The Hubble Deep Field was an image taken by the Hubble Space Telescope over a period of about ten days, of a particularly dark patch of sky. If you looked in this area for a minute you would see nothing. Stray photons of light were captured and collected, and stacked and filtered, and the result revealed the light from thousands of distant galaxies. By measuring the number of degrees across the photo, and counting the galaxies, it became possible to estimate the number of galaxies in our universe.

There are about one hundred billion of them, or 100,000,000,000. That is a one followed by eleven zeroes, or 1 x 10^11 in scientific notation. Any way you say it, it is still a lot.
