Mystery Object in Cygnus A Galaxy (http://www.skyandtelescope.com/wp-content/uploads/cygnus_a_new_source_480px-300x171.jpg) This false-color infrared image from the Keck II telescope shows the galaxy Cygnus A. Its central supermassive black hole is the large red-black splotch, but this 2003 image reveals a second, mystery source (circled) nearby. G.
