Scientist controlling the Hubble Space telescope decided one day to see if they could find anything in some of the dark area's of the sky. They looked for the darkest area in space that they could find and focused the telescope on that small patch of black sky. No one really thought they would find much in that small spot (about the size a dime would appear from a mile away). They focused on the spot for a million seconds collecting one photon per minute. They were amazed by what they found. Each spot in the picture below is a galaxy and they found 10,000 galaxies. Each galaxy of course contains billions of stars. The universe just got a lot bigger.
