WASHINGTON (Reuters) – The large majestic cloud is a dwarf galaxy located near the Milky Way, and visible to the naked eye as a luminous plane of light from the southern hemisphere of the Earth and called the name of the Portuguese explorer Ferdinand Magelan, who noted this five centuries ago. The new research now provides a complete understanding of our Hungarian neighbor’s makeup.
A study based on a nine -motifist that was observed on the sidelines of the Milky Way method provides strong evidence of the presence of a super black hole inside the large Magilant cloud. Most galaxies are believed to have a black hole in their heart, but this represents the first evidence of one inside the big Magilant cloud.

According to researchers, data related to the path of these stars indicate that she was coming out of the big cloud from Magellanic after a closely meeting with this black hole. Black holes are exceptionally dense with very strong gravity so that light cannot even escape.
The large Magellanic cloud is about 160,000 light -years from Earth, making it among the nearest galaxies to the Milky Way. This makes this the closest super -superior black hole alongside the hole called the A*, or SGR A*, located in the heart of the Milky Way. SGR A* about 26,000 light years of Earth. The optical year is the light distance per year, 5.9 trillion mile (9.5 trillion km).
Just as the Milky Way method is much more huge than the large majestic cloud, SGR A* is more large than the newly identified black hole, which is among the least known black holes. SGR A* It has a mass of 4 million times larger than the sun. This one has a mass of about 600,000 times larger than the sun.
SGR A*, in turn, by some high -end black holes discovered in other large galaxies such as one with a mass greater than 6.5 billion times of the sun in a galaxy called mess. This is one and SGR A* are the only black openings by astronomers.
The new study focused on a category of stars called Hypervelocity stars. It is produced when the dual stars system – two stars linked to each other – are very close to a super black hole.
“The intensive gravitational forces tear the husband,” said Jesse Han, a physician in Harvard astronomical.
The sun travels across space about 450,000 miles per hour (720,000 km per hour) while Hypervelocy stars do this several times so quickly.
The researchers used data from the Gaia Space Observatory at the European Space Agency, which followed more than a billion stars in our galaxy with an unprecedented precision.
There are 21 stars known as the known level in the Milky Way. Astronomers have identified the trust of 16 of them, as they tracked seven of them to SGR A* in the heart of our galaxy and the other nine return to the large Magellanic cloud.
Han said: “The only reasonable interpretation is that the large Magharani cloud includes a super black hole in the middle, and it is similar to SGR A in our galaxy.”
Han said: “It is completely expected that the big cloud of Maglani, given its bloc and structure, will contain a super black hole in this mass. We only needed to find evidence for this.” “It’s fun and exciting, but also something really logical.”
To date, the nearest black hole behind the Milky Way was the hole inside the Andromeda galaxy, about 2.5 million light -years away from the ground. It is the closest galaxy to the Milky Way.
The astronomer and the study participating in the study said: “The big cloud of Magelanik is one of the best studied galaxies, however this super -black hole has not only indirectly by tracking the origins of fast stars.
