Constructing the Hertzsprung-Russell Diagram for Globular Star Cluster

About this video
Duration: 1 minute, 33 seconds

A Hubble Space Telescope color image of the core of the globular star cluster Omega Centauri is used to construct a Hertzsprung-Russell diagram of the stellar populations in the cluster. When stars are sorted by brightness and color they can be used to create a graph that astronomers use to trace stellar evolution.
