NGC 4993 (also catalogued as NGC 4994) is an elliptical galaxy in the constellation Hydra, discovered in 1789 by Wilhelm Herschel.[2] In August 2017, astronomers reported[3] that the short gamma-ray burst GRB 170817A, of the sort conjectured to be emitted in the collision of two neutron stars,[4] was detected in this galaxy.

On 16 October 2017, the team officially announced the detection of a gravitational wave, named GW170817, associated with the merger of two neutron stars.[5][6][7] A gravitational wave event associated with this burst provided direct confirmation that binary neutron star collisions produce short gamma-ray bursts.[8]
