NGC 1856 is a young, massive star cluster similar to a "blue globular cluster"[3] in the Magellanic Clouds in the constellation Dorado. Its age was initially reported estimated to be 80 million years,[3] and later estimated to be around 300 million years [4] The object was discovered in 1826 by James Dunlop with a 9-inch reflecting telescope.[5]
