black hole 100000 times massive than Sun

What is Black Hole

A black hole is an area in space where the gravitational force is so strong that light can not escape. Strong gravity arises because the matter was pressed into a tiny space. This contraction can occur at the end of the star’s life. Some black holes are the result of the death of stars.

Because of the absence of light, black holes are invisible. However, space telescopes with special tools can help to find black holes. They can observe the behavior of material and stars that are very close to black holes.

How big are black holes?

Black holes can have different sizes, but there are three main types of black holes. The mass and size of a black hole determine what it is.

The smallest of them are known as primary black holes. Scientists believe that this type of black hole is as small as that of one atom, but with a mass of a large mountain.

The most common type of medium-sized black holes is called “star”. The mass of a starry black hole can be 20 times the mass of the Sun and can enter a ball with a diameter of about 10 miles. Dozens of black holes of the stellar mass can exist in the Milky Way galaxy.

The biggest black holes are called “supermassive”. These black holes have a mass of more than 1 million solar beams in combination and are placed inside a ball with a diameter near the solar system. Scientific evidence suggests that each large galaxy contains a supermassive black hole in its center. A supermassive black hole in the center of the Milky Way galaxy is called Sagittarius A. It has a mass of about 4 million suns and will be placed inside a ball with a diameter near the Sun.

Scientists believe that they discovered a huge black hole near the center of the Milky Way, hiding in a massive cloud of molecular gas. With an estimated mass of about 100,000 times greater than our sun, they believe that it can be a special type of black hole, which has long been put forward, but is not officially identified.

Intermediate black holes (IMBH) are considered the missing link in the evolution of space objects and can help explain how super-massive black holes form. However, there is no direct evidence that IMBH was never found.

In a study published in Nature Astronomy, scientists led by Tomoharu Oki from Keio University in Japan announced a new candidate for IMBH. They discovered a “peculiar” molecular cloud sitting near the center of the Milky Way, which showed some unusual properties that were not visible in similar structures – properties that could be explained by the “gravitational impact” caused by “an invisible compact object with a mass of about 105 solar masses “.

Using numerical modeling of a hidden object, they interpret it as IMBH, which at the present time does not accrete matter – the accumulation of particles by gravitational attraction of more matter. If this is a black hole, it will be the second largest in the Milky Way after Sagittarius A. This is also the second candidate from the IMBH in the Milky Way.

The IMBH search will open a new path of research in the understanding of supermassive black holes – black holes that can be billions of times larger than the mass of the Sun, which sit at the center of most massive galaxies, including the Milky Way.


“It is widely accepted that black holes with masses greater than a million solar masses lurk at the centers of massive galaxies,” the team wrote. “[But] the origins of such super-massive black holes remain unknown.”

One of the prominent theories about how super-massive black holes form is through IMBHs merging at the center of galaxies, acting as seeds to create their larger counterparts. This would help explain how super-massive black holes managed to get so massive so quickly—they appeared when the universe was just a few hundred million years old.

The researchers also say identifying and studying an IMBH will expand our understanding of the universe more generally.

“Theoretical studies have predicted that 100 million to one billion black holes should exist in the Milky Way, although only 60 or so have been identified through observations so far,” the authors continue.

“Further detection of such compact high-velocity features in various environments may increase the number of non-luminous black hole candidate and thereby increase targets to search for evidential proof of general relativity. This would make a considerable contribution to the progress of modern physics.”

Researchers will now continue to study the candidate IMBH in the hope of confirming its nature.
