NASA Reveals New Details About Dark Matter’s Influence on Universe
With the Webb telescope’s unprecedented sensitivity, scientists are learning more about dark matter’s influence on stars, galaxies, and even planets like Earth.
Scientists using data from NASA’s James Webb Space Telescope have made one of the most detailed, high-resolution maps of dark matter ever produced. It shows how the invisible, ghostly material overlaps and intertwines with “regular” matter, the stuff that makes up stars, galaxies, and everything we can see.
Published Monday, Jan. 26, in Nature Astronomy, the map builds on previous research to provide additional confirmation and new details about how dark matter has shaped the universe on the largest scales — galaxy clusters millions of light-years across — that ultimately give rise to galaxies, stars, and planets like Earth.
“This is the largest dark matter map we’ve made with Webb, and it’s twice as sharp as any dark matter map made by other observatories,” said Diana Scognamiglio, lead author of the paper and an astrophysicist at NASA’s Jet Propulsion Laboratory in Southern California. “Previously, we were looking at a blurry picture of dark matter. Now we’re seeing the invisible scaffolding of the universe in stunning detail, thanks to Webb’s incredible resolution.”
Created using data from NASA’s Webb telescope in 2026 (right) and from the Hubble Space Telescope in 2007 (left), these images show the presence of dark matter in the same region of sky. Webb’s higher resolution is providing new insights into how this invisible component influences the distribution of ordinary matter in the universe.NASA/STScI/A. Pagan Dense regions of dark matter are connected by lower-density filaments, forming a weblike structure known as the cosmic web. This pattern appears more clearly in the Webb data than in the earlier Hubble image. Ordinary matter, including galaxies, tends to trace this same underlying structure shaped by dark matter.NASA/STScI/A. Pagan Some dark matter structures appear smaller in the Webb data because they are coming into sharper focus. Webb’s higher resolution also makes it possible to better confine the size and location of the dark matter clusters in the lower left of the image.NASA/STScI/A. PaganDark matter doesn’t emit, reflect, absorb, or even block light, and it passes through regular matter like a ghost. But it does interact with the universe through gravity, something the map shows with a new level of clarity. Evidence for this interaction lies in the degree of overlap between dark matter and regular matter. According to the paper’s authors, Webb’s observations confirm that this close alignment can’t be a coincidence but, rather, is due to dark matter’s gravity pulling regular matter toward it throughout cosmic history.
“Wherever we see a big cluster of thousands of galaxies, we also see an equally massive amount of dark matter in the same place. And when we see a thin string of regular matter connecting two of those clusters, we see a string of dark matter as well,” said Richard Massey, an astrophysicist at Durham University in the United Kingdom and a coauthor of the new study. “It’s not just that they have the same shapes. This map shows us that dark matter and regular matter have always been in the same place. They grew up together.”
Closer lookFound in the constellation Sextans, the area covered by the new map is a section of sky about 2.5 times larger than the full Moon. A global community of scientists have observed this region with at least 15 ground- and space-based telescopes for the Cosmic Evolution Survey (COSMOS). Their goal: to precisely measure the location of regular matter here and then compare it to the location of dark matter. The first dark matter map of the area was made in 2007 using data from NASA’s Hubble Space Telescope, a project led by Massey and JPL astrophysicist Jason Rhodes, a coauthor of the paper.
Webb peered at this region for a total of about 255 hours and identified nearly 800,000 galaxies, some of which were detected for the first time. Scognamiglio and her colleagues then looked for dark matter by observing how its mass curves space itself, which in turn bends the light traveling to Earth from distant galaxies. When observed by researchers, it’s as if the light of those galaxies has passed through a warped windowpane.
The Webb map contains about 10 times more galaxies than maps of the area made by ground-based observatories and twice as many as Hubble’s. It reveals new clumps of dark matter and captures a higher-resolution view of the areas previously seen by Hubble.
To refine measurements of the distance to many galaxies for the map, the team used Webb’s Mid-Infrared Instrument (MIRI), designed and managed through launch by JPL, along with other space- and ground-based telescopes. The wavelengths that MIRI detects also make it adept at detecting galaxies obscured by cosmic dust clouds.
Why it mattersWhen the universe began, regular matter and dark matter were probably sparsely distributed. Scientists think dark matter began to clump together first and that those dark matter clumps then pulled together regular matter, creating regions with enough material for stars and galaxies to begin to form.
In this way, dark matter determined the large-scale distribution of galaxies in the universe. And by prompting galaxy and star formation to begin earlier than they would have otherwise, dark matter’s influence also played a role in creating the conditions for planets to eventually form. That’s because the first generations of stars were responsible for turning hydrogen and helium — which made up the vast majority of atoms in the early universe — into the rich array of elements that now compose planets like Earth. In other words, dark matter provided more time for complex planets to form.
“This map provides stronger evidence that without dark matter, we might not have the elements in our galaxy that allowed life to appear,” said Rhodes. “Dark matter is not something we encounter in our everyday life on Earth, or even in our solar system, but it has definitely influenced us.”
Scognamiglio and some of her coauthors will also map dark matter with NASA’s upcoming Nancy Grace Roman Space Telescope over an area 4,400 times bigger than the COSMOS region. Roman’s primary science goals include learning more about dark matter’s fundamental properties and how they may or may not have changed over cosmic history. But Roman’s maps won’t beat Webb’s spatial resolution. More detailed looks at dark matter will be possible only with a next-generation telescope like the Habitable Worlds Observatory, NASA’s next astrophysics flagship concept.
More about WebbThe James Webb Space Telescope is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and CSA (Canadian Space Agency).

NASA Selects Participants to Track Artemis II Mission
NASA has selected 34 global volunteers to track the Orion spacecraft during the crewed Artemis II mission’s journey around the Moon.
The Artemis II test flight will launch NASA’s Space Launch System (SLS) rocket, carrying the Orion spacecraft and a crew of four astronauts, on a mission into deep space. The agency’s second mission in the Artemis campaign is a key step in NASA’s path toward establishing a long-term presence at the Moon and confirming the systems needed to support future lunar surface exploration and paving the way for the first crewed mission to Mars.
While NASA’s Near Space Network and Deep Space Network, coordinated by the agency’s SCaN (Space Communication and Navigation) program , will provide primary communications and tracking services to support Orion’s launch, journey around the Moon, and return to Earth, participants selected from a request for proposals published in August 2025, comprised of established commercial service providers, members of academia, and individual amateur radio enthusiasts will use their respective equipment to passively track radio waves transmitted by Orion during its approximately 10-day journey.
The Orion capsule viewing the Moon during Artemis I. NASA“The Artemis II tracking opportunity is a real step toward SCaN’s commercial-first vision. By inviting external organizations to demonstrate their capabilities during a human spaceflight mission, we’re strengthening the marketplace we’ll rely on as we explore farther into the solar system,” said Kevin Coggins, deputy associate administrator for SCaN at NASA Headquarters in Washington. “This isn’t about tracking one mission, but about building a resilient, public-private ecosystem that will support the Golden Age of innovation and exploration.”

These volunteers will submit their data to NASA for analysis, helping the agency better assess the broader aerospace community’s tracking capabilities and identify ways to augment future Moon and Mars mission support. There are no funds exchanged as a part of this collaborative effort.
This initiative builds on a previous effort in which 10 volunteers successfully tracked the Orion spacecraft during Artemis I in 2022. That campaign produced valuable data and lessons learned, including implementation, formatting, and data quality variations for Consultative Committee for Space Data Systems, which develops communications and data standards for spaceflight. To address these findings, SCaN now requires that all tracking data submitted for Artemis II comply with its data system standards.
Compared to the previous opportunity, public interest in tracking the Artemis II mission has increased. About 47 ground assets spanning 14 different countries will be used for to track the spacecraft during its journey around the Moon.

Your browser does not support the audio element.During NASA’s Artemis II mission around the Moon, the astronauts inside the Orion spacecraft will be wearing specialized pressure suits designed to protect them throughout their journey. At NASA’s Johnson Space Center in Houston, Dustin Gohmert leads the team responsible for these suits, known as the Orion Crew Survival System (OCSS).
“We work with the crew to say, ‘Here’s this design concept we have. How does this really work in the spaceflight environment?’” Gohmert said. “As we evolve the design, we take the crew’s input and we adapt the suit over time to take into account not only the desire we have for safety, but the real-world impacts that it has.”
The suits will protect astronauts on launch day, throughout high-risk parts of missions near the Moon, during the high-speed return to Earth, and in emergency situations if such events arise. The OCSS suits are engineered to sustain life for up to six days in the event of an emergency, and can provide the astronauts oxygen, hydration, food, and waste management needed on their way back to Earth.

Gohmert’s team in the Orion Crew Survival Systems Lab manages every phase of the suits, including processing, designing, qualifying, and testing them for the mission, as well as integrating them with the Orion spacecraft. Their work addresses engineering challenges, such as how much internal pressure the suit can safely maintain and for how long.
The team custom-builds each suit to fit the anatomy of the astronauts. Crew members undergo detailed sizing and multiple fit checks to ensure precision, and their feedback is a key part of the design evolution and refinement of the suit.

He worked through the end of the Space Shuttle Program and later transitioned to Orion. Working on the suit throughout his career has been both technically challenging and a deeply personal responsibility.

The International Space Station was orbiting 262 miles above the Mediterranean Sea at approximately 10:02 p.m. local time when the image was captured.
Also known as the northern lights (aurora borealis) or southern lights (aurora australis), auroras are colorful, dynamic, and often visually delicate displays of an intricate dance of particles and magnetism between the Sun and Earth called space weather. When energetic particles from space collide with atoms and molecules in the atmosphere, they can cause the colorful glow that we call auroras.

NASA Finds Lunar Regolith Limits Meteorites as Source of Earth’s Water

NASA Finds Lunar Regolith Limits Meteorites as Source of Earth’s Water A close-up view of a portion of a “relatively fresh” crater, looking southeast, as photographed during the third Apollo 15 lunar surface moonwalk. Credit: NASAA new NASA study of its Apollo lunar soils clarifies the Moon’s record of meteorite impacts and timing of water delivery. These findings place upper bounds on how much water meteorites could have supplied later in Earth’s history.
Research has previously shown that meteorites may have been a significant source of Earth’s water as they bombarded our planet early in the solar system’s development. In a paper published Tuesday in the Proceedings to the National Academy of Sciences, researchers led by Tony Gargano, a postdoctoral fellow at NASA’s Johnson Space Center and the Lunar and Planetary Institute (LPI), both in Houston, used a novel method for analyzing the dusty debris that covers the Moon’s surface called regolith. They learned that even under generous assumptions, meteorite delivery since about four billion years ago could only have supplied a small fraction of Earth’s water.
The Moon serves as an ancient archive of the impact history the Earth-Moon system has experienced over billions of years. Where Earth’s dynamic crust and weather erase such records, lunar samples preserve them. The records don’t come without challenge, though. Traditional methods of studying regolith have relied on analyzing metal-loving elements. These elements can get muddied by repeated impacts on the Moon, making it harder to untangle and reconstruct what the original meteoroids contained.
Enter triple oxygen isotopes, high precision “fingerprints” that take advantage of the fact that oxygen, the dominant element by mass in rocks, is unaffected by impact or other external forces. The isotopes offer a clearer understanding of the composition of meteorites that impacted the Earth-Moon system. The oxygen-isotope measurements revealed that at least ~1% by mass of the regolith contained material from carbon-rich meteorites that were partially vaporized when they hit the Moon. Using the known properties of such meteorites allowed the team to calculate the amount of water that would have been carried within.
“The lunar regolith is one of the rare places we can still interpret a time-integrated record of what was hitting Earth’s neighborhood for billions of years,” said Gargano. “The oxygen-isotope fingerprint lets us pull an impactor signal out of a mixture that’s been melted, vaporized, and reworked countless times.”
The findings have implications for our understanding of water sources on Earth and the Moon. When scaled up by roughly 20 times to account for the substantially higher rate of impacts on Earth, the cumulative water shown in the model made up only a small percent of the water in Earth’s oceans. That makes it difficult to reconcile the hypothesis that late delivery of water-rich meteorites was the dominant source of Earth’s water.
“Our results don’t say meteorites delivered no water,” added co-author Justin Simon, a planetary scientist at NASA Johnson’s Astromaterials Research and Exploration Science Division. “They say the Moon’s long-term record makes it very hard for late meteorite delivery to be the dominant source of Earth’s oceans.”
For the Moon, the implied delivery since about 4 billion years ago is tiny on an Earth-ocean scale but is not insignificant for the Moon. The Moon’s accessible water inventory is concentrated in small, permanently shadowed regions at the North and South Poles. These are some of the coldest spots in the solar system and introduce unique opportunities for scientific discovery and potential resources for lunar exploration when NASA lands astronauts on the Moon through Artemis III and beyond.
The samples analyzed for this study came from parts of the Moon near the equator on the side of the Moon facing Earth, where all six Apollo missions landed. The rocks and dust collected more than 50 years ago continue to reveal new insights but are constrained to a small portion of the Moon. Samples delivered through Artemis will open the door for a new generation of discoveries for decades to come.
“I’m part of the next generation of Apollo scientists —people who didn’t fly the missions, but who were trained on the samples and the questions Apollo made possible,” said Gargano. “The value of the Moon is that it gives us ground truth: real, physical material we can measure in the lab and use to anchor what we infer from orbital data and telescopes. I can’t wait to see what the Artemis samples have to teach us and the next generation about our place in the solar system.”

NASA’s Chandra Releases Deep Cut From Catalog of Cosmic Recordings
Like a recording artist who has had a long career, NASA’s Chandra X-ray Observatory has a “back catalog” of cosmic recordings that is impossible to replicate. To access these X-ray tracks, or observations, the ultimate compendium has been developed: the Chandra Source Catalog (CSC).
The CSC contains the X-ray data detected up to the end of 2020 by Chandra, the world’s premier X-ray telescope and one of NASA’s “Great Observatories.” The latest version of the CSC, known as CSC 2.1, contains over 400,000 unique compact and extended sources and over 1.3 million individual detections in X-ray light.

Wolk This image is the sum of 86 observations added together, representing over three million seconds of Chandra observing time. It spans just about 60 light-years across, which is a veritable pinprick on the entire sky.

This allows scientists using other telescopes — both on the ground and in space including NASA’s James Webb and Hubble Space Telescopes — to combine this unique X-ray data with information from other types of light.
The richness of the Chandra Source Catalog is illustrated in a new image of the Galactic Center, the region around the supermassive black hole at the center of the Milky Way galaxy called Sagittarius A*.

Another new representation of the vast scope of the Chanda Source Catalog is found in a just-released sonification, the translation of astronomical data into sound. This sonification encompasses the new map that includes 22 years of Chandra observations across the sky, beginning from its launch through its observations in 2021. Because many X-ray sources have been observed multiple times over the life of the Chandra mission, this sonification represents those repeat X-ray sightings over time through different notes.

Visual DescriptionA very deep Chandra X-ray Observatory image around the Sagittarius A* supermassive black hole, located in the center of the Milky Way galaxy, is shown. The image is dominated by burnt orange, deep gold and blue hues, with a sprinkling of rich green. The area looks both intricate and full, with a dense population of tiny dots, along with larger clumps and diffuse areas and nebulous areas peeking through.
At the center of the image, there is a bright, lumpy area in pale gold showing the intense X-ray radiation emanating from the Sagittarius A* black hole. In the surrounding area, there are more smaller lumps layered throughout, feathering out to a large almost butterfly shape filling much of the screen. The image appears textured, like dozens of blue and orange glow worms are paused in their wriggling.
The image offers an unprecedented view of lobes of hot gas extending for a dozen light years on either side of the black hole. These lobes provide evidence for powerful eruptions occurring several times over the last ten thousand years. The image also contains several mysterious X-ray filaments, some of which may be huge magnetic structures interacting with streams of energetic electrons produced by rapidly spinning neutron stars. Such features are known as pulsar wind nebulas. Chandra has detected over 3,300 individual sources that emit X-rays in this field of view. This image is the sum of 86 observations added together, representing over three million seconds of Chandra observing time.
