 Here's a Hubble image of the center of nearby active galaxy IC 5063. It contains a supermassive black hole. As material approaches the black hole's event horizon, massive amounts of radiation is released in all directions. But note the V-shaped shadows emanating from the central core. Astronomers suggest that a ring of dusty material surrounds the black hole and may be casting its shadow into space by blocking some of this radiation. These dark shadows extend across at least 36,000 light years.
