“It took less than a second for the space observatory hidden in Louisiana woods to detect the most massive black hole ever observed. Only one tenth of a second to be exact. That’s how long it took for the Laser Interferometer Gravitational-Wave Observatory in Livingston to detect the collision of two massive black holes creating a binary black hole with the largest mass observed in space. … The merging of the two black holes well beyond the Milky Way galaxy created a black hole that is approximately 225 times the mass of the sun, according to LIGO. This mass puts it in a rare category of black holes called intermediate-mass black holes. The most massive black hole merger previously detected in 2021 had a total mass of 140 times of the sun.” (07/15/25)
