Globular cluster evolution. Computer simulation showing the evolution of a globular cluster containing 2500 stars. Initially the stars are distributed randomly. As time progresses gravitational interactions cause low mass stars to be ejected from the cluster, while high mass stars aggregate at the centre of the cluster. Globular clusters are collections of old stars that orbit a galaxy's core.
