The black hole at the center of this galaxy is part of a survey of 18 of the biggest known black holes in the universe. This large elliptical galaxy is in the center of the galaxy cluster PKS 0745-19, which is shown in this composite image containing X-rays from Chandra (purple) and optical data from Hubble (yellow). Researchers found that the black holes in the survey may be about ten times more massive than previously thought. This includes at least ten that could weigh between 10 and 40 billion times the mass of the sun, making them "ultramassive" black holes.
