A Globular Star Cluster Collection
This collage shows a range of globular clusters that were studied using the Hubble Space Telescope and the MPG/ESO 2.2-meter telescope at the European Southern Observatory's La Silla Observatory in Chile. The data show that, despite all forming at roughly the same time, the clusters have aged at dramatically different rates with heavier stars sinking to the centers of the clusters in a process similar to sedimentation.
