NGC 953 (also PGC 9586, UGC 1991, MCG 5-7-1, GWT GWT 504 104 or 505.1) is an elliptical galaxy in the constellation Triangulum. It has an apparent magnitude of 14.5. It was discovered by the German astronomer Heinrich Louis d'Arrest on September 26, 1865.
NGC 2 is a spiral galaxy in the constellation Pegasus, discovered by Lawrence Parsons, 4th Earl of Rosse on 20 August 1873, and was described as "very faint, small, south of NGC 1." It lies slightly to the south of NGC 1. It is a faint spiral galaxy of apparent magnitude 14.2.
NGC 3184, the Little Pinwheel Galaxy, is a spiral galaxy approximately 40 million light-years away in the constellation Ursa Major. It has two HII regions named NGC 3180 and NGC 3181.
NGC 1512 is a barred spiral galaxy approximately 38 million light-years away from Earth in the constellation Horologium. The galaxy displays a double ring structure, with a (nuclear) ring around the galactic nucleus and an (inner) further out in the main disk. The galaxy hosts an extended UV disc with at least 200 clusters with recent star formation activity. NGC 1512 is a member of the Dorado Group.
NGC 3877 is a type Sc spiral galaxy that was discovered by William Herschel on February 5, 1788. It is located below the magnitude 3.7 star Chi Ursae Majoris in Ursa Major.
NGC 6744 is an intermediate spiral galaxy about 30 million light-years away in the constellation Pavo (Peacock). It is considered as a Milky Way mimic in the immediate vicinity, displaying flocculent (fluffy) arms and an elongated core. It also has at least one distorted companion galaxy superficially similar to one of the Magellanic Clouds. It was discovered from Parramatta in Australia by Scottish astronomer James Dunlop on 30 June 1826.
The Atlas of Peculiar Galaxies is a catalog of peculiar galaxies produced by Halton Arp in 1966. A total of 338 galaxies are presented in the atlas, which was originally published in 1966 by the California Institute of Technology. The primary goal of the catalog was to present photographs of examples of the different kinds of peculiar structures found among galaxies.
NGC 5090 and NGC 5091 are a set of galaxies approximately 160 million light-years away in the constellation Centaurus. They are in the process of colliding and merging with some evidence of tidal disruption of NGC 5091.
NGC 4976 is a peculiar elliptical galaxy in the constellation Centaurus. It was detected with a 5" telescope working at 20x magnification by comet hunter Jack Bennett.
NGC 5986 is a globular cluster of stars in the southern constellation of Lupus, located at a distance of approximately 34 kilolight-years from the Sun. It was discovered by Scottish astronomer James Dunlop on May 10, 1826. John L. E. Dreyer described it as, "a remarkable object, a globular cluster, very bright, large, round, very gradually brighter middle, stars of 13th to 15th magnitude". Its prograde–retrograde orbit through the Milky Way galaxy is considered irregular and highly eccentric. It has a mean heliocentric radial velocity of +100 km/s. The galacto-centric distance is 17 kly (5.2 kpc), which puts it in the galaxy's inner halo.
NGC 14 is an irregular galaxy in the Pegasus constellation. It was included in Halton Arp's Atlas of Peculiar Galaxies, under the section "Galaxies with the appearance of fission," since the irregular appearance of this galaxy causes it to look like it is coming apart. It was discovered on September the 18th 1786 by William Herschel.
NGC 36 is a barred spiral galaxy in the constellation Pisces. It is located about 221 million light-years away. It was discovered in October 25, 1785 by the astronomer William Herschel.
Arp 271 is a pair of similarly sized interacting spiral galaxies, NGC 5426 and NGC 5427, in the constellation of Virgo. It is not certain whether the galaxies are going to eventually collide or not. They will continue interacting for tens of millions of years, creating new stars as a result of the mutual gravitational attraction between the galaxies, a pull seen in the bridge of stars already connecting the two. Located about 130 million light-years away, the Arp 271 pair is about 130,000 light-years across. It was originally discovered in 1785 by William Herschel. It is speculated, that the Milky Way will undergo a similar collision in about five billion years with the neighbouring Andromeda Galaxy, which is currently located about 2.6 million light-years away.
NGC 4697 is an elliptical galaxy some 40 to 50 million light-years away in the constellation Virgo. It is a member of the NGC 4697 Group, a group of galaxies also containing NGC 4731 and several generally much smaller galaxies This group is about 55 million light-years away; it is one of the many Virgo II Groups, which form a southern extension of the Virgo Supercluster of galaxies.
NGC 474 is an elliptical galaxy about 100 million light years distant in the constellation Pisces. This large galaxy is known to possess tidal shells and tidal tails, although their origins remain unclear. One possible explanation is that NGC 474 interacted with a galaxy several billion years ago.
NGC 4527 is a spiral galaxy in the constellation Virgo. It is a member of the M61 Group of galaxies, which is a member of the Virgo II Groups, a series of galaxies and galaxy clusters strung out from the southern edge of the Virgo Supercluster.
NGC 61 is a pair of lenticular galaxies, NGC 61-A and NGC 61-B in the constellation Cetus. Both were discovered on September 10, 1785 by William Herschel.
NGC 67 is an elliptical galaxy located in the constellation Andromeda that was discovered on October 7, 1855, by R. J. Mitchell, who described it as "extremely faint, very small, round". The galaxy belongs to the NGC 68 group, which also contains the galaxies NGC 68, NGC 69, NGC 70, NGC 71, NGC 72, and possibly NGC 74.
NGC 6328 is an intermediate spiral galaxy located in the constellation Ara. It is classified as SAB(s)ab in the galaxy morphological classification scheme and was discovered by the British astronomer John Herschel on 2 May 1835. NGC 6328 is located at about 199 million light years away from Earth.
NGC 148 is a lenticular galaxy located in the constellation Sculptor. It is about 40,000 light years across. It is in a group of three galaxies along with MCG-5-2-16 and IC 1555. It is a Shapley-Ames galaxy.
NGC 655 is a lenticular galaxy located 400 million light-years away in the constellation Cetus. It was discovered in a sky-survey by Ormond Stone on December 12, 1885.
