NGC 1892 is a spiral galaxy located approximately 51 million light-years away [5] the constellation Dorado. It was discovered November 30, 1834 by John Herschel. [3] NGC 1892 is a member of the NGC 1947 Group [6] [7] [8] which is part of the Southern Supercluster. [7]

NGC 1892, despite being a spiral galaxy, has a central bulge which is morphologically more similar to dwarf irregular galaxies. The galaxy's central bulge which is highly irregular, is obscured by a dust lane. [9] NGC 1892 is also host to a nuclear star cluster [10] with an estimated mass of 7.381 million M☉, [11] and a supermassive black hole with an estimated mass 4.7 million M☉. [12]

A probable supernova of type IIP was photographed by the Carnegie-Irvine Galaxy Survey (CGS) in 2004, [13] but it was not noticed until Brazilian amateur astronomer Jorge Stockler de Moraes compared the CGS image to one he took in January 2017. [5]
