What Can Be Observed in Globular Clusters?

Abstract

These tightly packed star clusters are indeed shaped like a globe, hence the name. They contain the most ancient stars within our Galaxy. As the Milky Way contracted, some concentrations of material formed in a halo surrounding the core. Stars formed within these huge concentrations of dust and gas, then those stars attracted one another and became the globular clusters. There are just over one hundred globular clusters gliding around the center of the Galaxy, most of them located near the Core. Therefore, the constellations of Sagittarius, Scorpius, Centaurus and Ophiuchus are filled to the brim with these enchanting globes of stars.
