M13 (Messier 13) is a globular cluster containing roughly one million stars in the halo of the Milky Way. It lies in the constellation Hercules, 25,000 light years from the Sun. The SDSS obtains images in five filters, allowing these stunning multi-color images to be made. In particular, the range of colors of stars, from red giants to so-called blue straggler stars, is apparent in this image.
