This globular cluster, known as M3 or Messier 3, brightens the sky in the constellation Canes Venatici. It is roughly 33- to 39,000 light years away. Globs are interesting, and they become more interesting the deeper one can see into them. They contain so many stars that no telescope from earth could see them all. One can always go deeper! Yet deeper images and larger telescopes make the objects fascinating.
