The presence of this second galaxy by the Swift satellite detected the dam Chandra X-Ray Observatory NASA.
Although both the black hole at the center of the galaxy, both separated by a distance of about 11 thousand light years or about one-third the distance of our solar system with the center of our galaxy. As an illustration, one light year is about 10 trillion kilometers.
Second black hole found was also a very active black holes and into the classification of 'supermassive' meaning, each has a mass equal to millions or even billions of times the mass of stars like our sun.
In fact, the usual black hole formed by collapse of giant stars measuring only 10 to 20-fold compared with the mass of the Sun.
"At the center of most of the giant galaxies, including the Milky Way, is a supermassive black hole that weighs millions of times more than the mass of the Sun," Michael Koss, researchers from NASA, as quoted from Space, June 11, 2011. "Some of them emit radiation billions of times more energy than the Sun," he said.
However, Koss said, although the supermassive black hole is a common phenomenon that is present in the center of the galaxy, not all black holes emit radiation energy is called the 'active galactic nuclei (AGN). "Therefore, get a giant black hole actively extremely rare. Moreover, find two giant black holes in one galaxy, "he said.
Astronomers suspect that this pair of supermassive black holes are formed when a galaxy is destroyed.
"If two galaxies collide, and each has a supermassive black hole, there is a possibility that the two black holes become active as an AGN," says Richard Mushotzky, another researcher from the University of Maryland. (Umi)
