Millions of stars shine brightly in the Hubble Space Telescope Classic image of the globular star cluster Omega Centauri. This image shows the cluster's core, which contains only 2 million stars. The entire cluster is home to 10 million stars.

Globular clusters like this one are roughly spherical groups of stars bound together by mutual gravitational forces.

Omega Centauri is about 17,000 light years away.
