Gravitational-wave source · GWTC-5.0
A black hole of about 24 solar masses, formed on 2024-10-11 when two black holes of roughly 20 and 6 solar masses spiralled together 691 million 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 20 (18–22) and 6 (5–7) solar masses. The remnant is 24 (23–27) 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 72 km in radius. The waves we detected had been travelling for 691 million years before they reached us.
