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

The Chinese researchers said in the journal Nature that LB-1 was discovered by monitoring stars that appeared to be orbiting unseen objects. "This is the first".

A black hole can usually be formed in a matter of seconds after a star collapses in on itself.

This is because they believed that stars start to lose their gas as they die, and lose mass as a result.

The newly discovered stellar black hole, called LB-1, has a mass 70 times that of our sun, China's Academy of Sciences said in a statement.

"Black holes of this mass should not exist in our galaxy, according to most current models of stellar evolution", said lead researcher Professor Jifeng Liu.

'Now theorists will have to take up the challenge of explaining its formation'. They're so elusive that scientists occupy handiest stumbled on, known, and measured about two dozen stellar black holes, the press release said. The research team led by Prof LIU Jifeng of the National Astronomical Observatory of China of the Chinese Academy of Sciences (NAOC) discovered this giant black hole at around 15,000 light-years away from the earth.

The Laser Interferometer Gravitational-Wave Observatory at Caltech, overseen by Reitze, had previously detected ripples in spacetime that suggested the possibility of black holes in distant galaxies that were much bigger than what was thought possible. The results, according to the news release, were "nothing short of fantastic".

What's more, the huge black hole is also relatively close to Earth in cosmic terms.

There are additionally supermassive sunless holes, which almost continuously are living within the middle of galaxies and differ from a million to just a few billion occasions the mass of the solar.

"Black holes of such mass should not even exist in our Galaxy, according to most of the current models of stellar evolution".

Astronomers are still only beginning to grasp "the abundance of black holes and the mechanisms by which they form", David Reitze, a physicist at the California Institute of Technology (Caltech) who was not involved in the discovery, told AFP. The scientists discovered LB-1 with the use of their LAMOST optical telescope in order to look for the stars that orbit around an invisible entity and is under the gravitational pull.

"Is that this object extremely weird? Or is it more common than we thought?" Bregman acknowledged. "If we glimpse at 20 [black holes] and safe two of three of those gadgets, that may per chance well successfully be in fact improbable. It would change ideas of how massive stars evolve and die".

Scientists have discovered a "monster black hole" so massive that, in theory, it shouldn't exist. Right here's when a supernova - the closing stage of an exploding monumental name - ejects cloth at some stage within the explosion, which then falls abet into the supernova, making a black hole.
