740 million light years away is a completely different universe of black holes

This new type of black hole opens up a lot of research potential that people have never thought of.

which is a mysterious concept for us. Despite the decades of research, what is gained about cosmic black holes remains just as salty as the potential for knowledge provided by them.

Based on the limited knowledge of black holes, humans divide it into two types according to size. One is a small hole , with several tens of times the Sun's mass. The other is a supermassive black hole , "heavy" millions, even billions times more than the solar system's fireball.

The sun has a huge mass, but a black hole can be billions of times larger.

Recently, however, it continues to surprise us, as scientists find evidence of a completely different kind of black hole, in the size between two types. They call it a medium-sized black hole , and it's 740 million light-years away.

Specifically, this black hole is located in a very large galaxy. Thanks to X-ray bursts emitted when a black hole swallowed a star, scientists can confirm its existence.

In fact, such explosions often appear in the center of the galaxy, where black supermasses exist. Therefore, finding a large black hole at the edge of the galaxy is truly surprising. And according to calculations, this black hole's mass is about 50,000 times our Sun.

"We found light from a star through two pictures since 2005. This light is greener, and brighter than usual," said Jay Strader, an astronomer from the University of Michigan.

Thanks to the X-ray explosion, scientists discovered mid-range black holes.

"By comparing the data, it seems that this star has been" attacked "around October 2003 by our time, creating energy bursts about 10 years later."

Strader and his colleagues found this evidence in the data provided by XMM-Newton - the missile of the European Space Agency ESA. However, they did not expect to see the final scene of a star, when it was attacked by a medium-sized black hole. And with the existence of this black hole, it is shown that there are many black holes in the same universe.

"Having more new knowledge will help us better understand these black holes, " said Norbert Schartel, project manager XMM-Newton of ESA.
