Finding GW170817 In The Sky

On October 16, 2017, the LIGO Scientific Collaboration, Virgo Collaboration, and its partners announced the first observation of gravitational-waves from a pair of inspiraling neutron stars.

Electromagnetic emission from the resulting collision was also observed in multiple wavelength bands. This occured on August 17, 2017 and represents the first time a cosmic event was observed with both gravitational waves and light.
