The newly identified black hole is located about 2,000 light-years from Earth – relatively close in cosmic terms
An artist's impression shows the orbits of the most massive stellar black hole in our galaxy, dubbed Gaia BH3, and a companion star, in this handout image obtained by Reuters on April 16.Astronomers have discovered a black hole with a mass about 33 times greater than that of our sun, the biggest one known in the Milky Way aside from the supermassive black hole lurking at the centre of our galaxy.
“This black hole is not only very massive, it is also very peculiar in many aspects. It is really something we never expected to see,” said Pasquale Panuzzo, a research engineer at the French research agency CNRS working at the Observatoire de Paris and lead author of the study published in the journal Astronomy & Astrophysics.
Black holes that result from the collapse of a single star are called stellar black holes. Gaia BH3 is the largest-known stellar black hole, according to astronomer and study co-author Tsevi Mazeh of the Tel Aviv University in Israel. When that star exploded at the end of its lifespan – called a supernova – it blasted some material into space while the remnant violently collapsed to form a black hole.
