This artist’s illustration represents the results from a new study that examines the effects of X-ray and other high-energy radiation unleashed on potential exoplanets from Wolf 359, a nearby red dwarf star. Researchers used Chandra and XMM-Newton to study the impact of steady X-ray and energetic ultraviolet radiation from Wolf 359 on the atmospheres of planets that might be orbiting the star. They found that only a planet with greenhouse gases like carbon dioxide in its atmosphere and at a relatively large distance away from Wolf 359 would have a chance to support life as we know it.X-ray: NASA/CXC/SAO/S.Wolk, et al.; Illustration: NASA/CXC/SAO/M.Weiss; Image processing: NASA/CXC/SAO/N. Wolk Planets around other stars need to be prepared for extreme weather conditions, according to a new study from NASA’s Chandra X-ray Observatory and ESA’s (European Space Agency’s) XMM-Newton that examined the effects of X-rays on potential planets around the most common type of stars.
Astronomers found that only a planet with greenhouse gases in its atmosphere like Earth and at a relatively large distance away from the star they studied would have a chance to support life as we know it around a nearby star.
Wolf 359 is a red dwarf with a mass about a tenth that of the Sun. Red dwarf stars are the most common stars in the universe and live for billions of years, providing ample time for life to develop. At a distance of only 7.8 light-years away, Wolf 359 is also one of the closest stars to the solar system.
“Wolf 359 can help us unlock the secrets around stars and habitability,” said Scott Wolk of the Center for Astrophysics | Harvard & Smithsonian (CfA), who led the study. “It’s so close and it belongs to such an important class of stars – it’s a great combination.”
Because red dwarfs are the most prevalent types of stars, astronomers have looked hard to find exoplanets around them. Astronomers have found some evidence for two planets in orbit around Wolf 359 using optical telescopes, but those conclusions have been challenged by other scientists.
“While we don’t have proof of planets around Wolf 359 yet, it seems very possible that it hosts multiple planets,” Wolk added. “This makes it an excellent test bed to look at what planets would experience around this kind of star.”
Wolk and his colleagues used Chandra and XMM to study the amounts of steady X-rays and extreme ultraviolet (UV) radiation – the most energetic type of UV radiation – that Wolf 359 would unleash on the possible planets around it.
They found that Wolf 359 is producing enough damaging radiation that only a planet with greenhouse gases like carbon dioxide in its atmosphere – and located at a relatively large distance from the star – would likely be able to sustain life.
“Just being far enough away from the star’s harmful radiation wouldn’t be enough to make it habitable,” said co-author Vinay Kashyap, also of CfA. “A planet around Wolf 359 would also need to be blanketed in greenhouse gases like Earth is.”
To study the effects of energetic radiation on the habitability of the planet candidates, the team considered the star’s habitable zone – the region around a star where liquid water could exist on a planet’s surface.
The outer limit of the habitable zone for Wolf 359 is about 15% of the distance between Earth and the Sun, because the red dwarf is much less bright than the Sun. Neither of the planet candidates for this system is located in Wolf 359’s habitable zone, with one too close to the star and the other too far out.
“If the inner planet is there, the X-ray and extreme UV radiation it is subjected to would destroy the atmosphere of this planet in only about a million years,” said co-author Ignazio Pillitteri of CfA and the National Institute for Astrophysics in Palermo, Italy.
The team also considered the effects of radiation on as-yet undetected planets within the habitable zone. They concluded that a planet like the Earth in the middle of the habitable zone should be able to sustain an atmosphere for almost two billion years, while one near the outer edge could last indefinitely, helped by the warming effects of greenhouse gases.
Another big danger for planets orbiting stars like Wolf 359 is from X-ray flares, or occasional bright bursts of X-rays, on top of the steady, everyday output from the star. Combining observations made with Chandra and XMM-Newton resulted in the discovery of 18 X-ray flares from Wolf 359 over 3.5 days.
Extrapolating from these observed flares, the team expects that much more powerful and damaging flares would occur over longer periods of time. The combined effects of the steady X-ray and UV radiation and the flares mean that any planet located in the habitable zone is unlikely to have a significant atmosphere long enough for multicellular life, as we know it on Earth, to form and survive. The exception is the habitable zone’s outer edge if the planet has a significant greenhouse effect.
These results were presented at the 245th meeting of the American Astronomical Society in National Harbor, Maryland, and are being prepared for publication in a journal. 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.

5 Min Read NASA and Italian Space Agency Test Future Lunar Navigation Technology
The potentially record-breaking Lunar GNSS Receiver Experiment (LuGRE) payload will be the first known demonstration of GNSS signal reception on and around the lunar surface. Credits: NASA/Dave Ryan As NASA celebrates 55 years since the historic Apollo 11 crewed lunar landing, the agency also is preparing new navigation and positioning technology for the Artemis campaign, the agency’s modern lunar exploration program.
A technology demonstration helping pave the way for these developments is the Lunar GNSS Receiver Experiment (LuGRE) payload, a joint effort between NASA and the Italian Space Agency to demonstrate the viability of using existing GNSS (Global Navigation Satellite System) signals for positioning, navigation, and timing on the Moon.
During its voyage on an upcoming delivery to the Moon as part of NASA’s CLPS (Commercial Lunar Payload Services) initiative, LuGRE would demonstrate acquiring and tracking signals from both the U.S. GPS and European Union Galileo GNSS constellations during transit to the Moon, during lunar orbit, and finally for up to two weeks on the lunar surface itself.
The Lunar GNSS Receiver Experiment (LuGRE) will investigate whether signals from two Global Navigation Satellite System (GNSS) constellations, the U.S. Global Positioning System (GPS) and European Union’s Galileo, can be tracked at the Moon and used for positioning, navigation, and timing (PNT). The LuGRE payload is one of the first demonstrations of GNSS signal reception and navigation on and around the lunar surface, an important milestone for how lunar missions will access navigation and positioning technology. If successful, LuGRE would demonstrate that spacecraft can use signals from existing GNSS satellites at lunar distances, reducing their reliance on ground-based stations on the Earth for lunar navigation.
Today, GNSS constellations support essential services like navigation, banking, power grid synchronization, cellular networks, and telecommunications. Near-Earth space missions use these signals in flight to determine critical operational information like location, velocity, and time.
NASA and the Italian Space Agency want to expand the boundaries of GNSS use cases. In 2019, the Magnetospheric Multiscale (MMS) mission broke the world record for farthest GPS signal acquisition 116,300 miles from the Earth’s surface — nearly half of the 238,900 miles between Earth and the Moon. Now, LuGRE could double that distance.
“GPS makes our lives safer and more viable here on Earth,” said Kevin Coggins, NASA deputy associate administrator and SCaN (Space Communications and Navigation) Program manager at NASA Headquarters in Washington. “As we seek to extend humanity beyond our home planet, LuGRE should confirm that this extraordinary technology can do the same for us on the Moon.”
NASA, Firefly, Qascom, and Italian Space Agency team members examine LuGRE hardware in a clean room.Firefly Aerospace Reliable space communication and navigation systems play a vital role in all NASA missions, providing crucial connections from space to Earth for crewed and uncrewed missions alike. Using a blend of government and commercial assets, NASA’s Near Space and Deep Space Networks support science, technology demonstrations, and human spaceflight missions across the solar system.
“This mission is more than a technological milestone,” said Joel Parker, policy lead for positioning, navigation, and timing at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “We want to enable more and better missions to the Moon for the benefit of everyone, and we want to do it together with our international partners.”

The data-gathering LuGRE payload combines NASA-led systems engineering and mission management with receiver software and hardware developed by the Italian Space Agency and their industry partner Qascom — the first Italian-built hardware to operate on the lunar surface.
Any data LuGRE collects is intended to open the door for use of GNSS to all lunar missions, not just those by NASA or the Italian Space Agency. Approximately six months after LuGRE completes its operations, the agencies will release its mission data to broaden public and commercial access to lunar GNSS research.
Firefly Aerospace’s Blue Ghost Mission One lander is carrying 10 NASA science and technology instruments to the Moon as part of NASA’s CLPS (Commercial Lunar Payload Services) initiative and Artemis campaign.Firefly Aerospace “A project like LuGRE isn’t about NASA alone,” said NASA Goddard navigation and mission design engineer Lauren Konitzer. “It’s something we’re doing for the benefit of humanity. We’re working to prove that lunar GNSS can work, and we’re sharing our discoveries with the world.”
The LuGRE payload is one of 10 NASA-funded science experiments launching to the lunar surface on this delivery through NASA’s CLPS initiative. Through CLPS, NASA works with American companies to provide delivery and quantity contracts for commercial deliveries to further lunar exploration and the development of a sustainable lunar economy. As of 2024, the agency has 14 private partners on contract for current and future CLPS missions.
Demonstrations like LuGRE could lay the groundwork for GNSS-based navigation systems on the lunar surface. Bridging these existing systems with emerging lunar-specific navigation solutions has the potential to define how all spacecraft navigate lunar terrain in the Artemis era.

Funding and oversight for the LuGRE payload comes from the agency’s SCaN Program office. It was chosen by NASA as one of 10 funded research and technology demonstrations for delivery to the lunar surface by Firefly Aerospace Inc, a flight under the agency’s CLPS initiative.
