An open cluster of stars shines through misty, cocoon-like gas clouds in this Hubble Space Telescope image of NGC 460.
NGC 460 is located in a region of the Small Magellanic Cloud, a dwarf galaxy that orbits the Milky Way. This particular region contains a number of young star clusters and nebulae of different sizes ― all likely related to each other. The clouds of gas and dust can give rise to stars as portions of them collapse, and radiation and stellar winds from those hot, young bright stars in turn shape and compress the clouds, triggering new waves of star formation. The hydrogen clouds are ionized by the radiation of nearby stars, causing them to glow.
The NGC 460 star cluster resides in one of the youngest parts of this interconnected complex of stellar clusters and nebulae, which is also home to a number of O-type stars: the brightest, hottest and most massive of the normal, hydrogen-burning stars (called main-sequence stars) like our Sun. O-type stars are rare ― out of more than 4 billion stars in the Milky Way, only about 20,000 are estimated to be O-type stars. The area that holds NGC 460, known as N83, may have been created when two hydrogen clouds in the region collided with one another, creating several O-type stars and nebulae.
Open clusters like NGC 460 are made of anywhere from a few dozen to a few thousand stars loosely knitted together by gravity. Open clusters generally contain young stars, which may migrate outward into their galaxies as time progresses. NGC 460’s stars may someday disperse into the Small Magellanic Cloud, one of the Milky Way’s closest galactic neighbors at about 200,000 light-years away. Because it is both close and bright, it offers an opportunity to study phenomena that are difficult to examine in more distant galaxies.
Six overlapping observations from a study of the gas and dust between stars, called the interstellar medium, were combined to create this Hubble image. The study aims to understand how gravitational forces between interacting galaxies can foster bursts of star formation.

Intuitive Machines’ IM-2 captured an image March 6, 2025, after landing in a crater from the Moon’s South Pole. The lunar lander is on its side about 820 feet from the intended landing site, Mons Mouton. In the center of the image between the two lander legs is the Polar Resources Ice Mining Experiment 1 suite, which shows the drill deployed.Credit: Intuitive Machines Shortly after touching down inside a crater on the Moon, carrying NASA technology and science on its IM-2 mission, Intuitive Machines collected some data for the agency before calling an early end of mission at 12:15 a.m. CST Friday.
As part of the company’s second Moon delivery for NASA under the agency’s CLPS (Commercial Lunar Payload Services) initiative and Artemis campaign, the IM-2 mission included a drill to bring lunar soil to the surface and a mass spectrometer to look for the presence of volatiles, or gases, that could one day help provide fuel or breathable oxygen to future Artemis explorers.
Planned to land at Mons Mouton, IM-2 touched down at approximately 11:30 a.m. March 6, more than 1,300 feet (400 meters) from its intended landing site. Intuitive Machines said images collected later confirmed the lander was on its side, preventing it from fully operating the drill and other instruments before its batteries were depleted.
The IM-2 mission landed closer to the lunar South Pole than any previous lander.
“Our targeted landing site near the lunar South Pole is one of the most scientifically interesting, and geographically challenging locations, on the Moon,” said Nicky Fox, associate administrator for science at NASA Headquarters in Washington. “Each success and setback are opportunities to learn and grow, and we will use this lesson to propel our efforts to advance science, exploration, and commercial development as we get ready for human exploration of Mars.”
The Nova-C lander, named Athena, captured and transmitted images of the landing site before activating the technology and science instruments. Among the data collected, NASA’s PRIME-1 (Polar Resources Ice Mining Experiment 1) suite, which includes the lunar drill known as TRIDENT (The Regolith and Ice Drill for Exploring New Terrain), successfully demonstrated the hardware’s full range of motion in the harsh environment of space. The Mass Spectrometer Observing Lunar Operations (MSOLO) as part of the PRIME-1 suite of instruments, detected elements likely due to the gases emitted from the lander’s propulsion system.
“While this mission didn’t achieve all of its objectives for NASA, the work that went into the payload development is already informing other agency and commercial efforts,” said Clayton Turner, associate administrator for space technology, NASA Headquarters. “As we continue developing new technologies to support exploration of the Moon and Mars, testing technologies in-situ is crucial to informing future missions. The CLPS initiative remains an instrumental method for achieving this.”
Despite the lander’s configuration, Intuitive Machines, which was responsible for launch, delivery, and surface operations under its CLPS contract, was able to complete some instrument checkouts and collect 250 megabytes of data for NASA.
“Empowering American companies to deliver science and tech to the Moon on behalf of NASA both produces scientific results and continues development of a lunar economy,” said Joel Kearns, deputy associate administrator for Exploration in the Science Mission Directorate at NASA Headquarters. “While we’re disappointed in the outcome of the IM-2 mission, we remain committed to supporting our commercial vendors as they navigate the very difficult task of landing and operating on the Moon.”
NASA’s Laser Retroreflector Array, a passive instrument meant to provide a reference point on the lunar surface and does not power on, will remain affixed to the top deck of the lander. Although Intuitive Machines’ Nova-C Hopper and Nokia’s 4G/LTE Tipping Point technologies, funded in part by NASA, were only able to complete some objectives, they provided insight into maturing technologies ready for infusion into a commercial space application including some checkouts in flight and on the surface.
Intuitive Machines’ IM-2 mission launched at 6:16 p.m., Feb. 26, aboard a SpaceX Falcon 9 rocket from Launch Complex 39A at the agency’s Kennedy Space Center in Florida.
Intuitive Machines has two more deliveries on the books for NASA in the future, with its IM-3 mission slated for 2026, and IM-4 mission in 2027.
To date, five vendors have been awarded a total of 11 lunar deliveries under CLPS and are sending more than 50 instruments to various locations on the Moon, including the Moon’s far side and South Pole region. CLPS contracts are indefinite-delivery/indefinite-quantity contracts with a cumulative maximum contract value of $2.6 billion through 2028.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Dwane Roth (right), a fourth generation grain farmer in Finney County, Kansas, stands with nephew Zion (left) in one of their corn fields. Roth’s farm became one of the first Water Technology Farms in Kansas around 2016, and he has been using OpenET data for the past few years to track evapotranspiration rates and conserve water. Photo courtesy of Dwane Roth A NASA and U.S. Geological Survey (USGS)-supported research and development team is making it easier for farmers and ranchers to manage their water resources.
The team, called OpenET, created the Farm and Ranch Management Support (FARMS) tool, which puts timely, high-resolution water data directly in the hands of individuals and small farm operators. By making the information more accessible, the platform can better support decision-making around agricultural planning, water conservation, and water efficiency. The OpenET team hopes this will help farmers who are working to build greater resiliency in local and regional agriculture communities. build greater resiliency in local and regional agriculture communities.
“It’s all about finding new ways to make satellite data easier to access and use for as many people as possible,” said Forrest Melton, the OpenET project scientist at NASA’s Ames Research Center in Silicon Valley. “The goal is to empower users with actionable, science-based data to support decisions about water management across the West.”

OpenET Data Explorer Tool: The Road to FARMS
The OpenET data explorer tool centers on providing evapotranspiration data. Evapotranspiration (ET) refers to the amount of water leaving Earth’s surface and returning to the atmosphere through evaporation (from soil and surface water) and transpiration (water vapor released by crops and other plants). Evapotranspiration is an important factor in agriculture, water resource management, irrigation planning, drought monitoring, and fire risk evaluation.
The FARMS resource is the third phase of OpenET’s Data Explorer tool, launched in 2021, which uses satellite data to quantify evapotranspiration across the western U.S.
It starts with using Landsat data to measure patterns in land surface temperature and key indicators of vegetation conditions. The satellite data is combined with agricultural data, such as field boundaries, and weather data, such as air temperature, humidity, solar radiation, wind speed, and precipitation. All of these factors feed into a model, which calculates the final evapotranspiration data.
The new FARMS interface was designed to make that data easier to access, with features that meet specific needs identified by users.
“This amount of data can be complicated to use, so user input helped us shape FARMS,” said Jordan Harding, app developer and interface design leader from HabitatSeven. “It provides a mobile-friendly, map-based web interface designed to make it easy as possible to get automated, regular reports.”
Top: A section of the 2024 annual report Roth submits to the Farm Service Agency, with hand-written annotations marking which crop will be grown that year. Bottom: Those same fields in the new OpenET FARMS interface, with a dashboard on the left displaying evapotranspiration data over the course of 2024 at monthly intervals. Each color line corresponds to the same color field on the map, showcasing how much evapotranspiration rates can differ between different crops in the same vicinity. The unique shape of the purple field (forage sorghum), is an example of a case where FARMS’ custom shape feature is helpful. Once the initial report is set up, Roth can re-run reports for the same fields at any time. NASA/OpenET “The FARMS tool is designed to help farmers optimize irrigation timing and amounts, simplify planning for the upcoming irrigation season, and automate ET and water use reporting,” said Sara Larsen, CEO of OpenET. “All of this reduces waste, lowers costs, and informs crop planning.”
Although FARMS is geared towards agriculture, the tool has value for other audiences in the western U.S. Land managers who evaluate the impacts of wildfire can use it to evaluate burn scars and changes to local hydrology. Similarly, resource managers can track evapotranspiration changes over time to evaluate the effectiveness of different forest management plans.
New Features in FARMS
To develop FARMS, the OpenET team held listening sessions with farmers, ranchers, and resource managers. One requested function was support for field-to-field comparisons; a feature for planning irrigation needs and identifying problem areas, like where pests or weeds may be impacting crop yields.
The tool includes numerous options for drawing or selecting field boundaries, generating custom reports based on selected models and variables, and automatically re-running reports at daily or monthly intervals.
The fine spatial resolution and long OpenET data record behind FARMS make these features more effective. Many existing global ET data products have a pixel size of over half a mile, which is too big to be practical for most farmers and ranchers. The FARMS interface provides insights at the scale of a quarter-acre per pixel, which offers multiple data points within an individual field.
“If I had told my father about this 15 years ago, he would have called me crazy,” said Dwane Roth, a fourth-generation farmer in Kansas. “Thanks to OpenET, I can now monitor water loss from my crops in real-time. By combining it with data from our soil moisture probes, this tool is enabling us to produce more food with less water. It’s revolutionizing agriculture.”
The FARMS mobile interface displays a six-year evapotranspiration report of a pear orchard owned by sixth-generation California farmer Brett Baker. The purple line in the dashboard report (left) corresponds with the field selected in purple on the map view (right), which users can toggle between using the green buttons in the top right corners. Running multi-year reports allows farmers to review historical trends.NASA/OpenET For those like sixth-generation California pear farmer Brett Baker, the 25-year span of ET data is part of what makes the tool so valuable. “My family has been farming the same crop on the same piece of ground for over 150 years,” Baker said. “Using FARMS gives us the ability to review historical trends and changes to understand what worked and what didn’t year to year: maybe I need to apply more fertilizer to that field, or better weed control to another. Farmers know their land, and FARMS provides a new tool that will allow us to make better use of land and resources.”
According to Roth, the best feature of the tool is intangible. “Being a farmer is stressful,” Roth said. “OpenET is beneficial for the farm and the agronomic decisions, but I think the best thing it gives me is peace of mind.”

Continuing Evolution of FARMS
Over the coming months, the OpenET team plans to present the new tool at agricultural conferences and conventions in order to gather feedback from as many users as possible. “We know that there is already a demand for a seven-day forecast of ET, and I’m sure there will be requests about the interface itself,” said OpenET senior software engineer Will Carrara. “We’re definitely looking to the community to help us further refine that platform.”
“I think there are many applications we haven’t even thought of yet,” Baker added. “The FARMS interface isn’t just a tool; it’s an entirely new toolbox itself. I’m excited to see what people do with it.”
FARMS was developed through a public-private collaboration led by NASA, USGS, USDA, the non-profit OpenET, Inc., Desert Research Institute, Environmental Defense Fund, Google Earth Engine, HabitatSeven, California State University Monterey Bay, Chapman University, Cornell University, University of Nebraska-Lincoln, UC Berkeley and other universities, with input from more than 100 stakeholders.

NASA Open Data Turns Science Into Art
Guests enjoy Beyond the Light, a digital art experience featuring open NASA data, at ARTECHOUSE in Washington, D.C. on September 19, 2023. NASA/Wade Sisler An art display powered by NASA science data topped the Salesforce Tower in San Francisco, CA throughout December 2024. Nightly visitors enjoyed “Synchronicity,” a 20-minute-long video art piece by Greg Niemeyer, which used a year’s worth of open data from NASA satellites and other sources to bring the rhythms of the Bay Area to life.
Data for “Synchronicity” included atmospheric data from NASA and NOAA’s GOES (Geostationary Operational Environmental Satellites), vegetation health data from NASA’s Landsat program, and the Sun’s extreme ultraviolet wavelengths as captured by the NASA and ESA (European Space Agency) satellite SOHO (Solar and Heliospheric Observatory). Chelle Gentemann, the program scientist for the Office of the Chief Science Data Officer within NASA’s Science Mission Directorate, advised Niemeyer on incorporating data into the piece.

Greg Niemeyer’s “Synchronicity” was displayed on Salesforce Tower in San Francisco, CA, in December 2024. A recording of the piece on the tower’s display and the original animation are shown here. The video art piece was created using open NASA data, as well as buoy data from the National Oceanographic and Atmospheric Administration (NOAA). Greg Niemeyer/Emma Strebel “Artists have a lot to contribute to science,” Gentemann said. “Not only can they play a part in the actual scientific process, looking at things in a different way that will lead to new questions, but they’re also critical for getting more people involved in science.”
NASA’s history of engaging with artists goes back to the 1962 launch of the NASA Art Program, which partnered with artists in bringing the agency’s achievements to a broader audience and telling the story of NASA in a different and unexpected way. Artists such as Andy Warhol, Norman Rockwell, and Annie Leibovitz created works inspired by NASA missions. The Art Program was relaunched in September 2024 with a pair of murals evoking the awe of space exploration for the Artemis Generation.
The inaugural murals for the relaunched NASA Art Program appear side-by-side at 350 Hudson Street, Monday, Sept. 23, 2024, in New York City. The murals, titled “To the Moon, and Back,” were created by New York-based artist team Geraluz and WERC and use geometrical patterns to invite deeper reflection on the exploration, creativity, and connection with the cosmos. NASA/Joel Kowsky The use of NASA data in art pieces emerged a few decades after the NASA Art Program first launched. Several in-house agency programs, such as NASA’s Scientific Visualization Studio, create stunning animated works from science data. In the realm of audio, NASA’s Chandra X-ray Observatory runs the Universe of Sound project to convert astronomy data into “sonifications” for the public’s listening pleasure.
Collaborations with external artists help bring NASA data to an even broader audience. NASA’s commitment to open science – making it as easy as possible for the public to access science data – greatly reduces the obstacles for creatives looking to fuse their art with cutting-edge science.
Michelle Thaller, assistant director for science communication at Goddard, presents the “Pillars of Creation” in the Eagle nebula to the ARTECHOUSE team during a brainstorming session at Goddard. The left image is a view from the Hubble Space Telescope, and the right view is from the Webb telescope. NASA/Wade Sisler Another recent blend of NASA data and art came when digital art gallery ARTECHOUSE created “Beyond the Light,” a 26-minute immersive video experience featuring publicly available images from the James Webb Space Telescope and Hubble Space Telescope. The experience has been running at various ARTECHOUSE locations since September 2023. The massive potential for art to incorporate science data promises to fuel even more of these collaborations between NASA and artists in the future.
“One of the integral values of open science is providing opportunities for more people to participate in science,” Gentemann said. “I think that by getting the public interested in how this art is done, they also are starting to play with scientific data, maybe for the first time. In that way, art has the power to create new scientists.”

NASA, CXC, NRAO, ESA, M. McDonald (MIT), M. Reefe (MIT), J. Olmsted (STScI) Discovery proves decades-old theory of galaxy feeding cycle.
Researchers using NASA’s James Webb Space Telescope have finally solved the mystery of how a massive galaxy cluster is forming stars at such a high rate. The confirmation from Webb builds on more than a decade of studies using NASA’s Chandra X-ray Observatory and Hubble Space Telescope, as well as several ground-based observatories.
The Phoenix cluster, a grouping of galaxies bound together by gravity 5.8 billion light-years from Earth, has been a target of interest for astronomers due to a few unique properties. In particular, ones that are surprising: a suspected extreme cooling of gas and a furious star formation rate despite a roughly 10 billion solar mass supermassive black hole at its core. In other observed galaxy clusters, the central supermassive black hole powers energetic particles and radiation that prevents gas from cooling enough to form stars. Researchers have been studying gas flows within this cluster to try to understand how it is driving such extreme star formation.
Image A: Phoenix Cluster (Hubble, Chandra, VLA Annotated)
Spectroscopic data collected from NASA’s James Webb Space Telescope is overlayed on an image of the Phoenix cluster that combines data from NASA’s Hubble Space Telescope, Chandra X-ray Observatory and the Very Large Array (VLA) radio telescope. Webb’s powerful sensitivity in the mid-infrared detected the cooling gas that leads to a furious rate of star formation in this massive galaxy cluster. Credit: NASA, CXC, NRAO, ESA, M. McDonald (MIT), M. Reefe (MIT), J. Olmsted (STScI) “We can compare our previous studies of the Phoenix cluster, which found differing cooling rates at different temperatures, to a ski slope,” said Michael McDonald of the Massachusetts Institute of Technology in Cambridge, principal investigator of the program. “The Phoenix cluster has the largest reservoir of hot, cooling gas of any galaxy cluster — analogous to having the busiest chair lift, bringing the most skiers to the top of the mountain. However, not all of those skiers were making it down the mountain, meaning not all the gas was cooling to low temperatures. If you had a ski slope where there were significantly more people getting off the ski lift at the top than were arriving at the bottom, that would be a problem!”
To date, in the Phoenix cluster, the numbers weren’t adding up, and researchers were missing a piece of the process. Webb has now found those proverbial skiers at the middle of the mountain, in that it has tracked and mapped the missing cooling gas that will ultimately feed star formation. Most importantly, this intermediary warm gas was found within cavities tracing the very hot gas, a searing 18 million degrees Fahrenheit, and the already cooled gas around 18,000 degrees Fahrenheit.
The team studied the cluster’s core in more detail than ever before with the Medium-Resolution Spectrometer on Webb’s Mid-Infrared Instrument (MIRI). This tool allows researchers to take two-dimenstional spectroscopic data from a region of the sky, during one set of observations.
“Previous studies only measured gas at the extreme cold and hot ends of the temperature distribution throughout the center of the cluster,” added McDonald. “We were limited — it was not possible to detect the ‘warm’ gas that we were looking for. With Webb, we could do this for the first time.”
Image B: Phoenix Cluster (Hubble, Chandra, VLA)
This image of the Phoenix cluster combines data from NASA’s Hubble Space Telescope, Chandra X-ray Observatory, and the Very Large Array radio telescope. X-rays from Chandra depict extremely hot gas in purple. Optical light data from Hubble show galaxies in yellow, and filaments of cooler gas where stars are forming in light blue. Outburst generated jets, represented in red, are seen in radio waves by the VLA radio telescope. NASA, CXC, NRAO, ESA, M. McDonald (MIT). A Quirk of Nature
Webb’s capability to detect this specific temperature of cooling gas, around 540,000 degrees Fahrenheit, is in part due to its instrumental capabilities. However, the researchers are getting a little help from nature, as well.
This oddity involves two very different ionized atoms, neon and oxygen, created in similar environments. At these temperatures, the emission from oxygen is 100 times brighter but is only visible in ultraviolet. Even though the neon is much fainter, it glows in the infrared, which allowed the researchers to take advantage of Webb’s advanced instruments.
“In the mid-infrared wavelengths detected by Webb, the neon VI signature was absolutely booming,” explained Michael Reefe, also of the Massachusetts Institute of Technology, lead author on the paper published in Nature. “Even though this emission is usually more difficult to detect, Webb’s sensitivity in the mid-infrared cuts through all of the noise.”
The team now hopes to employ this technique to study more typical galaxy clusters. While the Phoenix cluster is unique in many ways, this proof of concept is an important step towards learning about how other galaxy clusters form stars.The James Webb Space Telescope is the world’s premier space science observatory. Webb 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).
