Found second black hole in center of galaxy

Other supermassive black hole was found in the center of a galaxy close to Earth that was already identified another hole, scientists reported in an article in The Astrophysical Journal Letters.
The galaxy known as NGC 3758 Markarian 739 or is located 425 million light years from Earth in the constellation Leo. The astronomers found that the two nuclei of the galaxy are separated by 11 thousand light years and each contains a black hole that consumes the gas falling into it.

The scientists used data from the Swift satellite and Chandra X-ray Observatory to find the second supermassive black hole, according to the U.S. space agency (NASA) on its website.
Markarian 739 was observed with visible light but was not detected anything until Chandra and Swift provided data that showed another nucleus.

"In the vast majority of the hearts of galaxies, including our own Milky Way, are supermassive black holes weighing millions of times the mass of their soles. Some of them also radiate billion times the energy of their stars, "said Michael Koss, leader of the team that published the article and a researcher at Goddard Space Flight Center of NASA and researcher at the University of Maryland at College Park.
The centers of the galaxies that are so intense emissions are known as active galactic nuclei (AGN), these are the areas that are generally black holes, but only 1% are considered so powerful AGN.
The binary system of AGN has Markarian 739 is the second to the scientists found. Many scientists believe that major disasters such as galaxy collisions can form the AGN, the disclosure of information which would help clarify to understand the origin of the universe.
Since 2004, the telescope Swift BAT ship has been creating a map of the sources of high energy X-rays across the sky. This probe is sensitive to AGN that are more than 650 million light years away from Earth.
