A #Globular #Cluster is a tightly bound, spherical collection of hundreds of thousands to millions of old stars that orbits a galactic core.
Globular clusters generally form early in the galaxies’ histories in regions rich in gas and dust. Since the stars form from the same cloud of gas as it collapses, they typically hover around the same age.
The #globular star clusters M13 and M3. This direct comparison nicely shows the difference in apparent diameter between the two.
