NGC 5139 "Omega Centauri"

About this object

Omega Centauri (ω Cen) or NGC 5139, is a globular cluster in the constellation of Centaurus that was discovered by Edmond Halley in 1677. Located at a distance of 15,800 light-years, it is the largest globular cluster in the Milky Way galaxy. Omega Centauri is so distinctive from the other galactic globular clusters that it is thought to have an alternate origin as the core remnant of a disrupted dwarf galaxy.[
