The discovery of gravitational waves last year sent ripples through the entire field of physics. It also ushered in a new era of astronomy.
Gravitational waves are ripples in space-time created by the interaction of massive objects in space, such as black holes and neutron stars. Their existence was first predicted by Albert Einstein in his 1916 paper describing his theory of general relativity. In 2015, scientists made the first detection of gravitational waves, observing ripples from the collision of two black holes. The discovery won astrophysicists Kip Thorne, Barry Baris and Rainer Weiss the 2017 Nobel Prize for Physics. Subsequent observations have also detected gravitational waves from colliding neutron stars. Learn more about gravitational waves here.
For the first time, astronomers have detected evidence of a cocoon of material blasting out from a pair of merging neutron stars.
A dedicated scientist engaged an audience of college students and local leaders in New York on the emerging field of gravitational wave astronomy.
Astronomers have pinpointed five pairs of merging black holes using three different space and ground-based instruments and two sky surveys.
For the first time ever, scientists around the world detected gravitational waves and light from the collision of a pair of neutron stars. See the epic discovery in pictures here.
The gravitational-wave research community seems to be having a remarkable string of good luck. Here's what the smashing finding means.
For the first time, gravitational waves generated by the merger of two neutron stars have been detected. And that merger was also confirmed optically!
The era of multi-messenger astronomy has officially begun. But what does that phrase mean, and how will it change the study of the cosmos?
Breathtaking images from the explosive merger of two neutron stars were captured by multiple observatories on Earth and in space.
The historic discovery of gravitational waves from neutron star collisions is heralding a new age of gravitational astronomy. Read on to see what exactly was discovered and how it was made.
There's a big gravitational-wave announcement coming later this month, but insiders won't reveal any details. Here are our educated guesses about what the collaboration will reveal.
