Even small asteroids lead complex lives. During its flyby of the asteroid Donaldjohanson last year, NASA’s Lucy spacecraft revealed the asteroid to be a wobbly, peanut-shaped body that has undergone a lot of activity in its relatively short history. Formed as fragments coalesced after a violent collision 155 million years ago, the asteroid was transformed by the […]
Researchers using two of humanity’s most powerful observatories — NASA’s James Webb and Hubble Space Telescopes — have definitively shown that Terzan 5 is not a globular star cluster as it was once classified, offering new insight into how galaxies like our own form and evolve over time. A globular star cluster typically has only […]
The complex puzzle known as little red dots has become more complete since their initial discovery by NASA’s James Webb Space Telescope in 2022. Now a particular little red dot’s spectrum is helping connect many of the pieces. A team of astronomers led by Vasily Kokorev at the University of Texas at Austin identified the […]
A compact, multifrequency radar built by a team at NASA’s Jet Propulsion Laboratory will make it easier to collect information about dynamic cloud systems. Called CloudCube, this new instrument simultaneously probes the atmosphere with three radar signals, spanning 36 to 240 GHz, for optimized sensitivity to a wide range of water droplet and ice particle sizes.
Which comes first, the galaxy or the black hole? We don’t know, but scientists have long thought it could be the galaxy: Large stars within an existing galaxy consume their fuel and collapse to form black holes, which can gobble up surrounding material and merge over time to form more massive entities. But it’s hard […]
NASA’s TESS has released its most complete view of the starry sky to date
A team of researchers demonstrated NASA and IBM’s open-source Prithvi Geospatial artificial intelligence foundation model aboard two in-orbit platforms.
After a recent count, NASA Citizen Science is proud to report that more than 650 people who have volunteered to participate in NASA citizen science projects have co-authored peer-reviewed research papers with scientists on those project teams. These volunteers made incredible contributions like: And all of them saw their passion and dedication translated into lasting […]
On every crewed mission, NASA packs pouches of a potentially life-saving liquid in its cargo, known as IV (or intravenous) fluid. A simple mix of sodium chloride and purified water, it can treat up to 30% of medical conditions in flight, resolving things like dehydration, burns, and more. Crewed missions beyond low Earth orbit into […]
Scientists have found that young stellar cousins of our Sun are calming down and dimming more quickly in their X-ray output than previously thought, according to a new study using NASA’s Chandra X-ray Observatory. A paper describing the results published Monday in The Astrophysical Journal. Unlike in the new movie “Project Hail Mary,” this quieting […]
