Observing neutron stars collide
 
04:18
Astronomers have made one of the biggest breakthroughs of the decade after detecting both gravitational waves and gamma rays from the merger of two neutron stars. On 17 August 2017, the Laser Interferometer Gravitational-wave Observatory (LIGO) and Virgo detected, for the first time, gravitational waves from the collision of a pair of neutron stars. The event was not only “heard” in gravitational waves but also seen in light by dozens of telescopes on the ground and in space. Learn more about what this rare astronomy event taught us in a new video from LIGO and Virgo. (Courtesy: LIGO-Virgo) Read more about the breakthrough here: http://physicsworld.com/cws/article/news/2017/oct/16/spectacular-collision-of-two-neutron-stars-observed-for-first-time
