Globular Cluster
Globular cluster explained in an easy to understand way:

Imagine trying to fit all your clothes, shoes, and accessories into a single, compact suitcase for a long trip. This scenario is similar to a globular cluster, where a large number of stars are densely packed into a spherical area in space. Just as each item in your suitcase represents a star in the cluster, both situations involve fitting many components within a limited space, creating a cohesive and organized whole.
