Massive supernova explosion may have created a binary black hole

The supernova SN 2022esa as seen by the Subaru telescope. Was this a precursor to a binary black holes.

Astronomers have observed a strange but powerful supernova explosion that not only marked the death of a massive, highly evolved star, but also may have heralded the birth of a pair of binary black holes.

The team behind this discovery studied the supernova explosion SN 2022esa with the 8.2-meter Subaru telescope located at the Mauna Kea Observatory in Hawaii and the Seimei telescope in Japan.
