We already know that a supermassive black hole lies in the center of the Milky Way, playing a major role in the existence of the galaxy itself. But the galaxy could be loaded with other black holes, even f it’s pretty hard to spot one. Scientists have recently found another one, and it’s outrageously big.
LB-1 is the newest huge black hole spotted in our galaxy, and it’s 70 times more massive than our Sun. It’s located 15,000 light-years from Earth.
It challenges existing models of how stars evolve
The newly discovered black hole is so big that it challenges the way scientists believe that stars are evolving over time. There are basically two types of stellar black holes: the more common ones are up to 20 times more massive than the Sun, while the supermassive black holes are at least one million times bigger than our star.
Liu Jifeng led the research, and he’s a professor at National Astronomical Observatory of China. He stated loud and clear:
Black holes of such mass should not even exist in our galaxy, according to most of the current models of stellar evolution,
Now theorists will have to take up the challenge of explaining its formation
The origin of supermassive black holes is also uncertain. But the difference between such objects and LB-1 is that in the first case scientists have provided some theories.
By definition, a black hole is the ultimate fate of a star. After losing all the hydrogen that converts into helium, a star transforms into a supernova, a tremendous explosion of energy that could be as big and bright as an entire galaxy. The core remains, which is called a neutron star. After a while, the neutron star also collapses in itself, forming a black hole.
The discovery of the huge black hole LB-1 has been published in the journal Nature.
