Gravitational Wave GW170814 Hits Earth

Science 2.0 - Sep 28 2017 - 18:09

Three detectors tracking gravitational waves emitted by a merger of two black holes have brought science a little closer to locating a gravitational wave's birthplace in space. 

Gravitational waves are ripples in space and time created when two massive, compact objects such as black holes merge. The new detections were made on August 14, 2017 by two gravitational-wave detectors in the United States - Hanford and Livingston at the Laser Interferometer Gravitational-Wave Observatory (LIGO), operated by Caltech and MIT - and by the Virgo Gravitational-Wave Observatory in Italy.
