A super “monster black hole” with 70 times the mass of the sun, scientists exclaim: it shouldn’t exist

Scientists from the Chinese Academy of sciences have made another major discovery in the universe six million light-years away from the earth! With the help of Guo Shoujing telescope, a major national science and technology facility independently developed by China, scientists have discovered one of the most massive stellar black holes known in the universe, which completely refreshes people’s previous understanding of stellar black holes, and also finds a new way to discover black holes for the whole world!


What is a star black hole? As we all know, in the final stage of life evolution, stars will become white dwarfs, neutron stars or black holes due to their own size. Stellar black holes refer to stars whose mass is about three times the mass of the sun. When the internal energy is exhausted, they will collapse into a black hole. According to the mass size, they can be divided into mini black holes, stellar black holes and supermassive black holes.

Prior to that, scientists found the largest stellar black hole in Cassiopeia, which is about 24-33 times the mass of the sun, 1.8 million light-years away from the earth. It is in a binary system and rotates with another late life star. Previously, scientists believed that the black hole, 15.7 times the mass of the sun, discovered in 2007, has become the largest star shaped black hole in the universe. It shows that black holes formed after the death of massive stars are bigger than scientists think.


This time, how did Chinese scientists discover this “Big Mac”? As we all know, black holes, as the products of burning stars, do not emit light, because any matter, including light, can not escape as long as it is attracted by black holes. In the process of phagocytosis, various types of cosmic rays will be released. Scientists use these cosmic rays as the basis to determine the possible location of black holes.


The number of black holes in space is so large that there may be more than 100 million stellar black holes in the galaxy alone. However, due to the limitation of current technology, scientists only found about 20 stellar black holes in the galaxy, and the mass of these black holes is very small.

Back in 2016, Chinese scientists have begun to explore the massive black hole in the universe until they found this “Big Mac”. They have observed more than 3000 stars in total. Finally, in the binary system of X-ray radiation, they found a blue star, which is about eight times the mass of the sun and moves around an invisible celestial body.


Considering that black holes do not emit light, scientists speculate that there is likely to be a huge black hole in the binary system. With the deepening of research, scientists have found more companion stars around the black hole, many of which are 20 times more massive than the sun, which indicates that the mass of this black hole is probably larger than that of all stellar black holes previously discovered.


Finally, through telescope observation, through a series of data analysis, confirmed the spectral properties, calculated the mass of the black hole, which is about 70 times that of the sun. According to scientists, the discovery of this massive stellar black hole completely overturns the previous understanding, because according to the previous stellar evolution calculation, the largest stellar black hole is only 25 times the mass of the sun. This black hole has opened a new door for scientists. With the progress of science and technology, it will open a new era of exploring cosmic black holes. Let’s have a look Wait!
