Overseas Network, July 19th. According to the British "Guardian" reported on the 18th, scientists found dormant black holes outside the galaxy for the first time, with 9 times the quality of the sun. Researchers said it was a "exciting discovery".

A researcher at the University of Sheffield, England said this was "the first black hole monitoring outside the galaxy." For more than two years, researchers have been looking for the black hole double -star system and named the black hole dual -star system discovered as VFTS243.

When a large -quality star reaches the end of its life, it has collapsed by its own gravity, and a star -rated black hole is formed. Two stars rotate around each other, and their running track will leave a black hole and a glowing companion. If a black hole does not emit a high -level X -ray radiation, it indicates that it is in a dormant state. Dormant black holes are difficult to find because they rarely interact with the surrounding environment.

According to reports, the newly discovered dormant black holes are at least 9 times the quality of the sun, which runs around a hot blue star with a mass of 25 times the sun. Researchers have found that the stars in the black hole dual -star system have disappeared without any signs of the supernova explosion. Shonar, a researcher at the University of Amsterdam in the Netherlands, believes that stars have not exploded when collapsed, which "has a huge impact on exploring the origin of the merger of black holes."
