Globular clusters can be used to tell us the age of galaxies. They are found orbiting in a "cloud" around galaxies, and there is no mechanism currently known which will produce much new star formation in most members of this class of objects.

M41 is a globular cluster easily located four degrees south of Sirius. Perhaps a hundred or so stars make up this bright group, fifty of them bright enough to be easily seen in binoculars. At the centre of the group is a red giant.

The oldest globular clusters contain only stars less massive than 0.7 solar masses. These low- mass stars are much dimmer than our Sun. This observation suggests that the oldest globular clusters are between 11 and 18 billion years old.

Globular clusters are especially nice because they are bright, compact (thus long-lasting) and can be seen a long way off.

Most of the stars in the central bulge and in the globular clusters of the galactic halo are old, low metals stars, and halo stars account for only 0.1 to 0.2 percent of the stars near Sol.
