Gravitational-wave source · GWTC-4.1
A black hole of about 80 solar masses, formed on 2023-06-30 when two black holes of roughly 51 and 33 solar masses spiralled together 17.6 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 51 (36–71) and 33 (20–48) solar masses. The remnant is 80 (62–104) 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 236 km in radius. The waves we detected had been travelling for 17.6 billion years before they reached us.
