  2. The "Hubble Deep Field" image was taken by the Hubble Space Telescope December 18 - 28, 1995. It was taken of a region near the handle of the Big Dipper, and covers a patch of sky about only 0.05 degrees across (equivalent to the width of a dime viewed 75 feet away). This region was chosen because there are very few stars there. So nearly every object in the image is a galaxy.

    Your teacher will show you a portion of the Hubble Deep Field image. Identify the types of the ten galaxies labeled on the Deep Survey Image.
