Spiral galaxy in the constellation Dorado
NGC 1892 is aspiral galaxy located approximately 51 millionlight-years away[ 5] the constellationDorado . It was discovered November 30, 1834 byJohn Herschel .[ 3] NGC 1892 is a member of theNGC 1947 Group [ 6] [ 7] [ 8] which is part of theSouthern Supercluster .[ 7]
NGC 1892, despite being a spiral galaxy, has a centralbulge which is morphologically more similar todwarf irregular galaxies . The galaxy's central bulge which is highly irregular, is obscured by a dust lane.[ 9] NGC 1892 is also host to anuclear star cluster [ 10] with an estimated mass of 7.381 × 106 M ☉ ,[ 11] and asupermassive black hole with an estimated mass 4.7 × 106 M ☉ .[ 12]
A probablesupernova of typeIIP was photographed by theCarnegie-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]
