LIGO and Virgo Detect Neutron Star Smash-Ups

News Release • May 2, 2019

LIGO and VIrgo detect gravitational waves from what appears likely to be a crash between two neutron stars, and possibly a neutron star-black hole collision.
LIGO and Virgo Announce Four New Gravitational-Wave Detections

News Release • December 3, 2018

The National Science Foundation's LIGO (Laser Interferometer Gravitational-Wave Observatory) and the European-based VIRGO gravitational-wave detector have published new results from the first two Observing runs. Four new black hole mergers are newly announced, The LIGO and Virgo collaborations have now confidently detected gravitational waves from a total of 10 stellar-mass binary black hole mergers and one merger of neutron stars, which are the dense, spherical remains of stellar explosions.
LIGO and Virgo make first detection of gravitational waves produced by colliding neutron stars

Press release • October 16, 2017

For the first time, scientists have directly detected gravitational waves — ripples in space and time — in addition to light from the spectacular collision of two neutron stars. This marks the first time that a cosmic event has been viewed in both gravitational waves and light.

Detection Portal • February 11, 2016

On September 14, 2015 at 5:51 a.m. Eastern Daylight Time (09:51 UTC), the twin Laser Interferometer Gravitational-wave Observatory (LIGO) detectors, located in Livingston, Louisiana, and Hanford, Washington, USA both measured ripples in the fabric of spacetime – gravitational waves – arriving at the Earth from a cataclysmic event in the distant universe. The new Advanced LIGO detectors had just been brought into operation for their first observing run when the very clear and strong signal was captured.
