• Location in a galaxy: In a halo about a galaxy.
• Color of the brightest stars in a globular cluster: Red - red giant stars typcially with an absolute magnitude of -2.

• A globular cluster is a spherical collection of stars that orbits a galactic core as a satellite. Globular clusters are very tightly bound by gravity, which gives them their spherical shapes and relatively high stellar densities toward their centers.

• However there are more differences than similarities. Star clusters come in two varieties: open and globular. Open clusters are irregular in shape and globular clusters are spherical . Galaxies are usually elliptical or spiral in shape, but there are irregular ones.

A Globular cluster is a collection of stars where the population count can go as much as few millions. These clusters are tightly bound by gravity, and hence, tend to be more spherical than the less dense open clusters. What is much more fascinating is that Globular clusters contain very old stars, while open clusters have relatively younger ones.
