Chinese astronomers discover unexpected huge stellar black hole — China Focus

Now, an global team may have found one that is so massive it actually breaks the scale! Astronomers didn't found any black hole like this. Astronomers have finally unveiled the first photo of a black hole.

Computations propose that the Milky Way world's outstanding mass dark gaps - which structure after the rough passings of mammoth stars - should top out at just multiple times the mass of the sun, the specialists said. The hole is called LB-1 and is 70 times larger than our sun en masse, which is an wonderful discovery because it was previously thought that black holes could only have a mass of 20 times our sun. Intriguingly, the black holes involved in such collisions are also much bigger than what was previously considered typical. In some of the distant galaxies, the black holes with 70-80 solar masses have noticed from 2015.

Just the other month, scientists found what could be the tiniest stellar black hole ever recorded.

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. Liu Jifeng, says in a statement: "Black holes of such mass should not even exist in our Galaxy, according to most of the current models of stellar evolution".

LB-1 was observed as Liu's team analyzed a massive blue star, approximately 15,000 light-years away, oscillating around in the background of space. Based on this wobble, they found the best explanation was that the star was orbiting some other object, once every 79 days. The team used China's Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) to identify the star. By their calculations, however this unseen black hole companion was huge, weighing in at almost 70 solar masses!

Calculations recommend that the Milky Way galaxy's stellar-mass black holes - which kind after the violent deaths of big stars - ought to prime out at exclusively 25 instances the mass of the solar, the researchers stated.

As per Liu, the most massive stars in our galaxy usually lose a huge quantity of their mass as they reach the end of their lives because of having incredibly powerful stellar winds. "Now theorists will have to take up the challenge of explaining its formation". A light-year is defined as the distance light travels in one year, which is around 6 trillion miles. Dubbed as LB-1, the black hole has given sleepless nights to researchers as they are busy in figuring out how it got so big.

"This discovery forces us to re-examine our models of how stellar-mass black holes form", LIGO Director David Reitze, from the University of Florida said. This discovery along with the LIGO-Virgo detections of binary black holes has pointed towards a new beginning of the understanding of black hole astrophysics.
