Newly discovered black hole is so large, it shouldn't exist

Black holes discovered to actually be bigger than expected, astronomers say

A recent discovery was made regarding the actual size of black holes as scientists found that it is a lot bigger than we generally believe it is. The new Black Hole is located around 15000 light-years away from the Earth.

"Sunless holes of such mass must no longer ever even exist in our galaxy, in response to most of primarily the latest units of stellar evolution", said Liu Jifeng, head of the team that made the discovery.

Bregman said scientists are always trying to learn more about the birth and death of stars, and the discovery of one as large as LB-1 could inform that process. They are the remnants of stars that have died and typically have the mass of 10 to 24 suns, NASA says.

A team of Chinese scientists spotted a black hole that is 70 times larger than the sun.

Now that scientists know how large stellar black holes can become, they're eager to revisit their theories about these cosmic phenomenon and their role in our universe.

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. Earlier, researchers had believed potentially the most mass of a gloomy hole could presumably not exceed 20 times the mass of our sun, but LB-1 defies those beliefs.

"We thought that very massive stars with the chemical composition typical of our Galaxy must shed most of their gas in powerful stellar winds, as they approach the end of their life".

"LIGO/Virgo black holes are naturally explained within the framework of standard stellar evolution theory", added Dr. Chris Belczynski, from the Polish Academy of Sciences. David Reitze of the University of Florida, who is the director of the Laser Interferometer Gravitational-Wave Observatory. Previously, scientists thought they could be about 20 times the mass of the sun. Because stellar black holes are so hard to identify, about two dozen of them were measured.

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. Also, the discrepancy with Gaia's data could be explained if the star were excessively wobbling around the black hole, Science News noted.

The discovery is reported in a paper in the journal Nature.

That said, the Chinese-led team noted that, if LB-1 were closer, it would be less luminous and less massive - and its observed temperature can not be explained with less luminosity. That's how the researchers came across one star 15,000 light-years away that was dancing around nothing - but was held in an orbit by something that could only be a black hole, they wrote. These twin discoveries, the collision, and now LB-1 - indicates that scientists are reaching "a revival in our understanding of black hole astrophysics", Reitze said in the press release.
