Gravitational-wave source · GWTC-4.1
A black hole of about 14 solar masses, formed on 2023-06-27 when two black holes of roughly 8 and 6 solar masses spiralled together 995 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 8 (7–10) and 6 (5–7) solar masses. The remnant is 14 (13–14) 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 40 km in radius. The waves we detected had been travelling for 995 million years before they reached us.
