Messier 45, The Seven Sisters, or The Pleiades

Ever think hey, the Pleiades look kinda fuzzy? Well, you would be right if you had that thought. This is an open cluster / reflection nebula. The remnants of the nebula (gasses) that created the Pleiades are lingering around the stars. The light from the stars reflects off of this gas, and because the cooler colors (blue) are shorter wavelengths, they scatter more easily. This is also why our sky is blue.
