Fifty Gravitational Wave Events Illustrated
Over fifty gravitational wave events have now been detected, mostly in 2019 by LIGO and VIRGO. These events are the distant, violent collisions of black holes, neutron stars, or both. The featured illustration summarizes the masses of these events. Blue dots indicate higher-mass black holes, while orange dots denote lower-mass neutron stars.
