Omega Centauri: the brightest globular cluster
This huge ball of stars predates our Sun. Long before mankind evolved, before the dinosaurs roamed and even before the Earth existed, several star globes condensed and orbited a young galaxy, the Way Milky Of the approximately 200 globular clusters that survive today, Omega Centauri is the largest, with some ten million stars. Omega Centauri is also the brightest globular cluster: with an apparent visual magnitude of 3.9 it is visible to the naked eye for southern observers. Cataloged as NGC 5139, Omega Centauri is about 18,000 light years away and is 150 light years across. Unlike many other globular clusters, Omega Centauri stars have different ages and several chemical traces, indicating that this 12-billion-year globular cluster has a complex history.
