Cen A looks a lot different when using an x-ray telescope. Here, a jet of gas moving at half the speed of light is heated to millions of degrees by a supermassive black hole in the galaxy’s core. A sea of million-degree gas fills the galaxy while points of x-ray light reveal “x-ray binaries”: neutron stars or black holes ripping gas off nearby stellar companions. Credit: NASA/SAO/R.
