Graphics: The suspected Black Hole is revealed by the tear of a star that ventured Too Close

A team of astronomers has found what it says is The Best proof, however, for an elusive class of Black Holes .

you say, the supposed "intermediate-mass Black Hole betray their existence by tearing apart a wayward star that ventured Too Close .

This medium-sized objects are a long-sought "Missing Link " in the evolution of the cosmos.

the researchers used two x-ray observatories, which together can realize the object.

"intermediate-mass Black Holes are very elusive objects, and so it is important to carefully consider and exclude alternative explanations for each of the candidates, said Dr. Dacheng Lin, from the, who led the study.

"that is what has allowed Hubble to do, for our candidates. "

In 2006, Nasa's orbiting and the European Space Agency discovered a powerful X-ray flare 3XMM J215022 named. 4-055108.

The Type of X-ray flare meant that it could be explained by only two scenarios, according to Dr. Lin. It was interfere with "either a remote (outside our galaxy), intermediate - mass Black Hole and swallow a star or a cool star at the end of the neutron in our galaxy," he told Bbc News .

neutron stars are the crushed remains of an exploded star.

In order to between the two scenarios, which was the Hubble space telescope, pointed to the X-to-fix-ray source, and their exact location. The Telescope provided strong evidence that the X-emanated rays, not of one isolated source in the Milky Way , but in a far-flung, dense star clusters at the edge of another galaxy.

This Was exactly the kind of place that the astronomers expected that a medium-sized Black Hole . Dr. Lin said, the Hubble data from the "most likely" explanation.

so-called supermassive Black Holes are often found in the centers of galaxies, like our Milky Way hosts a massive Central Black Hole , called Sagittarius A*.

But intermediate-mass Black Holes were particularly difficult to find because they are smaller and less active than The Massive types. In addition, you don't have to act so much in the vicinity of cosmic material as a fuel, and it is missing to pull the strong pull required number of stars to the inside to produce X-ray flares.

astronomers are effectively a medium-sized Black Hole red-handed - in fact, had to catch up and devoured a star.

Dr. Lin and his colleagues had to find comb through thousands of XMM-Newton observations, to be a candidate.

The Hubble-Space-telescope was used for the solution of the position of the X-ray source

The X-ray-lights of the tattered star, allowed astronomers to estimate the mass of the Black Hole , the 50,000 times the mass of The Sun .

This. But since the object will tear a star apart, this evidence convincing, yet, according to Dr. Lin's team. A Nasa video of how the Black Hole is perhaps The Star of the show:

intermediate-mass Black Holes consumed the key to many questions about Black Hole evolution are visualized. For example, a super mass-rich Black Holes grow from a mid-size?

the astronomers also want to understand how the medium-sized Black Holes form, and whether or not they tend to pile in dense star, such as this one.

"the study of The Origin and development of the intermediate-mass Black Holes is finally an answer to the question, to exist as the super-massive Black Holes , we came in the centers of massive galaxies," said team member Dr. Natalie Webb, of the
