NASA-supported scientists have resurrected an enzyme first used by organisms on Earth 3.2-billion years ago and, in the process, have validated a chemical biosignature in rocks that is used to understand ancient life on Earth. The research provides a new understanding of what Earth’s biosphere was like early in our planet’s history and confirms a […]

Flight Engineers Give NASA’s Dragonfly Lift
In sending a car-sized rotorcraft to explore Saturn’s moon Titan, NASA’s Dragonfly mission will undertake an unprecedented voyage of scientific discovery. And the work to ensure that this first-of-its-kind project can fulfill its ambitious exploration vision is underway in some of the nation’s most advanced space simulation and testing laboratories. Set for launch in in […]
NASA Study Suggests Saturn’s Moon Titan May Not Have Global Ocean
A key discovery from NASA’s Cassini mission in 2008 was that Saturn’s largest moon Titan may have a vast water ocean below its hydrocarbon-rich surface. But reanalysis of mission data suggests a more complicated picture: Titan’s interior is more likely composed of ice, with layers of slush and small pockets of warm water that form […]
Sugars, ‘Gum,’ Stardust Found in NASA’s Asteroid Bennu Samples
The asteroid Bennu continues to provide new clues to scientists’ biggest questions about the formation of the early solar system and the origins of life. As part of the ongoing study of pristine samples delivered to Earth by NASA’s OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer) spacecraft, three new papers published Tuesday by […]

NASA Cassini Study Finds Organics ‘Fresh’ From Ocean of Enceladus
Researchers dove deep into information gathered from the ice grains that were collected during a close and super-fast flyby through a plume of Saturn’s icy moon. A new analysis of data from NASA’s Cassini mission found evidence of previously undetected organic compounds in a plume of ice particles ejected from the ocean that lies under […]

From City Lights to Moonlight: NASA Training Shows How Urban Parks Can Connect Communities with Space Science
When you think about national park and public land astronomy programs, you might picture remote locations far from city lights. But a recent NASA Earth to Sky training, funded by NASA’s Science Activation Program, challenges that assumption, demonstrating how urban parks, wildlife refuges, museums, and green spaces can be incredible venues for connecting communities with […]
NASA Says Mars Rover Discovered Potential Biosignature Last Year
Lee este comunicado de prensa en español aquí. A sample collected by NASA’s Perseverance Mars rover from an ancient dry riverbed in Jezero Crater could preserve evidence of ancient microbial life. Taken from a rock named “Cheyava Falls” last year, the sample, called “Sapphire Canyon,” contains potential biosignatures, according to a paper published Wednesday in the […]
