A new black hole close to Earth has been discovered that is accompanied by two stars
An artist's impression depicts the orbits of the two stars and the black hole in the HR 6819 triple system, made up of an inner binary with one star and a newly discovered black hole , as well as a third star in a wider orbit , in this image released on May 6, 2020.
"Just around the corner" in cosmic terms, said Chile-based European Southern Observatory astronomer Thomas Rivinius, lead author of the study published in the journal Astronomy & Astrophysics.Black holes are extraordinarily dense objects possessing gravitational pulls so powerful that not even light can escape. Some are monstrous like the one at our galaxy's center 26,000 light years from Earth that is four million times the sun's mass.
Only a few dozen stellar-mass black holes previously were known. But there may be hundreds of millions or even a billion of them in the Milky Way, said astrophysicist and study co-author Petr Hadrava of the Academy of Sciences of the Czech Republic.
