rover as we approach the wall for a closer view, and hopefully some contact science in next week’s plans.

A graphic for the Moon Mascot: NASA Artemis II ZGI Design Challenge.
Freelancer
Whose Moon Mascot design will join the Artemis II astronauts on their historic voyage around the Moon in early 2026?
Between March 7 and Jun. 16, 2025, NASA worked with crowdsourcing company Freelancer to seek design ideas from global creators for a zero gravity indicator that will fly aboard the agency’s Artemis II test flight.
Zero gravity indicators are small, plush items carried aboard spacecraft to provide a visual indication of when the spacecraft and its crew reach space.
For the first eight minutes after liftoff, the crew and their indicator nearby will still be pushed into their seats by gravity, and the force of the climb into space. When the main engines of the SLS (Space Launch System) rocket’s core stage cut off, gravity’s restraints are lifted, but the crew will still be strapped safely into their seats – their zero gravity indicator’s ability to float will provide proof that they’ve made it into space.
Artemis II marks the first time that the public has had a hand in creating a crew’s mascot.
The Mission
Over the course of about ten days, four astronauts will travel approximately 685,000 miles from Earth, venture around the Moon, and return home. The flight will—for the first time with astronauts—test NASA’s human deep space exploration capabilities, including the agency’s Exploration Ground Systems, SLS (Space Launch System) rocket, and Orion spacecraft.
NASA has a long history of flying zero gravity indicators for human spaceflight missions. Many missions to the International Space Station include a plush item. A plush Snoopy rode inside Orion during NASA’s uncrewed Artemis I mission.
NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, and CSA (Canadian Space Agency) astronaut Jeremy Hansen will venture around the Moon and back. The mission is the first crewed flight under NASA’s Artemis campaign and is another step toward missions on the lunar surface and helping the agency prepare for future human missions to Mars.
The Contest
The Artemis II astronauts attended SXSW 2025 on March 7, 2025, and sat on a panel to discuss their upcoming mission around the Moon and answer questions from the audience. During the panel, commander Reid Wiseman showed the audience his zero gravity indicator from his Expedition 40 mission to the International Space Station. His zero gravity indicator was a toy giraffe named Giraffiti. Wiseman’s mother gifted Giraffiti to his oldest daughter when she was born. When Wiseman embarked on his first mission to space, his kids gave him Giraffiti to take with him to space.
“This little guy spent every day with me in my crew quarters,” said Wiseman. “It was a connection back home to my kids.”

NASA’s Hubble Sees Asteroids Colliding at Nearby Star for First Time
Like a game of cosmic bumper cars, scientists think the early days of our solar system were a time of violent turmoil, with planetesimals, asteroids, and comets smashing together and pelting the Earth, Moon, and the other inner planets with debris. Now, in a historical milestone, NASA’s Hubble Space Telescope has directly imaged similar catastrophic collisions in a nearby planetary system around another star, Fomalhaut.
“This is certainly the first time I’ve ever seen a point of light appear out of nowhere in an exoplanetary system,” said principal investigator Paul Kalas of the University of California, Berkeley. “It’s absent in all of our previous Hubble images, which means that we just witnessed a violent collision between two massive objects and a huge debris cloud unlike anything in our own solar system today. Amazing!”
Just 25 light-years from Earth, Fomalhaut is one of the brightest stars in the night sky. Located in the constellation Piscis Austrinus, also known as the Southern Fish, it is more massive and brighter than the Sun and is encircled by several belts of dusty debris.
This composite Hubble Space Telescope image shows the debris ring and dust clouds cs1 and cs2 around the star Fomalhaut. Fomalhaut itself is masked out to allow the fainter features to be seen. Its location is marked by the white star.

In 2008, scientists used Hubble to discover a candidate planet around Fomalhaut, making it the first stellar system with a possible planet found using visible light. That object, called Fomalhaut b, now appears to be a dust cloud masquerading as a planet—the result of colliding planetesimals. While searching for Fomalhaut b in recent Hubble observations, scientists were surprised to find a second point of light at a similar location around the star. They call this object “circumstellar source 2” or “cs2” while the first object is now known as “cs1.”
Tackling Mysteries of Colliding Planetesimals
Why astronomers are seeing both of these debris clouds so physically close to each other is a mystery. If the collisions between asteroids and planetesimals were random, cs1 and cs2 should appear by chance at unrelated locations. Yet, they are positioned intriguingly near each other along the inner portion of Fomalhaut’s outer debris disk.
Another mystery is why scientists have witnessed these two events within such a short timeframe. “Previous theory suggested that there should be one collision every 100,000 years, or longer. Here, in 20 years, we’ve seen two,” explained Kalas. “If you had a movie of the last 3,000 years, and it was sped up so that every year was a fraction of a second, imagine how many flashes you’d see over that time. Fomalhaut’s planetary system would be sparkling with these collisions.”
Collisions are fundamental to the evolution of planetary systems, but they are rare and difficult to study.
This artist’s concept shows the sequence of events leading up to the creation of dust cloud cs2 around the star Fomalhaut. In Panel 1, the star Fomalhaut appears in the top left corner. Two white dots, located in the bottom right corner, represent the two massive objects in orbit around Fomalhaut. In Panel 2, the objects approach each other. Panel 3 shows the violent collision of these two objects. In Panel 4, the resulting dust cloud cs2 becomes visible and starlight pushes the dust grains away from the star.

“The exciting aspect of this observation is that it allows researchers to estimate both the size of the colliding bodies and how many of them there are in the disk, information which is almost impossible to get by any other means,” said co-author Mark Wyatt at the University of Cambridge in England. “Our estimates put the planetesimals that were destroyed to create cs1 and cs2 at just 37 miles or 60 kilometers across, and we infer that there are 300 million such objects orbiting in the Fomalhaut system.”
“The system is a natural laboratory to probe how planetesimals behave when undergoing collisions, which in turn tells us about what they are made of and how they formed,” explained Wyatt.
Cautionary Tale
The transient nature of Fomalhaut cs1 and cs2 poses challenges for future space missions aiming to directly image exoplanets. Such telescopes may mistake dust clouds like cs1 and cs2 for actual planets.
“Fomalhaut cs2 looks exactly like an extrasolar planet reflecting starlight,” said Kalas. “What we learned from studying cs1 is that a large dust cloud can masquerade as a planet for many years. This is a cautionary note for future missions that aim to detect extrasolar planets in reflected light.”
Looking to Future
Kalas and his team have been granted Hubble time to monitor cs2 over the next three years. They want to see how it evolves—does it fade, or does it get brighter? Being closer to the dust belt than cs1, the expanding cs2 cloud is more likely to start encountering other material in the belt. This could lead to a sudden avalanche of more dust in the system, which could cause the whole surrounding area to get brighter.

“We will be tracing cs2 for any changes in its shape, brightness, and orbit over time,” said Kalas, “It’s possible that cs2 will start becoming more oval or cometary in shape as the dust grains are pushed outward by the pressure of starlight.”
The team also will use the NIRCam (Near-Infrared Camera) instrument on NASA’s James Webb Space Telescope to observe cs2. Webb’s NIRCam has the ability to provide color information that can reveal the size of the cloud’s dust grains and their composition. It can even determine if the cloud contains water ice.
Hubble and Webb are the only observatories capable of this kind of imaging. While Hubble primarily sees in visible wavelengths, Webb could view cs2 in the infrared. These different, complementary wavelengths are needed to provide a broad multi-spectral investigation and a more complete picture of the mysterious Fomalhaut system and its rapid evolution.
This research appears in the December 18 issue of Science.
The Hubble Space Telescope has been operating for over three decades and continues to make ground-breaking discoveries that shape our fundamental understanding of the universe. Hubble is a project of international cooperation between NASA and ESA (European Space Agency). NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages the telescope and mission operations. Lockheed Martin Space, based in Denver, also supports mission operations at Goddard. The Space Telescope Science Institute in Baltimore, which is operated by the Association of Universities for Research in Astronomy, conducts Hubble science operations for NASA.

The airliner you board in the future could look a lot different from today’s, with longer, thinner wings that provide a smoother ride while saving fuel.
Those wings would be a revolutionary design for commercial aircraft, but like any breakthrough technology, they come with their own development challenges – which experts from NASA and Boeing are now working to solve.
When creating lift, longer, thinner wings can reduce drag, making them efficient. However, they can become very flexible in flight.
Through their Integrated Adaptive Wing Technology Maturation collaboration, NASA and Boeing recently completed wind tunnel tests of a “higher aspect ratio wing model” looking for ways to get the efficiency gains without the potential issues these kinds of wings can experience.
“When you have a very flexible wing, you’re getting into greater motions,” said Jennifer Pinkerton, a NASA aerospace engineer at NASA Langley Research Center in Hampton, Virginia. “Things like gust loads and maneuver loads can cause even more of an excitation than with a smaller aspect ratio wing. Higher aspect ratio wings also tend to be more fuel efficient, so we’re trying to take advantage of that while simultaneously controlling the aeroelastic response.”
Take a minute to watch this video about the testing NASA and Boeing are doing on longer, narrower aircraft wings.
Without the right engineering, long, thin wings could potentially bend or experience a condition known as wing flutter, causing aircraft to vibrate and shake in gusting winds.
“Flutter is a very violent interaction,” Pinkerton said. “When the flow over a wing interacts with the aircraft structure and the natural frequencies of the wing are excited, wing oscillations are amplified and can grow exponentially, leading to potentially catastrophic failure. Part of the testing we do is to characterize aeroelastic instabilities like flutter for aircraft concepts so that in actual flight, those instabilities can be safely avoided.”
To help demonstrate and understand this, researchers from NASA and Boeing sought to soften the impacts of wind gusts on the aircraft, lessen the wing loads from aircraft turns and movements, and suppress wing flutter.
Reducing or controlling those factors can have a significant impact on an aircraft’s performance, fuel efficiency, and passenger comfort.
Testing for this in a controlled environment is impossible with a full-sized commercial airliner, as no wind tunnel could accommodate one.
However, NASA Langley’s Transonic Dynamics Tunnel, which has been contributing to the design of U.S. commercial transports, military aircraft, launch vehicles, and spacecraft for over 60 years, features a test section 16 feet high by 16 feet wide, big enough for large-scale models.
To shrink a full-size plane down to scale, NASA and Boeing worked with NextGen Aeronautics, which designed and fabricated a complex model resembling an aircraft divided down the middle, with one 13-foot wing.
Mounted to the wall of the wind tunnel, the model was outfitted with 10 control surfaces – moveable panels – along the wing’s rear edge. Researchers adjusted those control surfaces to control airflow and reduce the forces that were causing the wing to vibrate.
Instruments and sensors mounted inside the model measured the forces acting on the model, as well as the vehicle’s responses.

The model wing represented a leap in sophistication from a smaller one developed during a previous NASA-Boeing collaboration called the Subsonic Ultra Green Aircraft Research (SUGAR).
“The SUGAR model had two active control surfaces,” said Patrick S. Heaney, principal investigator at NASA for the Integrated Adaptive Wing Technology Maturation collaboration. “And now on this particular model we have ten. We’re increasing the complexity as well as expanding what our control objectives are.”
A first set of tests, conducted in 2024, gave experts baseline readings that they compared to NASA computational simulations, allowing them to refine their models. A second set of tests in 2025 used the additional control surfaces in new configurations.
The most visible benefits of these new capabilities appeared during testing to alleviate the forces from gusting winds, when researchers saw the wing’s shaking greatly reduced.
With testing completed, NASA and Boeing experts are analyzing data and preparing to share their results with the aviation community. Airlines and original equipment manufacturers can learn and benefit from the lessons learned, deciding which to apply to the next generation of aircraft.
“Initial data analyses have shown that controllers developed by NASA and Boeing and used during the test demonstrated large performance improvements,” Heaney said. “We’re excited to continue analyzing the data and sharing results in the months to come.”
NASA’s Advanced Air Transport Technology project works to advance aircraft design and technology under the agency’s Advanced Air Vehicles program, which studies, evaluates, and develops technologies and capabilities for new aircraft systems. The project and program fall within NASA’s Aeronautics Research Mission Directorate.
What can we do to help aircraft wings perform better in flight, creating a smoother, more fuel efficient, and safer experience for travelers? This is a quest...

Launched in March, NASA’s SPHEREx space telescope has completed its first infrared map of the entire sky in 102 colors. While not visible to the human eye, these 102 infrared wavelengths of light are prevalent in the cosmos, and observing the entire sky this way enables scientists to answer big questions, including how a dramatic event that occurred in the first billionth of a trillionth of a trillionth of a second after the big bang influenced the 3D distribution of hundreds of millions of galaxies in our universe. In addition, scientists will use the data to study how galaxies have changed over the universe’s nearly 14 billion-year history and learn about the distribution of key ingredients for life in our own galaxy.
“It’s incredible how much information SPHEREx has collected in just six months — information that will be especially valuable when used alongside our other missions’ data to better understand our universe,” said Shawn Domagal-Goldman, director of the Astrophysics Division at NASA Headquarters in Washington. “We essentially have 102 new maps of the entire sky, each one in a different wavelength and containing unique information about the objects it sees. I think every astronomer is going to find something of value here, as NASA’s missions enable the world to answer fundamental questions about how the universe got its start, and how it changed to eventually create a home for us in it.”
Circling Earth about 14½ times a day, SPHEREx (which stands for Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer) travels from north to south, passing over the poles. Each day it takes about 3,600 images along one circular strip of the sky, and as the days pass and the planet moves around the Sun, SPHEREx’s field of view shifts as well. After six months, the observatory has looked out into space in every direction, capturing the entire sky in 360 degrees.
Managed by NASA’s Jet Propulsion Laboratory in Southern California, the mission began mapping the sky in May and completed its first all-sky mosaic in December. It will complete three additional all-sky scans during its two-year primary mission, and merging those maps together will increase the sensitivity of the measurements. The entire dataset is freely available to scientists and the public.
“SPHEREx is a mid-sized astrophysics mission delivering big science,” said JPL Director Dave Gallagher. “It’s a phenomenal example of how we turn bold ideas into reality, and in doing so, unlock enormous potential for discovery.”
NASA’s SPHEREx has mapped the entire sky in 102 infrared colors, which are invisible to the human eye but can be used to reveal different features of the cosmos. This image features a selection of colors emitted primarily by stars (blue, green, and white), hot hydrogen gas (blue), and cosmic dust (red).
NASA/JPL-Caltech
This SPHEREx image shows a selection of the infrared colors primarily emitted by stars and galaxies. The space telescope is observing hundreds of millions of distant galaxies across the sky. Its multiwavelength view will help astronomers measure the distance to those galaxies.
NASA/JPL-Caltech
The infrared colors emitted primarily by dust (red) and hot gas (blue), key ingredients for forming new stars and planets, are seen in this SPHEREx image. Though these clouds of material cover a massive portion of the sky, they are invisible in most wavelengths of light, including those the human eye can detect.
NASA/JPL-Caltech
Superpowered telescope
Each of the 102 colors detected by SPHEREx represents a wavelength of infrared light, and each wavelength provides unique information about the galaxies, stars, planet-forming regions, and other cosmic features therein. For example, dense clouds of dust in our galaxy where stars and planets form radiate brightly in certain wavelengths but emit no light (and are therefore totally invisible) in others. The process of separating the light from a source into its component wavelengths is called spectroscopy.
And while a handful of previous missions has also mapped the entire sky, such as NASA’s Wide-field Infrared Survey Explorer, none have done so in nearly as many colors as SPHEREx. By contrast, NASA’s James Webb Space Telescope can do spectroscopy with significantly more wavelengths of light than SPHEREx, but with a field of view thousands of times smaller. The combination of colors and such a wide field of view is why SPHEREx is so powerful.
“The superpower of SPHEREx is that it captures the whole sky in 102 colors about every six months. That’s an amazing amount of information to gather in a short amount of time,” said Beth Fabinsky, the SPHEREx project manager at JPL. “I think this makes us the mantis shrimp of telescopes, because we have an amazing multicolor visual detection system and we can also see a very wide swath of our surroundings.”
To accomplish this feat, SPHEREx uses six detectors, each paired with a specially designed filter that contains a gradient of 17 colors. That means every image taken with those six detectors contains 102 colors (six times 17). It also means that every all-sky map that SPHEREx produces is really 102 maps, each in a different color.
The observatory will use those colors to measure the distance to hundreds of millions of galaxies. Though the positions of most of those galaxies have already been mapped in two dimensions by other observatories, SPHEREx’s map will be in 3D, enabling scientists to measure subtle variations in the way galaxies are clustered and distributed across the universe.

Taken by NASA’s SPHEREx observatory, the maps illustrate how viewing the universe in different wavelengths of light can reveal unique cosmic features. Credit: NASA/JPL-Caltech
Those measurements will offer insights into an event that took place in the first billionth of a trillionth of a trillionth of a second after the big bang. In this moment, called inflation, the universe expanded by a trillion-trillionfold. Nothing like it has occurred in the universe since, and scientists want to understand it better. The SPHEREx mission’s approach is one way to help in that effort.
More about SPHEREx
The SPHEREx mission is managed by JPL for NASA’s Astrophysics Division within the Science Mission Directorate in Washington. The telescope and the spacecraft bus were built by BAE Systems. The science analysis of the SPHEREx data is being conducted by a team of scientists at 10 institutions across the U.S., and in South Korea and Taiwan. Data is processed and archived at IPAC at Caltech in Pasadena, which manages JPL for NASA. The mission’s principal investigator is based at Caltech with a joint JPL appointment. The SPHEREx dataset is publicly available.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
In 2025, NASA’s Stennis Space Center near Bay St. Louis, Mississippi, marked a year of progress by supporting NASA’s Artemis campaign, celebrating historic milestones, and continuing its role as a trusted propulsion test partner at America’s largest rocket propulsion test site.
“For more than six decades, NASA Stennis has proudly represented the Gulf Coast region and America in advancing our nation’s space exploration goals,” said NASA Stennis Director John Bailey. “This year, we continued our progress forward as we near the launch of Artemis II, while honoring milestones that have brought our center to this point.”
Supporting Artemis
As NASA prepares for the launch of Artemis II in early 2026, with the first crewed mission to the Moon in over 50 years, NASA Stennis continues its frontline work.
Every RS-25 engine used to help launch NASA’s SLS (Space Launch System) rocket to the Moon is tested in south Mississippi.
NASA Stennis teams provided data to lead engines contractor L3Harris Technologies by successfully testing two new production RS-25 flight engines.
NASA tested RS-25 engine No. 20001 at the Fred Haise Test Stand in June, and RS-25 engine No. 20002 in November. Each engine fired for 500 seconds, reaching 111% of its rated power, while simulating launch conditions.

Supporting Commercial Propulsion
The commercial aerospace industry is growing, and NASA Stennis is a secure location providing support for it. Companies that have conducted work at NASA Stennis include Blue Origin, Boeing, Evolution Space; Launcher, a Vast company; Relativity Space and Rolls-Royce.
Three companies – Relativity Space, Rocket Lab, and Evolution Space – have established, or continue progress to establish, production and/or test operations at NASA Stennis.
Infrastructure upgrades and planning efforts across the test complex are laying the foundation for future propulsion test projects as well.
“As the commercial space industry continues to accelerate their development, NASA Stennis is adapting to meet their propulsion testing needs,” said Joe Schuyler, director of the NASA Stennis Engineering and Test Directorate. “We are proud that our proven experience makes us a trusted partner.”
Honoring the Past
In 2025, NASA Stennis honored a defining era of space shuttle main engine testing. An image shows the first space shuttle main engine installed on May 8, 1975, at the Fred Haise Test Stand (formerly A-1).
NASA
While NASA Stennis operates as the nation’s largest rocket propulsion test site, the NASA Stennis Federal City also is home to more than 50 federal, state, academic, and commercial tenants.
This year marked the birth of the federal city concept 55 years ago. The unique operating approach serves as a model of government efficiency and a powerful economic engine for the Gulf Coast region.
Meanwhile, the 50thanniversary of space shuttle main engine testing honored a defining era for NASA Stennis.
From May 1975 to July 2009, NASA Stennis tested space shuttle main engines that enabled 135 shuttle missions and notable space milestones, like deployment of the Hubble Space Telescope and construction of the International Space Station.
Both the federal city model and the decades of propulsion excellence continue to inform work at NASA Stennis.
Engineering the Future
Innovation extended beyond the test stands. The versatile testing environment at NASA Stennis is uniquely positioned to support unmanned systems testing across air, land, and water. With restricted airspace, a closed canal system, and vast protected terrain, the site offers a safe, flexible environment for range operations.
In addition to physical infrastructure, NASA Stennis progressed in digital innovation with the release of its first open-source software tool to streamline propulsion test data collection and collaboration across NASA and industry. The peer review tool is designed to facilitate more efficient and collaborative creation of systems applications, such as those used in frontline government and propulsion test work.

Community and Inspiration
NASA Stennis connected with communities in creative ways in 2025.
During Super Bowl week, NASA Stennis representatives inspired future explorers by bringing Artemis mission displays and hands-on activities to families at the Audubon Aquarium in New Orleans.
In March, NASA Stennis supported the third annual FIRST Robotics Magnolia Regional as a lead sponsor with employees and interns volunteering at the event. The competition in Laurel, Mississippi, brought together 37 teams from eight U.S. states (Alabama, California, Florida, Louisiana, Minnesota, Mississippi, Missouri, and Tennessee) and Mexico. The FIRST (For the Inspiration and Recognition of Science and Technology) Robotics event joined NASA’s Robotics Alliance Project to combine the excitement of sport with the rigors of science, technology, engineering, and mathematics (STEM) in field games using industrial-sized robots.
That same spirit of hands-on learning continues at INFINITY Science Center, the official visitor center of NASA Stennis. A new interactive exhibit has provided visitors a chance to become a test conductor and simulate RS-25 engine tests for the engines that will help power NASA’s Artemis missions.
A pair of young visitors to INFINITY Science Center carry out the steps of a simulated RS-25 engine hot fire on Dec. 19, 2024. The engine test simulator exhibit provided by NASA’s Stennis Space Center takes users through the hot fire process just as real engineers do at NASA Stennis.

From Supercomputers to Wind Tunnels: NASA’s Road to Artemis II
This video shows two simulations of the SLS (Space Launch System) rocket using NASA’s Launch Ascent and Vehicle Aerodynamics solver. For the Artemis II test flight, a pair of six-foot-long strakes will be added to the core stage of SLS that will smooth vibrations induced by airflow during ascent. The top simulation is without strakes while the bottom shows the airflow with strakes. The green and yellow colors on the rocket’s surface show how the airflow scrapes against the rocket’s skin. The white and gray areas show changes in air density between the boosters and core stage, with the brightest regions marking shock waves. The strakes reduce vibrations and improves the safety of the integrated vehicle.
NASA/NAS/Gerrit-Daniel Stich, Michael Barad, Timothy Sandstrom, Derek Dalle
By combining the technologies of the NASA Advanced Supercomputing facility and Unitary Plan Wind Tunnel at NASA Ames, researchers were able to simulate and model an adjustment to the Space Launch System (SLS) rocket that could improve airflow and stability to the vehicle during the launch of Artemis II. The collaborative effort between researchers is the next step on NASA’s journey to send astronauts to explore the Moon for scientific discovery, economic benefits, and build the foundation for the first crewed missions to Mars.
New Discoveries in Early Solar System Samples
A microscopic particle of asteroid Bennu, brought to Earth by NASA’s OSIRIS-REx mission, is manipulated under a transmission electron microscope. In order to move the fragment for further analysis, researchers first reinforced it with thin strips of platinum (the “L” shape on the particle’s surface) then welded a tungsten microneedle to it. The asteroid fragment measures 30 micrometers (about one-one thousandth of an inch) across.
NASA
Researchers at NASA Ames discovered a never-before-seen “gum-like” material in pristine asteroid samples delivered to Earth by NASA’s OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer) spacecraft. The surprising substance was likely formed in the early days of the solar system, as Bennu’s young parent asteroid warmed. Such complex molecules could have provided some of the chemical precursors that helped trigger life on Earth, and finding them in the pristine samples from Bennu is important for scientists studying how life began and whether it exists beyond our planet.

Curiosity Mars Rover Uncovers Subsurface Clues to the Planet’s Evolution
NASA’s Curiosity Mars rover sees its tracks receding into the distance at a site nicknamed “Ubajara” on April 30, 2023. This site is where Curiosity made the discovery of siderite, a mineral that may help explain the fate of the planet’s thicker ancient atmosphere.
NASA/JPL-Caltech/MSSS
NASA’s Curiosity Mars rover helped shed new light on what happened to the planet’s ancient atmosphere. Researchers have long believed that Mars once had a thick, carbon dioxide-rich atmosphere and liquid water on the planet’s surface. That carbon dioxide and water should have reacted with Martian rocks to create carbonate minerals, but previous investigations haven’t found expected amounts of carbonate on the planet’s surface. Curiosity used onboard instruments to study powdered Martian rock samples from the subsurface of the planet, finding the presence of siderite, an iron carbonate mineral, within the sulfate-rich rocky layers of Mount Sharp in Mars’ Gale Crater.
Managing Satellite Traffic in Orbit

Managed at NASA Ames, the Starling mission, in collaboration with SpaceX’s Starlink constellation, successfully demonstrated autonomous coordination between spacecraft to improve space traffic management in low Earth orbit. The extended mission, called Starling 1.5, tested how satellite swarms can share maneuver responsibilities and respond more quickly to avoid collisions without relying on time-consuming ground-based communication. This approach aims to streamline space traffic coordination as orbital congestion increases, enabling faster, safer, and more efficient satellite operations.

Steve Howell, a senior research scientist at Ames, used both the ground-based Gemini North telescope in Hawai’i and a special, high-resolution camera built by NASA to directly observe the close companion to Betelgeuse. This discovery may explain why other similar red supergiant stars undergo periodic changes in their brightness on the scale of many years.

New studies aboard the International Space Station are advancing the detection of antibiotic-resistant bacteria, thus improving the health safety not only of astronauts but patients back on Earth. Future astronauts visiting the Moon or Mars will need to rely on a pre-determined supply of antibiotics in case of illness, and ensuring those antibiotics remain effective is an important safety measure for future missions. Infections caused by antibiotic-resistant bacteria can be difficult or impossible to treat, making antibiotic resistance a leading cause of death worldwide and a global health concern.

NASA’s DiskSat technology demonstration mission will test the performance of a new small spacecraft platform designed to expand the capabilities of current small spacecraft. By demonstrating the advantages of a flat, disk-shaped architecture over the conventional CubeSat design, DiskSat aims to enable lower-cost space missions, broaden scientific opportunities, and increase overall access to space.
At 12:03 a.m. EST on Thursday, Dec. 18, DiskSat launched aboard a Rocket Lab Electron rocket from the company’s Launch Complex 2 on Wallops Island, Virginia.
The demonstration will evaluate the performance of the DiskSat spacecraft themselves and a specialized dispenser mechanism. The dispenser is engineered to securely contain four DiskSat spacecraft during launch, then sequentially deploy them into low Earth orbit where they will perform maneuvers. Each DiskSat is a circular, flat spacecraft 40 inches (one meter) in diameter and one inch (two-and-a-half centimeters) thick – similar to a small coffee table. Each has an electric propulsion system to allow for orbit changes and maintenance. The DiskSat design is also conducive to operations in very low Earth orbit, which can offer sharper Earth imaging and sensing capabilities as well as lower latency communications solutions.
DiskSat boosts U.S. innovation and commercial space opportunities while providing mission designers new flexibility, enabling them to pursue and achieve NASA’s goals faster and more affordably. DiskSats offer an alternative platform that could significantly expand the scope of future small spacecraft missions for NASA, the commercial space industry, other government agencies, and academia. The DiskSat demonstration also supports NASA’s long-term plans for sustained exploration at the Moon and Mars as well as advancing our ability to study and better understand our home planet.

NASA eClips STEM Student Ambassadors Shine at STEM Exploration Community Event
STEM Student Ambassadors engage the community in learning about auroras.
The 5th Annual Science, Technology, Engineering, & Mathematics (STEM) Exploration Community Event hosted by the Coastal Virginia STEM Hub and the NASA eClips Education Team from the National Institute of Aerospace Center for Integrative STEM Education (NIA-CISE) lit up the Professional Workforce Development Center at Virginia Peninsula Community College on Saturday, November 8, 2025. The hard work of 12 NASA eClips STEM Student Ambassadors brought extraordinary energy, expertise, and heart to the more than 1,000 attendees on National STEM Day.
The STEM Student Ambassador Program was initiated to help grow the STEM ecosystem in coastal Virginia by extending the reach of the NASA eClips Education Team. The Ambassadors are high school students selected through a highly competitive regional recruiting process who undergo a rigorous training with the NASA eClips Education Team and NASA Science Communication interns.
“NASA eClips STEM Student Ambassadors enjoyed inspiring community members by sharing their knowledge about the Sun.”
Betsy McAllister
Educator in Residence National Institute of Aerospace – Center for Integrative STEM Education
At the STEM Exploration Community Event, the NASA eClips exhibit quickly became a hub of excitement as the Ambassadors used art as a launchpad to explore heliophysics concepts, guiding visitors from preK-adult in creating chalk coronas and pastel auroras. The enthusiasm was contagious: children leaned in, families asked questions, and even adults rediscovered a sense of wonder as the Ambassadors connected hands-on creativity to the science of the Sun. The Ambassadors shared their personal STEM journeys, encouraged younger learners to pursue curiosity, and modeled what it looks like to be confident, informed science communicators.
The Ambassadors worked behind the scenes to support event logistics, networked with STEM leaders, and even represented the high-school perspective on a STEM panel. Ambassador Layla Criner offered practical advice on how students can get involved, and stay involved, in STEM. The powerful impact of the Ambassadors underscored why this NASA eClips program matters: it empowers students not only to communicate NASA science, but to lead it.
NASA eClips, led by the NIA-CISE, is supported by NASA under cooperative agreement award number NNX16AB91A and is part of NASA’s Science Activation Portfolio. The mission of NASA eClips is to engage and inspire students in STEM through the lens of NASA by delivering standards-aligned, web-based resources that support learning both in and out of the classroom.

NASA’s Fermi Spots Young Star Cluster Blowing Gamma-Ray Bubbles
For the first time, astronomers using NASA’s Fermi Gamma-ray Space Telescope have traced a budding outflow of gas from a cluster of young stars in our galaxy — insights that help us understand how the universe has evolved as NASA explores the secrets of the cosmos for the benefit of all.
The cluster, called Westerlund 1, is located about 12,000 light-years away in the southern constellation Ara. It’s the closest, most massive, and most luminous super star cluster in the Milky Way. The only reason Westerlund 1 isn’t visible to the unaided eye is because it’s surrounded by thick clouds of dust. Its outflow extends below the plane of the galaxy and is filled with high-speed, hard-to-study particles called cosmic rays.
“Understanding cosmic ray outflows is crucial to better comprehending the long-term evolution of the Milky Way,” said Marianne Lemoine-Goumard, an astrophysicist at the University of Bordeaux in France. “We think these particles carry a large amount of the energy released within clusters. They could help drive galactic winds, regulate star formation, and distribute chemical elements within the galaxy.”
A paper detailing the results published Dec. 9 in Nature Communications. Lemoine-Goumard led the research with Lucia Härer and Lars Mohrmann, both at the Max Planck Institute for Nuclear Physics in Heidelberg, Germany.
This image of super star cluster Westerlund 1 was captured with the Near-InfraRed Camera on NASA’s James Webb’s Space Telescope. The cluster is largely hidden at visible wavelengths by dust clouds, which infrared light penetrates. Westerlund 1’s large, dense, and diverse stellar population of massive stars has no other known counterpart in the Milky Way.

Super star clusters like Westerlund 1 contain more than 10,000 times our Sun’s mass. They are also more luminous and contain higher numbers of rare, massive stars than other clusters.
Scientists think that supernova explosions and stellar winds within star clusters push ambient gas outward, propelling cosmic rays to near light speed. About 90% of these particles are hydrogen nuclei, or protons, and the remainder are electrons and the nuclei of heavier elements.
Because cosmic ray particles are electrically charged, they change course when they encounter magnetic fields. This means scientists can’t trace them back to their sources. Gamma rays, however, travel in a straight line. Gamma rays are the highest-energy form of light, and cosmic rays produce gamma rays when they interact with matter in their environment.
Most gamma-ray observations of stellar clusters have limited resolution, so astronomers effectively see them as indistinct areas of emission. Because Westerlund 1 is so close and bright, however, it’s easier to study.
Westerlund 1 is located closer to the center of the Milky Way than our Sun, as shown in this artist’s concept. Westerlund 1 is one of only a few known super star clusters in our galaxy and is the closest, brightest, and most massive one discovered so far.
NASA’s Goddard Space Flight Center/Conceptual Image Lab
This artist’s concept shows the location of Westerlund 1 relative to our Sun as seen from the underside of our Milky Way galaxy. The magenta bubble illustrates what the nascent outflow might look like in gamma rays. Westerlund 1 is located slightly below the middle of the galactic disk, so stellar activity pushes gas preferentially along a path of lower density beneath the disk.
NASA’s Goddard Space Flight Center/Conceptual Image Lab
In 2022, scientists using a group of telescopes in Namibia operated by the Max Planck Institute called the High Energy Spectroscopic System detected a distinct ring of gamma rays around Westerlund 1 with energies trillions of times higher than visible light.
Lemoine-Goumard, Härer, and Mohrmann wondered if the cluster’s unique properties might allow them to see other details by looking back through nearly two decades of Fermi data at slightly lower energies — millions to billions of times the energy of visible light.
Fermi’s sensitivity and resolution allowed the researchers to filter out other gamma-ray sources like rapidly spinning stellar remnants called pulsars, background radiation, and Westerlund 1 itself.
What was left was a bubble of gamma rays extending over 650 light-years from the cluster below the plane of the Milky Way. That means the outflow is about 200 times larger than Westerlund 1 itself.
Data from NASA’s Fermi Gamma-ray Space Telescope reveal the budding gas bubble of star cluster Westerlund 1. Brighter colors indicate a stronger likelihood that gamma rays arise from specific types of point sources, notably two pulsars located at center and in the brightest portion of the image. Pink contours denote steep changes in likelihood. An underlying orange-magenta feature extends down the image, starting from the cluster’s location, and represents the nascent outflow. The grey lines indicate distance below the galactic plane. The bubble is over 650 light-years long and angles slightly away from us. Westerlund 1’s stellar activity more easily pushes gas outward into lower-density regions of the galaxy’s disk.
NASA’s Goddard Space Flight Center/Lemoine-Goumard et al. 2025; ESA/Webb, NASA & CSA, M. Zamani (ESA/Webb), M. G. Guarcello (INAF-OAPA) and the EWOCS team
The researchers call this a nascent, or early stage, outflow because it was likely recently produced by massive young stars within the cluster and hasn’t yet had time to break out of the galactic disk. Eventually it will stream into the galactic halo, the hot gas surrounding the Milky Way.
Westerlund 1 is located slightly below the galactic plane, so the researchers think the gas expanded asymmetrically, following the path of least resistance into a zone of lower density below the disk.
“One of the next steps is to model how the cosmic rays travel across this distance and how they create a changing gamma-ray energy spectrum,” Härer said. “We’d also like to look for similar features in other star clusters. We got very lucky with Westerlund 1, though, since it’s so massive, bright, and close. But now we know what to look for, and we might find something even more surprising.”
“Since it started operations 17 years ago, Fermi has continued to advance our understanding of the universe around us,” said Elizabeth Hays, Fermi’s project scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “From activity in distant galaxies to lightning storms in our own atmosphere, the gamma-ray sky continues to astound us.”
STS110-E-5541 (13 April 2002) — Astronaut Lee M.E. Morin carries an affixed 35mm camera to record work which is being performed 240 miles above Earth on the International Space Station (ISS).
NASA astronaut and retired United States Navy Capt. Lee Morin has retired from the agency after 30 years of service. He served as a mission specialist on STS-110 and went on to oversee the Rapid Prototyping Laboratory and technology development for the International Space Station and NASA’s Commercial Crew Program, as well as its Artemis campaign.
“Lee’s contributions throughout his career are immense and immeasurable,” said Vanessa Wyche, director of NASA’s Johnson Space Center in Houston. “His expertise and enthusiasm followed him whether he was working with the agency’s most seasoned engineers, or an intern just starting out. We’ll feel the impact of his innovations for decades to come, and I cannot thank him enough for his service.”
The New Hampshire native and physician flew aboard space shuttle Atlantis in support of STS-110 in 2002. The mission delivered the cornerstone truss to the space station. It also marked the first time the station’s robotic arm was used to assist spacewalkers, and the first spacewalks conducted from the station’s Quest airlock. During the mission, Morin performed two spacewalks, spending a total of 14 hours and 9 minutes working outside the station. He accumulated 10 days and 19 hours in space.
“Lee’s footprint on human spaceflight can be felt by every astronaut in our corps,” said Chief Astronaut Scott Tingle. “He set the new standard for the way spacecraft cockpits are designed and built, resulting in more efficient astronaut training and safer spaceflight overall. I have long admired his drive to always try something new. I’m proud to call him my lifelong friend and wish him nothing but the best.”
After his spaceflight, Morin used his experience to improve how astronauts interact with spacecraft systems. He helped design the software displays used during missions aboard the space station and Orion spacecraft. As lead astronaut on a team that created a standardized graphical interface for space station crews, Morin ensured early missions had clear, consistent displays and procedures. His work bridged the gap between engineering and usability, earning recognition from the U.S. Patent and Trademark Office for innovations that continue to make spaceflight safer and more efficient.
“Working with the brilliant teams here at NASA has been the honor of a lifetime,” Morin said. “Throughout my career I’ve had the honor of seeing some of the greatest achievements in human spaceflight, and I couldn’t have done it without the support of the countless mentors, collaborators, and friends I’ve met along the way. While I’m departing the agency, I will remain an avid follower to see where human spaceflight goes next, and I am humbled and proud to say that I got to be a part of where it all began.”
Morin was selected as an astronaut in 1996. He holds multiple degrees, including master’s degrees in biochemistry, public health, and physics. He earned his medical degree from New York University. Before he came to NASA, he served as a Naval flight surgeon, diving medical officer, and held key roles in aerospace medicine.

This image from NASA’s Mars Perseverance rover shows a potential megablock on the Jezero crater rim, taken by the Mastcam-Z instrument’s “right eye.” Mastcam-Z is a pair of cameras located high on the rover’s mast. Perseverance acquired this image looking east across the rim heading towards “Lac de Charmes” on Dec. 7, 2025 — Sol 1706, or Martian day 1,706 of the Mars 2020 mission — at the local mean solar time of 13:38:46.
NASA/JPL-Caltech/ASU
Written by Margaret Deahn, Ph.D. student at Purdue University
NASA’s Mars 2020 rover is currently trekking towards exciting new terrain. After roughly four months of climbing up and over the rim of Jezero crater, the rover is taking a charming tour of the plains just beyond the western crater rim, fittingly named “Lac de Charmes.” This area just beyond Jezero’s rim will be the prime place to search for pre-Jezero ancient bedrock and Jezero impactites — rocks produced or affected by the impact event that created Jezero crater.
The formation of a complex crater like Jezero is, well… complex. Scientists who study impact craters like to split the formation process into three stages: contact & compression (when the impactor hits), excavation (when materials are thrown out of the crater), and modification (when gravity causes everything to collapse). This process happens incredibly fast, fracturing the impacted rock and even melting some of the target material. Sometimes on Earth, the classic “bowl” shaped crater has been completely weathered and unrecognizable, so geologists are able to identify craters by the remnants of their impactites. Just when you thought it couldn’t get any more complicated — Jezero crater’s rim is located on the rim of another, even bigger basin called Isidis. That means there is an opportunity to have impactites from both cratering events exposed in and just around the rim — some of which could be several billions of years old! We may have already encountered one of these blocks on our trek towards Lac de Charmes. In the foreground of this image taken by the Mastcam-Z instrument on the rover, there is a potential impactite called a “megablock” that the team has named “Hyha.” We can actually see this block from orbit, it is that large! The team is excited to continue exploring these ancient rocks as we take our next steps off Jezero’s rim.
