The LIGO-Virgo-KAGRA international network of Gravitational Wave observatories announced the discovery of an exceptional astronomical event. The event is named GW230529, as it was detected during the first week of the current observing run on May 29 2023 by the LIGO Livingston Observatory in the U.S. The signal resulted from the collision between a neutron star and another compact object of undetermined nature, which lies in the "mass-gap" between the heaviest known neutron stars and the lightest black holes.
