2 Big Black Hole at the Galactic Center Found Markarian 739
Of a further research, astronomers found that Markarian 739, a galaxy which is about 425 million light-years from Earth towards the constellation Leo has not only a giant black hole, but two black holes at the center of the galaxy.
Of a further research, astronomers found that Markarian 739, a galaxy which is about 425 million light-years from Earth towards the constellation Leo has not only a giant black hole, but two black holes at the center of the galaxy.
The presence of these two galaxies are detected by the Swift satellite dams Chandra X-Ray Observatory NASA.
Although both the black hole at the galactic center, they are separated by a distance of about 11 thousand light-years or about one-third the distance of our solar system with the center of the Milky Way. As an illustration, one light year is about 10 trillion kilometers.
Both black holes are found it is also a very active black holes and into the classification of 'supermassive' which means, each having a mass equal to millions or even billions of times the mass of stars like our Sun.
In fact, ordinary black holes formed by the collapse of massive stars is only a 10 to 20-fold compared with the mass of the Sun.
"At the center of most massive galaxies, including the Milky Way, is a supermassive black hole that weighs millions of times more than the mass of the Sun," said Michael Koss, researchers from NASA, as quoted from Space. "Some of them emit radiation billions of times greater energy than the Sun," he said.
However, Koss said, although the supermassive black hole is a common phenomenon that is present in the centers of galaxies, not all black holes emit radiation energy is called 'active galactic nuclei (AGN).
"Therefore, get a giant black hole actively extremely rare. Moreover, the finding of two giant black holes in one galaxy, "he said. Astronomers suspect that this pair of supermassive black holes form when there are galaxies that were destroyed.
"If two galaxies collide, and each has a supermassive black hole, there is the possibility that the two black holes become active as AGN," says Richard Mushotzky, another researcher from the University of Maryland.
