NGC 5308 is an edge-on lenticular galaxy in the constellation of Ursa Major. It was discovered on 19 March 1790 by William Herschel. [5] It was described by John Louis Emil Dreyer as "bright, pretty large" when he compiled the New General Catalogue. [6] A small, irregular galaxy near NGC 5308 has been given the designation LEDA 2802348. [7]

NGC 5308 was imaged by the Hubble Space Telescope in 2016. The galaxy appears to be a flat, smooth disk, typical of most lenticular galaxies. Many large globular clusters orbit the galaxy; these are visible as tiny dots surrounding the galaxy, and are mostly made of old, aging stars similar to the galaxy itself. [8]

NGC 5322 Group

According to A.M. Garcia, the galaxy NGC 5308 is a member of the NGC 5322 group (also known as LGG 360), which contains at least 10 other galaxies, inclulding NGC 5322, NGC 5342, NGC 5372, NGC 5376, NGC 5379, NGC 5389, UGC 8684, UGC 8714, and UGC 8716. [9]

Supernova

One supernova has been observed in NGC 5308: SN 1996bk (type Ia, mag. 14.5) was discovered by Piero Mazza and Stefano Pesci on 12 October 1996, located 10.5" south and 17.9" west of center of the galaxy. [10] [11]

Messier 100 is a grand design intermediate spiral galaxy in the southern part of the mildly northern Coma Berenices. It is one of the brightest and largest galaxies in the Virgo Cluster and is approximately 55 million light-years from our galaxy, its diameter being 107,000 light years, and being about 60% as large. It was discovered by Pierre Méchain in 1781 and 29 days later seen again and entered by Charles Messier in his catalogue "of nebulae and star clusters". It was one of the first spiral galaxies to be discovered, and was listed as one of fourteen spiral nebulae by Lord William Parsons of Rosse in 1850. NGC 4323 and NGC 4328 are satellite galaxies of M100; the former is connected with it by a bridge of luminous matter.

Messier 84 or M84, also known as NGC 4374, is a giant elliptical or lenticular galaxy in the constellation Virgo. Charles Messier discovered the object in 1781 in a systematic search for "nebulous objects" in the night sky. It is the 84th object in the Messier Catalogue and in the heavily populated core of the Virgo Cluster of galaxies, part of the local supercluster.

<span class="mw-page-title-main">NGC 2748</span> Galaxy in the constellation Camelopardalis

NGC 2748 is a spiral galaxy in the northern circumpolar constellation of Camelopardalis, located at a distance of 61.3 megalight-years from the Milky Way. It was discovered September 2, 1828 by John Herschel. The morphological classification of SAbc indicates this is an unbarred spiral with moderate to loosely-wound spiral arms. It is a disk-like peculiar galaxy with a stellar shell that is rotating about the main galactic axis. This shell was most likely formed through the capture and disruption of a dwarf companion. The galactic nucleus likely contains a supermassive black hole with a mass of 4.4+3.5
−3.6×107 M☉, or 44 million times the mass of the Sun.
