At the center of the Centaurus galaxy cluster, there is a large elliptical galaxy called NGC 4696. Deeper still, there is a supermassive black hole buried within the core of this galaxy. New data from NASA’s Chandra X-ray Observatory and other telescopes has revealed details about this giant black hole. via NASA http://ift.tt/2oOFlkG
