Massive Black Hole Identified in the Milky Way Galaxy

Recent research involves quite unexpecting discovery. Astronomers have identified a giant black hole in the Milky Way Galaxy that questions existing variants of how stars develop. LB-1 is positioned at 15,000 light-years from our planet and possesses a structure 70 times bigger than the Sun, according to the journal Nature. Milky Way, on the other hand, has approximately a composition of 100 million stellar black holes, but LB-1 is twice as large as anything scientists considered possible.

Liu Jifeng, professor at the National Astronomical Observatory of China, is the one who led the research and explained the importance of the discovery. He detailed: “Black holes of such mass should not even exist in our galaxy, according to most of the current models of stellar evolution.”

Astronomers spotted a massive black hole in the Milky Way, which shouldn’t exist

There are two categories of black holes, according to scientists. The stellar black holes are up to 20 times more larger than the Sun and appear when the center of a vast star falls in on itself. Stellar black holes are usually created in the result of supernova crashes, a phenomenon that occurs when more giant stars burn out at the edge of their lives. The other type, known as supermassive black holes, which are approximately a million more extensive than the Sun, and it is unknown how they formed.

Researchers, however, thought that regular stars in the Milky Way emitted most of their gas within stellar winds, stopping the appearance of a black hole the dimension of LB-1. David Reitze, a physicist at the California Institute of Technology, said, “LB-1’s large mass falls into a range ‘known as the pair-instability gap’ where supernovae should not have produced it. Also, he added: “That means that this is a new kind of black hole, formed by another physical mechanism!”
