Yes, on August 17, 2017, the LIGO Scientific Collaboration and the Virgo Collaboration detected gravitational waves from the merger of two neutron stars. This historic detection was further supported by a simultaneous gamma-ray burst, designated as GRB 170817A, that was observed from the location of the merger. This marked the first detection of both gravitational waves and gamma rays from a single astronomical event, which provided exceptional insights into the properties and astrophysical processes associated with merging neutron stars.
