M31, or the Andromeda Galaxy is the nearest large spiral galaxy to our own. In fact, it is believed that our galaxy and this galaxy will collide in the near future (several thousand years from now). Don't worry, none of us will be around to see it. Our Milky Way galaxy is a similar shaped spiral, but scientists believe it to have a barred structure with more arms. The small elliptical galaxy M110 is visible in the lower right.
