Globular big determine cluster Omega Centauri, also is called NGC 5139, is a pair of 15,000 light-years away. The cluster is filled with about 10 million stars great older than the Sun internal a volume about 150 light-years in diameter. Or no longer it’s the greatest and brightest of 200 or so known globular clusters that gallop the halo of our Milky Draw galaxy. Though most big determine clusters consist of stars with the same age and composition, the enigmatic Omega Cen exhibits the presence of rather a pair of stellar populations with a unfold of ages and chemical abundances. In actual fact, Omega Cen may perhaps furthermore very well be the remnant core of a runt galaxy merging with the Milky Draw.
