NASA has officially released a spectacular image of one of the first solar flares of 2015. On Jan. 12, 2015, the sun emitted a mid-level solar flare that peaked at 11:24 EST.
There are several hazards when it comes to space travel, and one of them is muscle and bone loss. Now, a tiny roundworm may help keep astronauts healthy on long-duration space missions.
Scientists have used NASA's Cassini's spacecraft and the National Science Foundation's Very Long Baseline Array (VLBA) radio-telescope system to pinpoint the position of Saturn and its moons to within two miles.
Scientists have managed to create a unique map of enigmatic molecules in our galaxy that are responsible for puzzling features in the light from stars
In theory, if you sweep a laser pointer across the moon fast enough, you can cast spots that move faster than light across the surface. Now, scientists have reported that this theoretical curiosity may be practically useful out in the cosmos.
Astronomers may have succeeding in measuring the space-time warp in the gravity of a binary star. They've managed to determine the mass of a neutron star just before it vanished from view in a race against time.
Astronomers have taken a closer look at the nearby Andromeda galaxy and have made some startling discoveries. They've found striking differences from our own Milky Way, suggesting a much more violent history of mergers with smaller galaxies.
Many astronomers use powerful telescopes to target far-off objects in the distant universe. Now, though, one team is taking a different approach. They're using small telescopes to study a growing portion of the nearby universe all at once.
Scientists may have found evidence of two supermassive black holes colliding.
Physicists have proposed a new parallel universe theory that will boggle your mind.
NASA has captured some surprising and spectacular activity from the Superstar Eta Carinae. Now, they've used new 3D models that reveal never-before-seen features of the stars' interactions as decade-old shells of ionized gas race away from Eta Carinae at a million miles per hour.
Citizen scientists are making more and more discoveries each day. Now, a NASA-sponsored website designed to crowdsource analysis of data from the agency's Wide-field Infrared Survey Explorer (WISE) mission has reached a new milestone.
