For the first time, astronomers have observed in visible light a cataclysmic cosmic event that generated gravitational waves detected on Earth.

When two neutron stars collided on Aug. 17, a widespread search for electromagnetic radiation from the event led to observations of light from the afterglow of the explosion, finally connecting a gravitational-wave-produ...

SLAC National Accelerator Laboratory: The Advanced LIGO gravitational wave detectors have announced their first observation of a binary neutron star coalescence.

Roscosmos has rescheduled the launch of the Russian Progress 68 cargo spacecraft for Saturday, Oct. 14 at 4:46 am EDT (2:46 p.m. local time in Baikonur). The spacecraft is carrying almost three tons of food, fuel and sup...

About 130 million years ago, in a galaxy far away, two neutron stars collided. The cataclysmic crash produced gravitational waves, ripples in the fabric of space and time. This event is now the 5th observation of gravita...

NASA's Jet Propulsion Laboratory News and Features: NASA's Cassini spacecraft ended its journey on Sept. 15 with an intentional plunge into the atmosphere of Saturn, but analysis continues on the mountain of data the spa...

"This is only a beginning. There are many innovations to come and I don't know where we're going to be in 10 years, 20 years, 30 years," said Peter Michelson, a professor of physics at Stanford University. "The window is...

In the world of astrophysics, Aug. 17, 2017, was a red-letter day. "This is a game-changer for astrophysics," said UC Santa Barbara faculty member Andy Howell, who leads the supernova group at the Las Cumbres Observatory...

The NASA/ESA Hubble Space Telescope has observed for the first time the source of a gravitational wave, created by the merger of two neutron stars....

CAPE CANAVERAL AIR FORCE STATION, FL -- A clandestine black ops satellite supporting US national defense launched into the black skies over Florida's spaceport in the dead of night Sunday, Oct. 15, on a mission for the U...

The astrophysics world is abuzz after the first-ever observation of two neutron stars merging in a cataclysmic crash that left a rich trail of debris for scientists to comb through.

Several observatories captured imagery of the source of the gravitational waves detected on Aug. 17, 2017.

The historic discovery of gravitational waves from neutron star collisions is heralding a new age of gravitational astronomy.

ESO's fleet of telescopes in Chile have detected the first visible counterpart to a gravitational wave source. These historic observations suggest that this unique object is the result of the merger of two neutron stars....

No one knows for sure what a long-range space journey will be like for the people on board. Nobody in the history of our species has ever had to deal with the "Earth-out-of-view" phenomenon, for instance.

More than a month before a game-changing detection of a short gamma-ray burst - a finding announced today - scientists at Oregon State University predicted such a discovery would occur.

When a pair of superdense neutron stars collided and potentially formed a black hole in a galaxy 130 million light-years from Earth, they unleashed not only a train of gravitational waves....

"We haven't altered the laws of physics," says Mikael Afzelius, a member of the applied physics group at the University of Geneva. "What has changed is how we handle the flow of data." Quantum theory predicts that a vast...
