The Advanced Laser Interferometer Gravitational-wave Observatory (LIGO) is a facility dedicated to detecting ripples in the spacetime continuum, known as gravitational waves. Gravitational wave astronomy is a new field. The LIGO facility has been used for two observation campaigns so far. The first one ran from 12 September 2015 to 19 January 2016. During this time, three black hole collisions were detected. The second observation run lasted from 30 November 2016 to 25 August 2017. During this run, the collision of two neutron stars was detected. The visible light signals from the event were also detected by other astronomical instruments, heralding a new era in multimessenger astronomy, where the same event is simultaneously observed by multiple observatories, in different forms of radiation. Three additional black hole mergers were detected during the second run.
