ESA/Hubble & NASA, R. Sankrit In this NASA/ESA Hubble Space Telescope image, Hubble once again lifts the veil on a famous — and frequently photographed — supernova remnant: the Veil Nebula. The remnant of a star roughly 20 times as massive as the Sun that exploded about 10,000 years ago, the Veil Nebula is situated about 2,400 light-years away in the constellation Cygnus. Hubble images of this photogenic nebula were first taken in 1994 and 1997, and again in 2015.
This view combines images taken in three different filters by Hubble’s Wide Field Camera 3, highlighting emission from hydrogen, sulfur, and oxygen atoms. The image shows just a small fraction of the Veil Nebula; if you could see the entire nebula without the aid of a telescope, it would be as wide as six full Moons placed side-by-side.
Although this image captures the Veil Nebula at a single point in time, it helps researchers understand how the supernova remnant evolves over decades. Combining this snapshot with Hubble observations from 1994 will reveal the motion of individual knots and filaments of gas over that span of time, enhancing our understanding of this stunning nebula.

CCOR-1, a newly activated coronagraph onboard NOAA’s GOES-19 weather satellite, is the first of its kind in geostationary orbit. Positioned deep inside the Moon’s orbit, it offers a perspective unavailable to previous coronagraphs like those on SOHO.
New Moons are typically dark and invisible, but NOAA's CCOR-1 coronagraph just captured one in stunning detail.
In the footage, the Moon appears full, an illusion caused entirely by sunlight reflecting off Earth. The brightness isn’t constant, though. As sunrise progresses over the Western Hemisphere, the increasing Earthshine becomes so intense that some frames are saturated with light.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
The Compact Fire Infrared Radiance Spectral tracker, or C-FIRST, is managed an operated by NASA’s Jet Propulsion Laboratory, and supported by NASA’s Earth Science Technology Office. Combining state-of-the-art imaging technology with a compact design, C-FIRST enables scientists to gather data about fires and their impacts on ecosystems with greater accuracy and speed than other instruments. C-FIRST was developed as a spaceborne instrument, and flew onboard NASA’s B200 aircraft in January 2025 to conduct an airborne test.NASA/JPL-Caltech The January wildfires in California devastated local habitats and communities. In an effort to better understand wildfire behavior, NASA scientists and engineers tried to learn from the events by testing new technology.
The new instrument, the Compact Fire Infrared Radiance Spectral Tracker (c-FIRST), was tested when NASA’s B200 King Air aircraft flew over the wildfires in the Pacific Palisades and Altadena, California. Based at NASA’s Armstrong Flight Research Center in Edwards, California, the aircraft used the c-FIRST instrument to observe the impacts of the fires in near real-time. Due to its small size and ability to efficiently simulate a satellite-based mission, the B200 King Air is uniquely suited for testing c-FIRST.
Managed and operated by NASA’s Jet Propulsion Laboratory in Southern California, c-FIRST gathers thermal infrared images in high-resolution and other data about the terrain to study the impacts of wildfires on ecology. In a single observation, c-FIRST can capture the full temperature range across a wide area of wildland fires – as well as the cool, unburned background – potentially increasing both the quantity and quality of science data produced.
“Currently, no instrument is able to cover the entire range of attributes for fires present in the Earth system,” said Sarath Gunapala, principal investigator for c-FIRST at NASA JPL. “This leads to gaps in our understanding of how many fires occur, and of crucial characteristics like size and temperature.”
For decades, the quality of infrared images has struggled to convey the nuances of high-temperature surfaces above 1,000 degrees Fahrenheit (550 degrees Celsius). Blurry resolution and light saturation of infrared images has inhibited scientists’ understanding of an extremely hot terrain, and thereby also inhibited wildfire research. Historically, images of extremely hot targets often lacked the detail scientists need to understand the range of a fire’s impacts on an ecosystem.
NASA’s Armstrong Flight Research Center in Edwards, California, flew the B200 King Air in support of the Signals of Opportunity Synthetic Aperture Radar (SoOpSAR) campaign on Feb. 27, 2023.NASA/Steve Freeman To address this, NASA’s Earth Science Technology Office supported JPL’s development of the c-FIRST instrument, combining state-of-the-art imaging technology with a compact and efficient design. When c-FIRST was airborne, scientists could detect smoldering fires more accurately and quickly, while also gathering important information on active fires in near real-time.
“These smoldering fires can flame up if the wind picks up again,” said Gunapala. “Therefore, the c-FIRST data set could provide very important information for firefighting agencies to fight fires more effectively.”
For instance, c-FIRST data can help scientists estimate the likelihood of a fire spreading in a certain landscape, allowing officials to more effectively monitor smoldering fires and track how fires evolve. Furthermore, c-FIRST can collect detailed data that can enable scientists to understand how an ecosystem may recover from fire events.
“The requirements of the c-FIRST instrument meet the flight profile of the King Air,” said KC Sujan, operations engineer for the B200 King Air. “The c-FIRST team wanted a quick integration, the flight speed in the range 130 and 140 knots on a level flight, communication and navigation systems, and the instruments power requirement that are perfectly fit for King Air’s capability.”
By first testing the instrument onboard the B200 King Air, the c-FIRST team can evaluate its readiness for future satellite missions investigating wildfires. On a changing planet where wildfires are increasingly common, instruments like c-FIRST could provide data that can aid firefighting agencies to fight fires more effectively, and to understand the ecosystemic impacts of extreme weather events.

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.”
