A huge black hole has been brought to light on the other side of the galaxy. It is so massive, and according to scientists, it should not even be possible. In a study that got published on Wednesday in the journal Nature, Chinese astronomers detail their discovery of the black hole, dubbed LB-1, in the Milky Way with a mass of approximately 70 times that of the sun. Formerly, scientists believed that they could only be 20 times the weight of the sun. From the Chinese Academy of Sciences, a research team used the Large Sky Area Multi-Object Fiber Spectroscopic Telescope to look for signs of LB-1. By using LAMOST, the researcher team found stars moving across the sky, seemingly orbiting a hidden object. Follow-up observations with telescopes in Spain and the U.S. led to the discovery of a star about eight times larger than the sun, which is orbiting the black hole in every 79 days.
According to the press release, such a search is like finding out the proverbial needle in a haystack, as only one may be circling the black hole in a thousand years. According to most of the present models of a stellar vent, black holes of such mass should not exist in our galaxy, said Lifeng Liu, who is the lead researcher professor. He also added that they thought that very massive stars with the chemical opus typical of our galaxy must apply most of their gas in powerful stellar winds, as they refuge the end of their life. Therefore they should not leave such a massive leftover.
Some stellar black holes are detectable when they devour gas from a companion star, and this causes them to discharge powerful X-ray emissions, but this illusion is something of a rare happening. Stellar black holes are hard to identify, and only one or two of them have been measured. Astronomers estimate that the Milky Way galaxy could be loaded up with 100 million black holes.
