Light detected with gravitational waves for the first time
In a first, scientists have detected light tied to a gravitational-wave event, due to two merging neutron stars (superdense fuel-exhausted stars) in a galaxy 130 million light-years away. The ripples in spacetime were accompanied by high-energy gamma-ray bursts, detected by NASA's telescopes. Previous four gravitational-wave detections resulted from black hole collisions, without light emission.
