Globular Star Clusters contain some of the oldest known stars.
They generally are comprised of several thousand to a half-million
stars in a ball-shaped mass. Globular Star Clusters are a part
of our Milky Way Galaxy, but they do not lie in the plane of our
galaxy like Open Star Clusters do, instead they orbit around
the center of our galaxy as part of the "halo" of our galaxy.
The following pictures show a sample of Globular Clusters, the
brightest stars in these clusters are the Giants and
Supergiants, which can be seen best in the last two pictures as
yellow, orange, and reddish colored stars.
