LIGO gravitational wave detections. All-sky map of gravitational wave signals detected by LIGO beginning in 2015 (GW150914, LVT151012, GW151226, GW170104), and, more recently, by the LIGO-Virgo network (GW170814, GW170817). After Virgo came online in August 2017, scientists were better able to localize the gravitational-wave signals. The background is an optical image of the Milky Way. The localizations of GW150914, LVT151012, and GW170104 wrap around the celestial sphere, so the sky map is shown with a translucent dome. LIGO (Laser Interferometer Gravitational-Wave Observatory) consists of two sites in the USA. The Virgo interferometer is located in Italy. Such signals are typically due to the merger of black holes or neutron stars. Image published in 2017.
