Until recently, stellar black holes could be seen only when they gobbled up gas from a companion star, creating powerful X-ray emissions detectable from Earth.
Scientists have discovered a massive black hole that "shouldn't even exist" and it's not the one in your wallet as the Christmas season rolls on.
Previously, scientists believed that the stars in our galaxy will lose much of their mass in the final stages of their life before it becomes a black hole, Jifeng said in the release. Scientists generally accept that black holes in our Galaxy could be no more than 20 times the mass of the Sun. They are the remnants of stars that have died and usually have a mass of 10 to 24, the sun, NASA said. Liu's team, however, sought out stars that are orbiting inactive black holes, which are apparent only by their gravitational pull. "Now theorists will have to take up the challenge of explaining its formation". A Chinese-led workforce found a stellar-mass black hole that seems to be 68 instances heftier than Earth's sun - practically 3 times larger than the heaviest such objects ought to be, based on present considering.
But because the vast majority of black holes are not that hungry and don't emit revealing X-rays, only about two dozen spacetime regions have been identified and measured.
After the initial discovery, the world's largest optical telescopes - Spain's 10.4-m Gran Telescopio Canarias and the 10-m Keck I telescope in the United States - were used to determine the system's physical parameters.
That mentioned the Chinese-led staff was famous that, if LB-1 had been nearer, it could be much less luminous and fewer large - and its noticed temperature can't be defined with much less luminosity.
The discovery of the black hole also ties in with another recent astrophysics discovery - the detection of ripples in space-time caused by black hole collisions in distant galaxies. For example, the mass of the black hole depends on its calculated distance. The other theory that has been considered is that the black hole was created from a "fallback supernova".
Liu's team discovered the black hole using gravitational observations from China's Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST).
Liu said the research team aims to utilize the LAMOST to discover almost 100 black holes within the Milky Way in the coming five years.
A paper on the discovery of the black hole has been published in the journal Nature.
"This remarkable result", Reitze, a professor at the University of Florida, added, "really points toward a renaissance in our understanding of black hole astrophysics".
