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)
