Perseus Cluster: X-ray: NASA/CXC/SAO/V. Olivares et al.; Optical/IR: DSS; H-alpha: CFHT/SITELLE; Centaurus Cluster: X-ray: NASA/CXC/SAO/V. Olivaresi et al.; Optical/IR: NASA/ESA/STScI; H-alpha: ESO/VLT/MUSE; Image Processing: NASA/CXC/SAO/N. Wolk Astronomers have taken a crucial step in showing that the most massive black holes in the universe can create their own meals. Data from NASA’s Chandra X-ray Observatory and the Very Large Telescope (VLT) provide new evidence that outbursts from black holes can help cool down gas to feed themselves.
This study was based on observations of seven clusters of galaxies. The centers of galaxy clusters contain the universe’s most massive galaxies, which harbor huge black holes with masses ranging from millions to tens of billions of times that of the Sun. Jets from these black holes are driven by the black holes feasting on gas.
These images show two of the galaxy clusters in the study, the Perseus Cluster and the Centaurus Cluster. Chandra data represented in blue reveals X-rays from filaments of hot gas, and data from the VLT, an optical telescope in Chile, shows cooler filaments in red.
The results support a model where outbursts from the black holes trigger hot gas to cool and form narrow filaments of warm gas. Turbulence in the gas also plays an important role in this triggering process.
According to this model, some of the warm gas in these filaments should then flow into the centers of the galaxies to feed the black holes, causing an outburst. The outburst causes more gas to cool and feed the black holes, leading to further outbursts.
This model predicts there will be a relationship between the brightness of filaments of hot and warm gas in the centers of galaxy clusters. More specifically, in regions where the hot gas is brighter, the warm gas should also be brighter. The team of astronomers has, for the first time, discovered such a relationship, giving critical support for the model.
This result also provides new understanding of these gas-filled filaments, which are important not just for feeding black holes but also for causing new stars to form. This advance was made possible by an innovative technique that isolates the hot filaments in the Chandra X-ray data from other structures, including large cavities in the hot gas created by the black hole’s jets.
The newly found relationship for these filaments shows remarkable similarity to the one found in the tails of jellyfish galaxies, which have had gas stripped away from them as they travel through surrounding gas, forming long tails. This similarity reveals an unexpected cosmic connection between the two objects and implies a similar process is occurring in these objects.
This work was led by Valeria Olivares from the University of Santiago de Chile, and was published Monday in Nature Astronomy. The study brought together international experts in optical and X-ray observations and simulations from the United States, Chile, Australia, Canada, and Italy. The work relied on the capabilities of the MUSE (Multi Unit Spectroscopic Explorer) instrument on the VLT, which generates 3D views of the universe.
NASA’s Marshall Space Flight Center in Huntsville, Alabama, manages the Chandra program. The Smithsonian Astrophysical Observatory’s Chandra X-ray Center controls science operations from Cambridge, Massachusetts, and flight operations from Burlington, Massachusetts.

Visual Description
This release features composite images shown side-by-side of two different galaxy clusters, each with a central black hole surrounded by patches and filaments of gas. The galaxy clusters, known as Perseus and Centaurus, are two of seven galaxy clusters observed as part of an international study led by the University of Santiago de Chile.
In each image, a patch of purple with neon pink veins floats in the blackness of space, surrounded by flecks of light. At the center of each patch is a glowing, bright white dot. The bright white dots are black holes. The purple patches represent hot X-ray gas, and the neon pink veins represent filaments of warm gas. According to the model published in the study, jets from the black holes impact the hot X-ray gas. This gas cools into warm filaments, with some warm gas flowing back into the black hole. The return flow of warm gas causes jets to again cool the hot gas, triggering the cycle once again.
While the images of the two galaxy clusters are broadly similar, there are significant visual differences. In the image of the Perseus Cluster on the left, the surrounding flecks of light are larger and brighter, making the individual galaxies they represent easier to discern. Here, the purple gas has a blue tint, and the hot pink filaments appear solid, as if rendered with quivering strokes of a paintbrush. In the image of the Centaurus Cluster on the right, the purple gas appears softer, with a more diffuse quality. The filaments are rendered in more detail, with feathery edges, and gradation in color ranging from pale pink to neon red.

4 Min Read NASA Space Tech’s Favorite Place to Travel in 2025: The Moon!
The first image from space of Firefly's Blue Ghost mission 1 lunar lander as it begins its 45-day transit period to the Moon. Credits: Firefly Aerospace NASA Space Technology has big travel plans for 2025, starting with a trip to the near side of the Moon!
Among ten groundbreaking NASA science and technology demonstrations, two technologies are on a ride to survey lunar regolith – also known as “Moon dust” – to better understand surface interactions with incoming lander spacecraft and payloads conducting experiments on the surface. These dust demonstrations and the data they’re designed to collect will help support future lunar missions.
Blue Ghost Mission 1 launched at 1:11 a.m. EST aboard a SpaceX Falcon 9 rocket from Launch Complex 39A at the agency’s Kennedy Space Center in Florida. The company is targeting a lunar landing on Sunday, March 2.
The first image from space of Firefly’s Blue Ghost mission 1 lunar lander as it begins its 45-day transit period to the Moon. Firefly Aerospace NASA Space Technology on Blue Ghost Mission 1
NASA’s Electrodynamic Dust Shield (EDS) will lift, transport, and remove particles using electric fields to repel and prevent hazardous lunar dust accumulation on surfaces. The agency’s Stereo Camera for Lunar Plume-Surface Studies (SCALPSS) technology will use stereo imaging to capture the impact of rocket plumes on lunar regolith as the lander descends to the Moon’s surface, returning high-resolution images that will help in creating models to predict regolith erosion – an important task as bigger, heavier payloads are delivered to the Moon in close proximity to each other.
The EDS and SCALPSS technologies will be delivered to the Moon on Firefly’s first Blue Ghost mission, named Ghost Riders in the Sky, as part of NASA’s CLPS (Commercial Lunar Payload Services) initiative. Its landing target is a 300-mile-wide basin located on the Moon’s near side, called Mare Crisium – a large, dark, basaltic plain that filled an ancient asteroid impact. First-of-their-kind experiments will deploy after landing to gather important data in a broad spectrum of areas including geophysical characteristics, global navigation, radiation tolerant computing, and the behavior of lunar regolith.
Replicating the Moon’s harsh environment on Earth is a significant challenge because of extreme temperatures, low gravity, radiation, and dusty surface. The CLPS initiative provides unprecedented access to the lunar surface, allowing us to demonstrate technologies in the exact conditions they were designed for. Missions like Blue Ghost Mission 1 are a true game changer for NASA technology advancement and demonstration.”

The Moon’s dusty environment was one of the greatest challenges astronauts faced during Apollo Moon missions, posing hazards to lunar surface systems, space suits, habitats, and instrumentation. What was learned from those early missions – and from thousands of experiments conducted on Earth and in space since – is that successful surface missions require the ability to eliminate dust from all kinds of systems. Lunar landings, for example, cause lunar dust to disperse in all directions and collect on everything that lands there with it. This is one of the reasons such technologies are important to understand. The SCALPSS technology will study the dispersion of lunar dust, while EDS will demonstrate a solution to mitigate it.
Getting this new data on lunar regolith with be pivotal for our understanding of the lunar surface. We’ve long known that lunar dust is a huge challenge. The Lunar Surface Innovation Initiative has enabled us to initiate lunar dust mitigation efforts across the agency, working with industry and international partners. The lunar science, exploration, and technology communities are eager to have new quantitative data, and to prove laboratory experiments and develop technology solutions.”

[VIDEO] Dust on the lunar surface is a significant hazard for systems and astronauts living and working on the Moon. NASA space technologies are developing solutions to retire hurdles in this capability area. NASA Space Technology Dust mitigation technology has come a long way, but we still have a lot to learn to develop surface systems and infrastructure for more complex missions. LSII is actively engaged in this effort, working with the lunar community across sectors to expand knowledge and design new approaches for future technologies. Working alongside the Lunar Surface Innovation Consortium, LSII has a unique opportunity to take a holistic look at dust’s role in the development of surface infrastructure with other key capability areas including in-situ resource utilization, surface power, and surviving the lunar night.
Learning from the the Moon benefits Mars science and exploration
Capabilities for minimizing dust interaction are as important for future missions on Mars as it is for missions on the Moon. Like the Moon, Mars is also covered with regolith, also called Martian dust or Martian soil, but the properties are different than lunar regolith, both in shape and mineralogy. The challenges Mars rovers have encountered with Martian regolith have provided great insight into the challenges we will face during lunar surface missions. Learning is interwoven and beneficial to future missions whether hundreds of thousands of miles from Earth, on the Moon, or millions, on Mars.

NASA JPL is readying for, clockwise from lower right, the launches of CADRE (its engineering models are seen here), Lunar Trailblazer, NISAR (seen in an artist’s concept), Sentinel-6B (artist’s concept), and SPHEREx, as well as the Mars gravity assist of Europa Clipper (artist’s concept).NASA/JPL-Caltech/BAE Systems/Lockheed Martin Space Missions will study everything from water on the Moon to the transformation of our universe after the big bang and ongoing changes to Earth’s surface.
With 2024 receding into the distance, NASA’s Jet Propulsion Laboratory is already deep into a busy 2025. Early in the new year, the Eaton Fire came close to JPL, destroying the homes of more than 200 employees, but work has continued apace to maintain mission operations and keep upcoming missions on track.
Several missions managed by NASA JPL are prepping for launch this year. Most have been years in the making and launches are, of course, only part of the bigger picture. Other milestones are also on the docket for the federal laboratory, which Caltech manages for NASA.
Here’s a glimpse of what lies ahead this year.
Mysterious Universe
Shaped like the bell of a trumpet and as big as a subcompact car, NASA’s SPHEREx space observatory is aiming for the stars. Known formally as the Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer, the mission will create four 3D maps of the entire sky in order to improve humanity’s understanding of the universe — how it expanded after the big bang, where ingredients of life can be found in ice grains, and much more. Target launch date: no earlier than Feb. 27 from Vandenberg Space Force Base in California.
The Moon’s Icy Secrets
NASA’s Lunar Trailblazer aims to help resolve an enduring mystery: Where is the Moon’s water? Scientists have seen signs suggesting it exists even where temperatures soar on the lunar surface, and there’s good reason to believe it can be found as surface ice in permanently shadowed craters, places that have not seen direct sunlight for billions of years. Managed by NASA JPL and led by Caltech, the small satellite will help provide answers, mapping the Moon’s surface water in unprecedented detail to determine the water’s abundance, location, form, and how it changes over time. The small satellite will hitch a ride, slated for late February, on the same launch as the Intuitive Machines-2 delivery to the Moon through NASA’s CLPS (Commercial Lunar Payload Services) initiative.
Earth’s Changing Surface
A collaboration between the United States and India, NISAR is a major addition to the fleet of satellites studying our changing planet. Short for NASA-Indian Space Research Organisation Synthetic Aperture Radar, the mission’s name is a nesting doll of acronyms, and the spacecraft is a nesting doll of capabilities: The first spacecraft to carry both L-band and S-band radars, it will see surface changes related to volcanoes, earthquakes, ice sheet motion, deforestation, and more in unprecedented detail after it launches in a few months’ time.
Sea Level
Targeting a November launch, Sentinel-6B will provide global sea surface height measurements — some of the most accurate data of its kind yet — that will improve climate models and hurricane tracking, as well as our understanding of phenomena like El Niño. A collaboration between NASA and ESA (European Space Agency), the spacecraft will take the baton from its twin, Sentinel-6 Michael Freilich, which launched in 2020. Together, the satellites are extending for another 10 years a nearly three-decade record of global sea surface height.
Moon Rover Trio
As a technology demonstration, the CADRE (Cooperative Autonomous Distributed Robotic Exploration) project marks another step NASA is taking toward developing robots that, by operating autonomously, can boost the efficiency of future missions. The project team at JPL will soon be packing up and shipping CADRE’s three suitcase-size rovers to Texas in preparation for their journey to the Moon aboard a commercial lander through one of NASA’s future CLPS deliveries. The rovers are designed to work together as a team without direct input from mission controllers back on Earth. And, by taking simultaneous measurements from multiple locations, they are meant to show how multirobot missions could enable new science and support astronauts.
Quantum Technology
Having arrived at the International Space Station in November, SEAQUE (Space Entanglement and Annealing QUantum Experiment) is testing two technologies that, if successful, could enable communication using entangled photons between two quantum systems. The research from this experiment, which gets underway in 2025, could help develop the building blocks for a future global quantum network that would allow equipment such as quantum computers to transfer data securely across large distances.
Gravity Assist to Reach Jupiter
Launched this past October, Europa Clipper will arrive at Jupiter in 2030 to investigate whether an ocean beneath the ice shell of the gas giant’s moon Europa has conditions suitable for life. The spacecraft will travel 1.8 billion miles (2.9 billion kilometers) to reach its destination. Since there are limitations on how much fuel the spacecraft can carry, mission planners are having Europa Clipper fly by Mars on March 1, using the planet’s gravity as a slingshot to add speed to its journey.
