…and caused the puffing up of the thick disc. The globular clusters firmly identified as former Sausage members are Messier 2, Messier 56, Messier 75, Messier 79, NGC 1851, NGC 2298, and NGC 5286. NGC 2808 is another globular-like cluster of the Sausage. It is composed of three generations of stars, all born…
