For the first time, three detectors have tracked the gravitational waves emitted by a merger of two black holes–a critical new capability that allows scientists to more closely locate a gravitational wave’s birthplace in space. It is the fourth announced detection of a binary black-hole system by the LIGO detectors and the first significant gravitational-wave signal recorded by the Virgo detector.
