The latest news briefs from NASA science.
Massive stars are often known to go out with a bang: The core collapses, and a wave of subatomic particles called neutrinos erupt outward, causing the star to explode as a supernova that can outshine an entire galaxy. But 2.5 million light-years away from Earth, in the Andromeda galaxy, a dying star named M31-2014-DS1 did […]
The thermal infrared capabilities of an imager on NASA’s Terra satellite have been shut off and will no longer collect data, more than 25 years after the instrument captured its first image of Earth from space. This is the latest effort to prioritize power on Terra for its remaining instruments. Terra, which had a design […]
In a new study, researchers say that non-biological sources they considered could not fully account for the abundance of organic compounds in a sample collected on Mars by NASA’s Curiosity rover. In March 2025, scientists reported identifying small amounts of decane, undecane, and dodecane in a rock sample analyzed in the chemistry lab aboard Curiosity. […]
Data from NASA’s Juno mission has revealed that the solar system’s largest planet is slightly smaller and more “squashed” than previously believed. By analyzing radio occultation data from 13 flybys of Jupiter and incorporating the effects of zonal winds, mission scientists have determined that Jupiter is about 5 miles (8 kilometers) narrower at the equator and 15 miles (24 […]
Scouring archived observations from NASA missions, scientists may have solved a mystery about what powers a type of aurora called auroral arcs. The answer, they say, is space waves. From the ground, auroral arcs look like green, glowing curtains of light sweeping across the night sky. From space, they appear as thin, green lines — or arcs — slicing across the […]
New analysis of decades-old data has turned up a significant result: the first discovery of ammonia-bearing compounds on the surface of Jupiter’s moon Europa. Ammonia is a nitrogen-bearing molecule, and nitrogen — like carbon, hydrogen, and oxygen — is key to life as we know it. As the first such detection at Europa, the finding […]
Science teams at NASA and the French space agency CNES (Centre National d’Études Spatiales) have released the first-ever global estimate of river discharge and suspended sediment, as observed from space, marking a new milestone in our ability to understand one of Earth’s most fundamental systems. Developed using data from the SWOT (Surface Water and Ocean […]
NASA’s Tropospheric Emissions: Monitoring of Pollution instrument, or TEMPO, is known for measuring trace gases like nitrogen dioxide, ozone, and formaldehyde in the air we breathe. Now TEMPO has a new trick. It can see in the dark. Since launching in 2023, TEMPO data has set a record at the Atmospheric Science Data Center (ASDC) […]
All 48 contiguous United States will now benefit from timely, high-resolution water data. The OpenET program, a public-private collaboration led by consortium partners NASA, the U.S. Geological Survey, California State University Monterey Bay, Environmental Defense Fund, Desert Research Institute, Google Earth Engine, and HabitatSeven, provides information on evapotranspiration. Evapotranspiration is the movement of water from […]
