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 is more morphologically 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 × 106 M☉, [11] and a supermassive black hole with an estimated mass 4.7 × 106 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]

<span class="mw-page-title-main">NGC 4178</span> Galaxy in the constellation Virgo

NGC 4178 is the New General Catalogue identifier for a barred spiral galaxy in the equatorial constellation of Virgo. It was discovered April 11, 1825 by English astronomer John Herschel. Located some 43.8 million light years away, this galaxy spans 2.3 × 0.4 arc minutes and is seen at a low angle, being inclined by 77° to the line of sight from the Earth. The morphological classification of NGC 4178 is SB(rs)dm, indicating that it has a bar feature at the core, and, per the '(rs)', has traces of a ring-like structure surrounding the bar. The 'dm' suffix indicates the spiral arms are diffuse, broken, and irregular in appearance with no bulge at the nucleus. This galaxy is a member of the Virgo Cluster, which is the richest nearby group of galaxies outside the Local Group and forms the core of the Virgo Supercluster.
