Messier 13 (M13, NGC 6205) is a magnitude 5.8 globular cluster in the constellation
of Hercules, and is located at a distance of about 25,100 light years. It has an
apparent size of 20 arc minutes and is a beloved visual object which never fails to
give a good show in scopes large and small. It contains several hundred thousand
stars, and like other globs, is made up of very old stars, with ages estimated at 14 to
24 bilion years old. (SEDS)
