NGC 2808

Located in the direction of Carina, it lies about 31,300 ly from Earth and, with a mass of around 1.4x106 solar masses it is one of the most massive globular clusters in our galaxy. Contrary to the accepted theory of globular cluster star formation (all stars have roughly the same age) this cluster contains three distinct populations by age, implying that the mechanism of this cluster's star formation occurred by a different process in a radically different environment. 

Classified as I (high concentration towards the centre) on the Shapley-Sawyer globular cluster concentration scale (1927).
