NGC 1892 is a spiral galaxy located approximately 51 million light-years away the constellation Dorado. It was discovered November 30, 1834 by John Herschel. NGC 1892 is a member of the NGC 1947 Group which is part of the Southern Supercluster.
NGC 1892 despite being a spiral galaxy, has a central bulge is more morphologically similar to dwarf irregular galaxies. The galaxy's central bulge which is highly irregular, is obscured by a dust lane. NGC 1892 is also host to a nuclear star cluster with an estimated mass of 7.381 × 10 M☉, and a supermassive black hole with an estimated mass 4.7 × 10 M☉.
A probable supernova of type IIP was photographed by the Carnegie-Irvine Galaxy Survey (CGS) in 2004, but it was not noticed until Brazilian amateur astronomer Jorge Stockler de Moraes compared the CGS image to one he took in January 2017.
