Globular cluster. Illustration of a globular star cluster seen over a coast on a hypothetical planet. A moon of the planet is seen at upper right. Globular clusters are densely packed balls of thousands to millions of stars,formed at the same time. They are thought to contain some of the oldest stars known,and exist in a halo around the galaxies,rather than in the disc along with the majority of other stars | |
