This type of black holes is formed when a star collapses on itself.

A team of scientists led by China have discovered the biggest stellar-mass black hole, which is said to be the equivalent mass of 70 suns. The star orbited the black hole every 79 days, the researchers reported.

The study suggests some potential explanations, including the "exciting possibility" that LB-1 might actually consist of two black holes orbiting each other, though Bregman said that would be rare.

LIU JIfeng said that such black holes should not exist in the Milky Way galaxy as per the current models that handle stellar evolution, and added that the discovery came as an unexpected surprise.

"Now theorists will have to take up the challenge of explaining its formation", he said in a statement. Scientists are now scratching their heads on how LB-1 got so big.

The Chinese team has proposed a number of theories. In this research, LB-1 is twice the size of any black hole found in the Milky Way. While successful, this process limited scientists' ability to find more black holes because the vast majority of them in our galaxy are not actively consuming other stars.

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. David Reitze of the University of Florida, who is the director of the Laser Interferometer Gravitational-Wave Observatory.

"This result so remarkable that the LIGO-Virgo binary black hole collisions detections during the past four years really testifies to a renaissance in our understanding of astrophysical black hole", said Reitze.

Black holes are as mysterious as they can.

"Black holes of such mass should not even exist in our Galaxy, according to most of the current models of stellar evolution", said Prof. In this context, the very mass of LB-1 is theoretically impossible unless new theories are proven. 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.

A black hole with a mass 70 times greater than the Sun was discovered, leaving scientists stunned.

It is believed that stellar black holes are commonly dispersed throughout the universe, but they are hard to detect because they normally do not emit X-rays, they only do so when they engulf gas from a star that has ventured close enough. Because stellar black holes are so hard to identify, about two dozen of them were measured.

The researchers on the Chinese language Academy of Sciences tried a assorted capacity. There are lots of sorts of black holes, and stellar black holes luxuriate in LB-1 are on the smaller aspect, in response to NASA.

But LAMOST, constructed between 2001 and 2008 in north China's Hebei province, allows researchers to detect up to 4,000 stars simultaneously with each exposure, making it one of the world's most powerful ground-based telescopes.
