On August 17, 2017 the Laser Interferometer Gravitational-Wave Observatory (LIGO) detected the merger of two neutron stars. Only 2s later the Fermi Gamma-ray satellite detected a burst of gamma-rays coming from the same direction on the sky. Within a day a new optical source had been detected in the galaxy NGC 4993, about 130 million light years away. It has subsequently been seen by ultraviolet, radio, infrared, and X-ray telescopes on all 7 continents and in space. This continues to be a fascinating event.
