Gravitational-wave source · GWTC-2.1-confident
A black hole of about 107 solar masses, formed on 2019-07-06 when two black holes of roughly 74 and 39 solar masses spiralled together 11.8 billion light-years away. LIGO and Virgo felt the collision as ripples in spacetime.

the two that merged
The two black holes that merged were about 74 (57–94) and 39 (24–58) solar masses. The remnant is 107 (91–133) solar masses. Values in parentheses are the 90% credible ranges from LIGO, Virgo and KAGRA (GWTC).
Its event horizon, the edge past which nothing returns, spans about 317 km in radius. The waves we detected had been travelling for 11.8 billion years before they reached us.
