Discovery of record-breaking black hole collision surprises astronomers – CBC

A team of international astronomers has caught the merger of two black holes of unprecedented masses creating yet another massive black hole — one that astronomers believed existed in theory but that had never been detected.

The two caught in the act were roughly 85 times and 66 times the mass of the sun (measured as solar masses). After the pair merged — producing a gravitational wave picked up by detectors — they created a black hole 142 times the mass of the sun.
