The dormant stellar-mass black hole in the Large Magellanic Cloud is the first to be confirmed outside of the Milky Way.
Shenar and his colleagues discovered a stellar-mass black hole that contains about nine times the mass of the sun and is located in the Tarantula Nebula, a star-forming region of a galaxy neighboring ours, the. The black hole orbits a huge blue star with a mass equivalent to 25 suns; the duo make up a binary system that has been named VFTS 243.
"The star that formed the black hole in VFTS 243 appears to have collapsed entirely, with no sign of a previous explosion," Shenar said."Evidence for this 'direct-collapse' scenario has been emerging recently, but our study arguably provides one of the most direct indications. This has enormous implications for the origin of black-hole mergers in the cosmos."
