Check out this link from the Hubble Space Telescope called the “Hubble Ultra Deep Field” (HUDF), the deepest image of the universe ever taken in visible light. Some browsers will show this as a small picture, and you should be able to click on it to blow it up quite a bit. There’s a lot of other really interesting pictures on this site too.
