NGC 922 is a ring galaxy created by the collision of a large and small galaxy about 300 million years ago, and it’s got more than it’s share of black holes. Astronomers aren’t sure why. The collision sent ripples of high density gas out from the impact point near the center that partly condensed into stars. This image of NGC 922 was taken by the Hubble Space Telescope. Observations of the galaxy using the Chandra X-ray Observatory, however, show several glowing X-ray knots that are likely large black holes. NGC 922 spans about 75,000 light years and lies about 150 million light years away. It can be seen with a small telescope toward the constellation of the Fornax (The Furnace).
