A massive Black Hole got discovered near the centre of the galaxy Milky Way. Reports claimed that it is approximately 100,000 times more gigantic than our sun, and it is lurking in a toxic gas cloud near the centre of Milky Way galaxy.
If the information gets confirmed then after the super large Sagittarius A* which is located at the almost close to the core of the galaxy, will get ranked as the second biggest Black Hole in the Milky Way.
According to the General Relativity Theory, prescribed by Albert Einstein in 1915, the formation of black holes takes place from the violent collision of two dying stars. Once a black hole formed, it continues to expand by fascinating accumulation from its surroundings. Black holes, by absorbing other nearby stars and integrating them with other black holes, turn into supermassive black holes, which might range more than of millions of solar masses.
As per the observations made till date, scientists have divided black holes into two categories — stellar weight black holes that are just ten times the mass of Sun and super massive black holes that are millions or billions of times the mass of Sun and scientists have not seen any anomaly or deviation from this division.
Previously, NASA’s Chandra X-ray Observatory, as well as NASA’s NuSTAR and CSIRO’s ATCA, have discovered tightly coupled black hole and white dwarf star with the smallest orbit in Milky Way.
The team has claimed it as the rarest discovery because when such a pair involving a dying star (that would later become a black hole) and another star exists, the gravitational pull on the part of the dead star is so large that the companion star doesn’t usually last this long. Meaning, as soon as the black hole is formed, the matter from the companion star is sucked into itself by the black hole, and eventually, the companion star ceases to exist.
In Japan, Astronomers from the Keio University using the ALMA telescope in Chile were detecting a gas cloud to understand the movement of its gases. They observed that molecules in the elliptical cloud, which is 200 light years from the heart of the Milky Way galaxy and 150 trillion kilometres wide, were being bounced back by enormous gravitational forces.
According to computer models, the most likely cause was a black hole, not more than 1.4 trillion kilometres across. The scientists and researchers also observed radio waves coming from the core of the cloud which showed the signs of the presence of a black hole.
Astronomer at Keio University, Tomoharu Oka said, “This is the first detection of an intermediate-mass black hole candidate in the Milky Way galaxy.”
Mr Oka told ‘The Guardian’, “The newly-found black hole could be the core of an old dwarf galaxy that was cannibalised during the formation of the Milky Way billions of years ago.” In time, the object will be drawn towards Sagittarius A* and sink into it, making the supermassive black hole at the heart of the Milky Way even more massive, Mr Oka said.
The journal Nature Astronomy published the research.
According to a recent research paper, Supermassive black holes pull apart and gulp down the nearby ill-fated stars a hundred times more frequently than the earlier prescribed statistics. As per the previously established hypothesis, such cosmic cannibalism – supermassive black holes eating stars hundred times more often was extremely uncommon and used to take place once in every 10,000 to 100,000 years for each galaxy.
