Omega Centauri: The Largest and Brightest Star Cluster





12 billion years old, Omega Centauri (NGC 5139) is a globular cluster that is both the brightest and the largest known globular cluster associated with our galaxy.

It was discovered by Edmond Halley in 1677 (of Halley’s comet fame) although was earlier listed in Ptolemy’s Catalog of the Stars over 2000 years ago as a star. It was first recognized as a globular cluster by the English astronomer John William Herschelin in the 19th century.

Long a source of interest for astronomers, Omega Centauri has naturally also gained plenty of interest from NASA.

Here’s a few more shots of this amazing feature of the galaxy from a variety of telescopes.
