RX J1532: Extremely Powerful Ultramassive Black Hole Discovered

This is a composite image of the galaxy cluster RX J1532.9+3021, located about 3.9 billion light years from Earth. The labels show the location of two enormous X-ray cavities, created by jets from a central black hole that have pushed aside hot gas. Image credit: X-ray – NASA / CXC / Stanford / J.
