Collisional Galaxy

Today's Astronomy Picture of the Day shows NGC 922 in the constellation of Fornax. NGC 922 has been distorted as the result of a collision with another galaxy; this image is a combination of a visible light shot (taken by the Hubble Space Telescope) and an x-ray shot (taken by the Chandra X-Ray Observatory) that shows the "shocking" resulting from the merger.
