Star 'starving' black hole is a billion light years from Earth
American astrophysicists discovered that a "super-thin" black hole has no surrounding stars, a phenomenon that is rarer than the two black holes.
According to Phys.org, Julie Comerford researcher at the University of Colorado announced the discovery during the annual meeting of the American Astrophysics Association on January 5 in Kissimmee, Florida.
Until now, scientists have only discovered 12 galaxies exist with two black holes in the middle. Typically, galaxies have a supermassive black hole located in the center with a mass of between one million and a billion times that of the Sun.

However, in newly discovered galaxies, one of the two black holes is much smaller than the remaining black hole and is in a "starving" state. Black holes are often surrounded by stars, but this black hole is completely bare.
According to Comerford's speculation, small black holes lose weight during the two galaxies colliding and merging as one. This may also be a rare example of a medium-sized black hole, which is likely to change over time into a supermassive black hole. The mass of the black hole on average is 100 to 1 million times greater than the Sun.
Comerford uses the Hubble space telescope along with the Chandra X-ray Observatory of the US Aerospace Agency (NASA) and discovered the galaxy of two black holes a billion light-years from Earth last year. This galaxy is denoted as J1126 + 2944 . Comerford's research may contribute to shedding light on the evolution of black holes.
