Medium-sized black hole seen lurking in the Milky Way

The cloud, named CO-0.40-0.22, was intriguing because not only did it represent the possibility of finding an intermediate black hole, but it could also explain how massive black holes come to exist at the centers of galaxies, such as our own Milky way. The discovered cloud is the second IMBH candidate within the Milky Way and the second largest after Sagittarius A.

"We know that smaller black holes form when some stars die, which makes them fairly common", she said.

Theoretical studies have predicted 100 million to one billion black holes should exist in the Milky Way - but only 60 or so have been identified through observations so far.

That's how the black holes get massive so quickly.

This is the first hint that a black hole could be present, as scientists are unable to see black holes, which do not emit light.

A recent research stated that the black holes are important for the creation of galaxies, stars and life itself.

In this case, the presence of the black hole was given away by the unusually fast-moving gases surrounding it. Astronomers in Japan observed that the elements wafting around this particular cloud formation, which is a huge gas behemoth 150 trillion kms. wide and is located about 200 light years from the heart of the Milky Way, were moving way quicker and at totally different speeds that those in similar clouds elsewhere in space.

Intermediate-mass black holes (IMBHs) are called the "missing link" that could explain how supermassive black holes are created, Newsweek reports.

"This is the first detection of an intermediate-mass black hole candidate in the Milky Way galaxy", Oka told The Guardian. But researchers are divided over whether these are really midsized black holes, shining bright as they imbibe lots of surrounding gas, or smaller ones ingesting at a superfast rate. A odd molecular cloud was detected in the center of the Milky Way.

If this new black hole is indeed fated to be pulled towards Sagittarius A*, then it will likely be followed by other smaller black holes, in turn becoming mid-sized black holes, in turned consumed by the vast, growing void at the heart of our galaxy.

'Based on the careful analysis of gas kinematics we concluded a compact object with a mass of about 100,000 solar masses is lurking in this cloud'. While the existence of such a black hole in our galaxy has nearly been settled, not the same can be said for other types of black holes. With an estimated mass of around 100,000 times that of our sun, they believe it could be a special type of black hole that has always been hypothesized but never officially identified. Scientists have found evidence for star-sized black holes - about ten times the sun's mass-and supermassive ones, which contain millions or even billions of solar masses, in galactic cores.

Intermediate-mass black holes (IMBHs) have always been the talk of scientists and were believed to have been the missing factor in explaining how the super massive black holes are formed.
