NGC 1892
Spiral galaxy in the constellation Dorado
From Wikipedia, the free encyclopedia
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]
