NGC 5746
NGC 5746 (also known as the Mini Sombrero Galaxy) is a barred spiral galaxy located in the eastern part of the constellation of Virgo (constellation), Virgo. It was discovered on 24 February 1786 by Germany, German-British astronomer William Herschel. It is the lead member of the NGC 5746 Group of galaxies (also known as Lyons_Groups_of_Galaxies, LGG 386), itself one of the Virgo III Groups strung out to the east of the Virgo Supercluster of galaxies. Characteristics NGC 5746 is located at a distance of 99 million light years and is seen nearly edge-on, bearing a strong resemblance with the galaxy NGC 4565, that is also seen nearly edge-on. As with the former, it has a box-shaped bulge that is actually a barred spiral galaxy, bar seen from one side and a currently modest star formation activity. Investigations with the help of the x-ray space telescope Chandra seemed to detect a large cloud of gas surrounding NGC 5746 that was thought to be remnant gas of its formation in t ...

New General Catalogue
The ''New General Catalogue of Nebulae and Clusters of Stars'' (abbreviated NGC) is an astronomical catalogue of deep-sky objects compiled by John Louis Emil Dreyer in 1888. The NGC contains 7,840 objects, including galaxies, star clusters and emission nebulae. Dreyer published two supplements to the NGC in 1895 and 1908, known as the ''Index Catalogues'' (abbreviated IC), describing a further 5,386 astronomical objects. Thousands of these objects are best known by their NGC or IC numbers, which remain in widespread use. The NGC expanded and consolidated the cataloguing work of William and Caroline Herschel, and John Herschel's ''General Catalogue of Nebulae and Clusters of Stars''. Objects south of the celestial equator are catalogued somewhat less thoroughly, but many were included based on observation by John Herschel or James Dunlop. The NGC contained multiple errors, but attempts to eliminate them were made by the ''Revised New General Catalogue'' (RNGC) by Jack W. Sulent ...
