Description:
The Omega Centauri Globular cluster is the largest globular cluster in the Milky Way Galaxy, and is located 15,800 light years away in the constellation of Centaurus. With probably over a million stars, and a combined mass of over 4 million suns, Omega Centauri is the brightest globular cluster that can be seen from Earth, shining at a visual magnitude of +3.9, an easy target with the naked eye from suburban skies.
Because of the unique features of Omega Centauri that distinguishes it from other globular clusters, it is thought that it originated as a separate dwarf galaxy that got consumed by the Milky Way.
