Scientists derive 'monster' black hole so mountainous it must no longer exist

According to Liu Jifeng, a National Astronomical Observatory of China professor who led the research, "Black holes of such mass should not even exist in our galaxy, according to most of the current models of stellar evolution".

After finding the star, which they named LB-1, the researchers used two huge optical telescopes - the Gran Telescopio Canarias in La Palma, Spain, and the Keck I telescope in Hawaii - to determine the mass of the star and its black hole companion. This is because when the stars explode and die, they lose a lot of their mass which is swept away by the winds.

Chinese scientists have discovered a stellar black hole that's so large it shouldn't exist based on current theories of black-hole formation.

"This discovery forces us to re-examine our models of how stellar-mass black holes form", Reitze added.

The LB-1 black hole shouldn't be confused with the supermassive black holes, which are much bigger - probably billions times the mass of our sun.

Researchers revealed that the newly discovered black hole has a mass 70 times greater than the mass of the sun. The chemical composition of our system's most enormous stars proposes that they lose the greater part of their mass toward the finish of their lives through blasts and wonderful excellent breezes, before the star's center crumples into a black hole.


Scientists imagine supermassive black holes is probably to be linked to the formation of galaxies, as they in total exist on the guts of the giant monumental name systems - but it completely is tranquil undecided exactly how, or which receive first. "Recently, the Laser Interferometer Gravitational-Wave Observatory (LIGO) and Virgo gravitational-wave detectors have begun to catch ripples in space-time caused by collisions of black holes in distant galaxies". Previously, scientists thought they could be about 20 times the mass of the sun. The mere existence of LB-1 has puzzled scientists, who are not forced to rethink theories about its formation.

The black hole in question was spotted in galaxy Messier 87 (M87) that is 55 million light-years away.

LB-1 was discovered by an global team of scientists using China's sophisticated LAMOST telescope.

"That means that this is a new kinda black hole, formed by another physical mechanism!"

Jifeng's researchers zeroed in on LB-1 with China's Large Sky Area Multi-Object Fiber Spectroscopic Telescope, which looks for the "one out of a thousand stars" orbiting an invisible object's gravitational pull. They're so elusive that scientists occupy handiest stumbled on, known, and measured about two dozen stellar black holes, the press release said.

The black hole, which is the subject of a new research paper published in Nature, left the research team scratching their heads.
