When one first focuses on the Ultra Deep Field image, captured by the Hubble Space Telescope in 2004, it appears to be just a photo of the night sky. Dots, stars at first glance, clutter the image, but a longer, closer look leads to wonder and amazement. The image, which is a piece of the sky about the size of a penny at arm's length, shows that the "stars" are really galaxies, an estimated 10,000!
