This image provided by NASA of an infrared photograph taken with NASA's Spitzer Space Telescope revealing a never-before-seen dust ring deep within the Andromeda galaxy (near center of the image). When combined with a previously observed outer ring, according to scientists the presence of both dust rings suggests that M32 plunged through the disk of Andromeda along Andromeda's polar axis approximately 210 million years ago. The presence of both dust rings suggests a long-ago disturbance whose effects arestill expanding outward through Andromeda.(AP Photo/NASA/JPL)
