Astronomers have discovered a supermassive black hole about 40 billion times the mass of the sun at the center of a bright Abell 85 cluster about 700 million light-years from Earth, according tomedia CNET. On Tuesday, the team of the Max Planck Institute of Extraterrestrial Physics and the University of Munich Observatory published their discovery and analysis of the unusual “monster” black hole in The Astrophysics Journal.
“The direct mass measurements of supermassive black holes are only a few dozen times, and no attempt has ever been made at such a distance,” Jens Thomas, lead scientist on the study, said in a statement. But we already know the size of black holes in this particular galaxy, so we decided to try. “
But how big is the mass of the 40 billion suns? The mass of the sun is an absolute unit, about 1.9891 x 103 kg, and the mass of the sun is 330,000 times the mass of the Earth. In November, when scientists discovered a black hole about 70 times the mass of the sun, it was said to be well above the upper limit of the theoretical prediction. But the newly measured black hole is 40 billion times larger than our sun.
The researchers say the discovery could change the way astronomers estimate the mass of black holes in more distant galaxies, because it is not possible to directly measure the motion of stars close enough to black holes.
