The "neighbor" Nebula outside the galaxy was found a rare dormant black hole

Recently, a team of international experts famous for exploring black holes in the world found a dormant star quality black hole in Dagelun Nebula. Magellan Nebula is a galaxy near the galaxy. The team is Kareem El-Badry from the Celestial Physics Center, which is called "Black Hole Destroyer" by other astronomers.

They also found that the stars with black holes disappeared and there were no traces of large -scale explosions. The team claimed that this was the first "dormant" star quality black hole that was clearly detected outside the Milky Way. The quality of the newly discovered black hole was at least 9 times that of our sun and around a hot blue of 25 times the quality of our sun. Star running.

When large stars are close to their life span and collapse under their own gravity, there will be a black hole with star quality. In a system rotating from two stars, the so -called double star, this process will leave a black hole and a glowing companion running on the track. If a black hole does not emit a high -level X -ray radiation, it is "dormant", which is usually the way to detect this black hole.

The reason why dormant black holes can attract strong attention from scientists is that there are very few dormant black holes and the environment, so it is really difficult to observe. The discovery of dormant black holes also gave the research team a unique view of the process of formation of black holes.
