A collision that occurred between two neutron stars in a galaxy 138 million light years from Earth was observed in August of 2017, generating both gravitational waves that were detected by the LIGO and Virgo gravity-wave observatories, and a gamma-ray burst that was recorded by the Fermi and INTEGRAL satellites. This is the first time that both gravity and electromagnetic waves have been detected from an astronomical event, as all previous detections of gravity waves have come from collisions between black holes.read more
