Understanding how fire spreads in a microgravity environment is critical to the safety of astronauts who live and work in space....

470 million years ago, somewhere in our Solar System, there was an enormous collision between two asteroids. We know this because of the rain of meteorites that struck Earth at that time. But inside that rain of meteorit...

The Milky Way turns out to be part of a massive supercluster of galaxies that forms one of the largest known structures in the universe. This discovery is only the beginning of a new effort to map... --

Northwestern University astrophysicists have predicted history. In a new study, the scientists show their theoretical predictions last year were correct: The historic merger of two massive black holes detected Sept. 14, ...

Gravitational waves from a second pair of colliding black holes has validated the landmark discovery from earlier this year that confirmed Einstein's general theory of relativity. Rochester Institute of Technology scient...

On December 26, 2015, at 03:38:53 UTC, scientists observed gravitational waves -- ripples in the fabric of spacetime -- for the second time....

"We consider the possibility that the black hole binary detected by LIGO may be a signature of dark matter," wrote eight scientists from the Johns Hopkins Henry A. Rowland Department of Physics and Astronomy in their sum...

On December 26, 2015 at 03:38:53 UTC, scientists observed gravitational waves--ripples in the fabric of spacetime--for the second time.

SpaceX successfully launched two satellites into orbit on Wednesday, but failed in an attempt to land the first stage of its Falcon 9 rocket undamaged on a barge in the Atlantic.

Canadian astronaut Chris Hadfield charmed the world with his guitar-playing during his stint as commander of the International Space Station.

The first stage of SpaceX's Falcon 9 rocket managed to hit its target -- a robotic "drone ship" stationed a few hundred miles off the Florida coast -- but wasn't able to stick the landing during the successful launch of ...

The protoplanetary disc around the young star TW Hydrae is the closest known example to Earth, at a distance of only about 170 light-years, closely resembling what astronomers think the Solar System looked like during it...

After launching 2 EUTELSAT satellites, the first stage of the Falcon 9 rocket engines were restarted for a controlled descent down to the "Of Course I Still Love You" robotic ship in the Atlantic Ocean.

On June 15, 2016, SpaceX launched the EUTELSAT 117 West B and ABS-2A communications satellites, and attempted to bring the first stage of its Falcon 9 rocket down for a landing on a ship at sea. See images here.

The EUTELSAT 117 West B and ABS-2A satellites were launched into geostationary transfer orbit On June 15, 2016 from Cape Canaveral Air Force Station.

A first of its kind alien rock has been excavated in a limestone quarry in Sweden, where it had lain deeply buried for about 470 million years, scientists said Tuesday. The biscuit-sized remains are unlike any other mete...

Caltech researchers have detected, for the first time, a chiral molecule outside of our solar system, bringing them one step closer to understanding one of the most puzzling mysteries of the early origins of life. By dis...

Expedition 47 robotic arm operator Tim Kopra of NASA commanded the International Space Station's Canadarm2 robotic arm to release the Cygnus spacecraft at 9:30 a.m. EDT while the space station was flying above Paraguay. ...

When a star dies, it can be lovely. When a star dies with another nearby, it can be amazing. The image above shows Hubble 12 (also called HB 12 for short), what astronomers call a planetary nebula, the gas and dust throw...
