Space telescopes observed a short gamma-ray burst, a powerful beam of radiation, coming from about the same part of the sky about two seconds later.

"The gathering will begin with an overview of new findings from LIGO, Virgo and partners that span the globe, followed by details from telescopes that work with the LIGO and Virgo collaborations ...

For the first time ever, researchers have recorded the cataclysmic smash-up of two neutron stars by virtue of their gravitational waves as well as their electromagnetic emissions, producing ...

For the first time, scientists have seen the source of gravitational waves from two colliding neutron stars, and the space oddity doesn't stop there. On Aug. 17, 2017, the gravitational-wave ...
