NGC 3717 is a spiral galaxy located in the constellation of Hydra at an approximate distance of 81.43 million light years. NGC 3717 was discovered in 1834 by Sir John Herschel. [1]
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.
NGC 1232 is an intermediate spiral galaxy about 60 million light-years away in the constellation Eridanus. It was discovered by German-British astronomer William Herschel on 20 October 1784.
NGC 4567 and NGC 4568 are a set of unbarred spiral galaxies about 60 million light-years away in the constellation Virgo. They were both discovered by William Herschel in 1784. They are part of the Virgo Cluster of galaxies.
NGC 37 is a lenticular galaxy located in the Phoenix constellation. It is approximately 42 kiloparsecs in diameter and about 12.9 billion years old.
Arp 272 is a pair of interacting galaxies consisting of the two spiral galaxies NGC 6050 (left) and IC 1179 (right). Arp 272 lies around 450 million light years from Earth in the constellation of Hercules. The galaxies are part of the Hercules Cluster, which is itself part of the CfA2 Great Wall.
NGC 296 is a low surface brightness unbarred spiral galaxy in the constellation of Pisces. The designation NGC 295 is sometimes mistakenly used for NGC 296.
NGC 4980 is a spiral galaxy in the southern constellation of Hydra. The shape of NGC 4980 appears slightly deformed, something which is often a sign of recent tidal interactions with another galaxy. In this galaxy's case, however, this appears not to be the case as there are no other galaxies in its immediate vicinity.
NGC 1015 is a barred spiral galaxy, at a distance of 118 million light years in the constellation of Cetus.
NGC 5714 is a spiral galaxy located 130 million light-years away in the constellation of Boötes. It was discovered by William Herschel in 1787. This galaxy is about 130 million light-years away.
NGC 2936 is an interacting spiral galaxy located at a distance of 326 million light years, in the constellation Hydra. NGC 2936 is interacting with elliptical galaxy NGC 2937, located just beneath it. They were both discovered by Albert Marth on Mar 3, 1864. To some astronomers, the galaxy looks like a penguin or a porpoise. NGC 2936, NGC 2937, and PGC 1237172 are included in the Atlas of Peculiar Galaxies as Arp 142 in the category "Galaxy triplet".
NGC 6902 is an unbarred spiral galaxy located in the constellation of Sagittarius at an approximate distance of 131.80 Mly. NGC 6902 was discovered in 1836 by John Herschel.
NGC 7773 is a barred spiral galaxy located in the constellation of Pegasus at an approximate distance of 400 million light years. NGC 7773 was discovered on October 9, 1790 by William Herschel.
NGC 4900 is a barred spiral galaxy in the constellation Virgo. It was discovered by William Herschel on April 30, 1786. It is a member of the NGC 4753 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 4781 is a barred spiral galaxy in the constellation Virgo. It was discovered by William Herschel on Mar 25, 1786. It is a member of the NGC 4699 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 755 is an emission line spiral galaxy in the constellation of Cetus. The galaxy's velocity of 1641.2 km/s was used to calculate its distance using the Tully–Fisher relation. Its dark matter halo was found to be core-dominated, in agreement with predictions from the lambda-CDM model of cosmology.
NGC 3749 is a spiral galaxy located in the constellation of Centaurus at an approximate distance of 130.52 million light-years. NGC 3749 was discovered in 1835 by John Herschel.
NGC 3175 is a spiral galaxy located in the far eastern part of the southern constellation of Antlia at an approximate distance of 54 million light-years. NGC 3175 was discovered on March 30, 1835 by English astronomer John Herschel, whose notes described it as, "considerably bright, large, much extended NE-SW, very gradually little brighter middle". This galaxy is the namesake of the NGC 3175 group of galaxies, which includes the spiral galaxy NGC 3137.
NGC 4455 is a spiral galaxy located in the constellation of Coma Berenices at an approximate distance of 28.06 Mly. NGC 4455 was discovered in 1785 by William Herschel.
NGC 5533 is an unbarred spiral galaxy in the constellation Boötes. It was discovered by the astronomer William Herschel on May 1, 1785. It has a regular structure, with one tightly wound spiral; its disk is inclined about 53 degrees towards the line of sight.
