This is a wide view of the Virgo Cluster of galaxies centered on M87. Many other bright
galaxies can be seen in this image, including part of Markarian's Chain and The Eyes. M87 itself has an enormous, active black hole in the center that is launching a
jet of material out of the galaxy at 99% the speed of light!
