Scientists discover LB-1, a black hole they didn't believe could exist

Chinese scientists discovered a black hole so that's so big that it throws into question previous beliefs about how black holes are formed.

These twin discoveries - the collision, and now LB-1 - existing that scientists are reaching "a renaissance in our working out of black hole astrophysics", said Reitze within the press release.

The stellar gloomy hole, LB-1, became as soon as found by Chinese language astronomers and is speculated to absorb a mass 70 times better than our sun, in accordance with an announcement from the Chinese language Academy of Sciences.

The researchers explained that until a few years ago, stellar black holes could only be discovered when they gobbled up gas from a companion star. It's so massive; it shouldn't exist at all as it challenges the existing models of how stars evolve.

The statement noted that scientists had previously believed that an individual stellar black hole - formed when a star collapses - in our galaxy could weigh only as much as 20 times the mass of our sun.

"In contrast, the LB-1 black hole seems impossible to explain as stars massive enough to form a 68-solar-mass black hole monster should be totally destroyed by powerful pair-instability supernova explosions that leave only scattered gas and dust behind, and not black holes".

"This discovery forces us to re-examine our models of how stellar-mass black holes form", said LIGO Director Professor David Reitze from University of Florida in the US.

Breaking all the understanding of black holes in Milky Way, a team of Chinese researchers has now discovered a huge black hole with a mass 70 times greater than the sun.

Supermassive black holes get all the attention, but an Ohio State University-led team may have found a new type that could lead to an entirely new class of black holes. They discovered a star called LB-1, which is eight times the mass of the sun and that appears to orbit a black hole every 79 days, even though the black hole isn't visible. The ripples have been identified by the Laser Interferometer Gravitational-Wave Observatory (LIGO) in the US and the Virgo gravitational wave detector in Italy. However, the scientists have been capable of identifying only around 20 to 25 of them so far. But, there is a limit that a black hole can have.

Liu and his team made the finding with China's Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST).

The Chinese researchers said in the journal Nature that LB-1 was discovered by monitoring stars that appeared to be orbiting unseen objects. However, the LB-1 is truly of an unprecedented size ever. Because stellar black holes are so hard to identify, about two dozen of them were measured.

The findings were published November 27 in the journal Nature.
