The LIGO/Virgo collaboration announced the discovery of a neutron-star
neutron star merger detected in gravitational waves. It ws
subsequently detected across the electromagnetic spectrum by
astronomers around the world.
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.

Observations were made using the Swift satellite (UV), Gemini-South Telescope (infrared) and the Very Large Array (radio).
