The Universe ~ The Search for Cosmic Clusters

The Pleiades star cluster (which is an example of an open cluster)

Today on Far Future Horizons we present another exciting episode of the acclaimed History Channel series The Universe, concerning the Search for Cosmic Clusters.

Cosmic clusters are the one-stop-shopping places for learning all about the nature, variety and evolution of stars in the Universe. 

A Globular Cluster

They are unique, because in clusters, all the stars were born at about the same time, from the same material and all are at the same approximate distance from Earth. This means we can be sure that any differences among them are due to their true natures and not distorted by different distances from Earth and other factors.
