Gravitational-wave source · GWTC-5.0
A black hole of about 88 solar masses, formed on 2024-06-12 when two black holes of roughly 55 and 38 solar masses spiralled together 20.2 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 55 (42–76) and 38 (22–54) solar masses. The remnant is 88 (71–113) 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 260 km in radius. The waves we detected had been travelling for 20.2 billion years before they reached us.
