LIGO Detects gravitational waves

The gravitational waves that LIGO detects are caused by some of the most energetic events in the Universe—colliding black holes, merging neutron stars, exploding stars, and possibly even the birth of the Universe itself This energy is emitted as a final strong burst of gravitational waves. It is these gravitational waves that LIGO has observed. The existence of gravitational waves was first demonstrated in the 1970s and 80s by Joseph Taylor, Jr., and colleagues Information about gravitational-wave detections made by LIGO to date. Jump to a separate page for a specific event (listed in reverse-chronological order of announcement date), or see the General Detection Resources section below for further information on LIGO detections That means that while LIGO can detect gravitational waves from merging stellar-mass black holes and possibly neutron stars, they are probably deaf to a thick slice of the gravitational wave.. The Laser Interferometer Gravitational-Wave Observatory (LIGO) is a large-scale physics experiment and observatory designed to detect cosmic gravitational waves and to develop gravitational-wave observations as an astronomical tool
