A gentle rumble ran under a researcher's feet as a rocket carrying her research -- live, human muscle cells grown on scaffolds fixed on tiny chips -- lifted off, climbed, and disappeared into the sky...
View ArticleNASA's Fermi finds new feature in brightest gamma-ray burst yet seen
In October 2022, astronomers were stunned by what was quickly dubbed the BOAT -- the brightest-of-all-time gamma-ray burst (GRB). Now an international science team reports that data from NASA's Fermi...
View ArticleThe corona is weirdly hot: Parker Solar Probe rules out one explanation
By diving into the sun's corona, NASA's Parker Solar Probe has ruled out S-shaped bends in the sun's magnetic field as a cause of the corona's searing temperatures.
View ArticleScientists devise method to secure Earth's biodiversity on the moon
New research led proposes a plan to safeguard Earth's imperiled biodiversity by cryogenically preserving biological material on the moon. The moon's permanently shadowed craters are cold enough for...
View ArticleKey to rapid planet formation
Researchers have developed a new model to explain the formation of giant planets such as Jupiter, which furnishes deeper insights into the processes of planet formation and could expand our...
View ArticleScientists pin down the origins of the moon's tenuous atmosphere
Scientists say they have identified the main process that formed the moon's atmosphere and continues to sustain it today. The team reports that the lunar atmosphere is primarily a product of 'impact...
View ArticleAstronomers uncover risks to planets that could host life
A groundbreaking study has revealed that red dwarf stars can produce stellar flares that carry far-ultraviolet (far-UV) radiation levels much higher than previously believed.
View ArticleScientists lay out revolutionary method to warm Mars
Ever since we learned that the surface of planet Mars is cold and dead, people have wondered if there is a way to make it friendlier to life. The newly proposed method is over 5,000 times more...
View ArticleFindings from first archaeology project in space
The first-ever archeological survey in space has provided new insights into how astronauts use and adapt their living space on the International Space Station, which could influence the design of new...
View ArticleInternational Space Station crew carries out archeological survey in space
An archaeological strategy adapted for space used daily photos to reveal how astronauts actually use areas aboard the International Space Station -- and how this differs from intended uses.
View ArticleScientists find oceans of water on Mars: It's just too deep to tap
Quakes and meteor impacts on Mars generate seismic waves that can help map the interior. A new study analyzed seismic waves detected by the Insight lander and concludes that 11-20 kilometers beneath...
View ArticleEngineers make tunable, shape-changing metamaterial inspired by vintage toys
Common push puppet toys in the shapes of animals and popular figures can move or collapse with the push of a button at the bottom of the toys' base. Now, a team of engineers has created a new class of...
View ArticleMeasuring Martian winds with sound
Martian landers have been able capture measurements of wind speeds -- some gauging the cooling rate of heated materials when winds blow over them, others using cameras to image 'tell-tales' that blow...
View ArticleSwRI-led team finds evidence of hydration on Asteroid Psyche
Using data from NASA's James Webb Space Telescope, astronomers have confirmed hydroxyl molecules on the surface of the metallic asteroid Psyche. The presence of hydrated minerals suggests a complex...
View ArticleRocks from Mars' Jezero Crater, which likely predate life on Earth, contain...
Scientists report that rock samples from Mars' Jezero Crater contain minerals that are typically formed in water. While the presence of organic matter is inconclusive, the rocks could be scientists'...
View ArticleRocks collected on Mars hold key to water and perhaps life on the planet:...
Between July and November of 2022, NASA's Perseverance rover collected seven samples of sediment from an ancient alluvial fan in Jezero crater. While onboard analysis gave researchers some information...
View ArticleEngineers conduct first in-orbit test of 'swarm' satellite autonomous navigation
With 2D cameras and space robotics algorithms, astronautics engineers have created a navigation system able to manage multiple satellites using visual data only. They just tested it in space for the...
