NGC 3545B is an elliptical galaxy in the constellation Ursa Major. The object is close to NGC 3545. [3]
Messier 102 is a galaxy listed in the Messier Catalogue that cannot be unambiguously identified. Its original discoverer Pierre Méchain retracted his discovery two years after publication and said that it was a duplicate observation of Messier 101. Later historical evidence favors that M102 is actually the galaxy NGC 5866, although other galaxies have been suggested as possible identities. The National Aeronautics and Space Administration (NASA) considers it to be the same as NGC 5866.
NGC 1, also occasionally referred to as GC 1, UGC 57, PGC 564 or Holm 2a is an intermediate spiral galaxy of the morphological type Sbc, located approximately 210 to 215 million light-years from the Solar System in the constellation Pegasus. It was discovered on 30 September 1861 by Heinrich d'Arrest.
NGC 4639 is a barred spiral galaxy located in the equatorial constellation of Virgo. It was discovered by German-born astronomer William Herschel on April 12, 1784. John L. E. Dreyer described it as "pretty bright, small, extended, mottled but not resolved, 12th magnitude star 1 arcmin to southeast". This is a relatively nearby galaxy, lying approximately 72 million light-years away from the Milky Way. It is a companion to NGC 4654, and the two appear to have interacted roughly 500 million years ago. NGC 4639 is a member of the Virgo Cluster.
Arp 87 is a pair of interacting galaxies, NGC 3808A and NGC 3808B. They are situated in the Leo constellation. NGC 3808A, the brighter, is a peculiar spiral galaxy, while NGC 3808B is an irregular galaxy.
NGC 27 is a spiral galaxy located in the constellation Andromeda. It was discovered on 3 August 1884 by Lewis Swift. It forms a galaxy pair with the nearby UGC 95.
NGC 6052 is a pair of galaxies in the constellation of Hercules. It was discovered on 11 June 1784 by William Herschel. It was described as "faint, pretty large, irregularly round" by John Louis Emil Dreyer, the compiler of the New General Catalogue.
NGC 521, also occasionally referred to as PGC 5190 or UGC 962, is a spiral galaxy located approximately 224 million light-years from the Solar System in the constellation Cetus. It was discovered on 8 October 1785 by astronomer William Herschel.
NGC 5575 is a lenticular galaxy in the constellation Virgo. The object was discovered on May 8, 1864 by the German astronomer Albert Marth.
NGC 6975, also known as NGC 6976, is a spiral galaxy in the constellation Aquarius. The object was discovered on 12 July 1864 by the German astronomer Albert Marth.
NGC 3402, also known as NGC 3411, is an elliptical galaxy in the constellation Hydra. The object was discovered on March 25, 1786 by German-British astronomer William Herschel. NGC 3402 is the largest galaxy in the eponymous NGC 3402 cluster.
NGC 7041B is a spiral or lenticular galaxy in the constellation Indus. The object was discovered on 7 July 1834 by the British astronomer John Herschel.
NGC 3313 is a large barred spiral galaxy located about 55 megaparsecs away in the constellation Hydra. It was discovered by astronomer Ormond Stone in 1886 and is an outlying member of the Hydra Cluster.
NGC 527, also occasionally referred to as PGC 5128 or PGC 5141, is a lenticular galaxy located approximately 259 million light-years from the Solar System in the constellation Sculptor. It was discovered on 1 September 1834 by astronomer John Herschel.
NGC 3336 is a barred spiral galaxy located about 190 million light-years away in the constellation Hydra. It was discovered by astronomer John Herschel on March 24, 1835. NGC 3336 is a member of the Hydra Cluster.
NGC 1259 is a lenticular galaxy located about 243 million light-years away in the constellation Perseus. The galaxy was discovered by astronomer Guillaume Bigourdan on October 21, 1884 and is a member of the Perseus Cluster.
NGC 1268 is a spiral galaxy located about 140 million light-years away in the constellation Perseus. It was discovered by astronomer Heinrich d'Arrest on February 14, 1863. NGC 1268 is a member of the Perseus Cluster and appears to show signs of distortion in the form of bridges. These features may be the result of a strong interaction with NGC 1267.
NGC 1282 is an elliptical galaxy located about 230 million light-years away in the constellation Perseus. It was discovered by astronomer Guillaume Bigourdan on October 23, 1884. NGC 1282 is a member of the Perseus Cluster.
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 528 is a lenticular galaxy located in the constellation Andromeda. It is located an estimated 70 million parsecs from the Milky Way. The object was discovered on 22 August 1865 by the German-Danish astronomer Heinrich Ludwig d'Arrest.
NGC 541 is a lenticular galaxy located in the constellation Cetus. It is located at a distance of circa 230 million light years from Earth, which, given its apparent dimensions, means that NGC 541 is about 130,000 light years across. It was discovered by Heinrich d'Arrest on October 30, 1864. It is a member of the Abell 194 galaxy cluster and is included in the Atlas of Peculiar Galaxies in the category galaxies with nearby fragments. NGC 541 is a radio galaxy of Fanaroff-Riley class I, also known as 3C 40A.
