Scientists discover 'monster' black hole so big it shouldn't exist

Now, an worldwide team may have found one that is so massive it actually breaks the scale! If that is true, the black hole could be exclusively 10 instances the mass of the solar.

There are "supermassive black holes", one of which is thought to reside in the core of every galaxy we can see, including our own Milky Way. Additionally, the discrepancy with Gaia's information could possibly be defined if the star has been excessively wobbling across the black hole, Science News famous. Until now, scientists had estimated the mass of an individual stellar black hole in our galaxy at no more than 20 times that of the Sun.

"LB-1's large mass falls into a range "known as the "pair instability gap" where supernovae should not have produced it", Reitze said". In some of the distant galaxies, the black holes with 70-80 solar masses have noticed from 2015.

Scientists are uncertain as to how this hole came about but theories have been put forward. According to Jifeng Liu, scientist of National Astronomical Observatory, such a massive black hole should not exist.

Its mass is 70 times larger than the sun, according to the Chinese Academy of Sciences.

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. [Image: ESO/L. Calçada] Because they could not identify the star's mate, that indicated to that body being a quiet black hole that was not generating X-rays as it absorbed matter from its accretion disk.

After earning her wings two days before the Navy Day on Wednesday, Shivangi said she was happy with her achievement. Shivangi was commissioned into the Indian Navy past year after initial training.

To circumvent this problem, Liu & Co. used China's Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) for a needle-in-a-haystack search for stars orbiting an invisible object pulled by its gravity. By their calculations, however this unseen black hole companion was huge, weighing in at almost 70 solar masses!

How far away is it?

"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", Liu explained. A light-year is defined as the distance light travels in one year, which is around 6 trillion miles.

What's more, the large black hole can also be comparatively near Earth in cosmic phrases. Would a companion star have survived the titanic forces in play around such an event, or in its aftermath?

The discovery of LB-1 fits nicely with another breakthrough in astrophysics. Or, is there some other explanation for how this huge black hole can exist?

The newly discovered black hole has become one of the topics of interest in the Milky Way and researchers are expected to carry on a series of follow-up observations to understand it. LIGO director David Reitze said the latest discovery has forced us to re-examine our models which describe the formation of black holes.
