NGC 508, also occasionally referred to as PGC 5099 or UGC 939, is an elliptical galaxy in the constellation Pisces. [2] It is located approximately 247 million light-years from the Solar System [4] and was discovered on 12 September 1784 by British astronomer William Herschel. [5] [6]
Herschel discovered NGC 508 along with NGC 507 and described the objects as "Two. Both eF, S, but unequal.". His observed position was catalogued and is accurate. [6] John Louis Emil Dreyer, creator of the New General Catalogue, described the galaxy as "very faint, small, northern of two", with the other object being NGC 507. [5]
The galaxy has an apparent size of 1.1 × 1.1 arcmins and a recessional velocity of 5525 kilometers per second. It is thought to be a group member with NGC 507, but as there is no evidence of interaction between the objects, the two are not necessarily a physical pair. Although NGC 508 is usually treated as part of Arp 229, the description of the Arp-galaxy only applies to the larger NGC 507. Therefore, the term Arp 229 should only be used as an alternative designation for NGC 507. [5]
NGC 57 is an elliptical galaxy in the constellation Pisces. It was discovered on 8 October 1784 by astronomer William Herschel.
NGC 462 is an elliptical galaxy located in the Pisces constellation. It was discovered by Albert Marth on 23 October 1864. Dreyer, creator of the New General Catalogue, originally described it as "extremely faint, very small, stellar". The word stellar clearly suggests an initial misidentification of NGC 462 as a star.
NGC 507, also known as Arp 229, CGCG 502-67, MCG 5-4-44, PGC 5098, UGC 938, and V V 207, is a lenticular galaxy in the constellation Pisces. It was described as being "very faint", "pretty large", "round", "brighter in the middle", and "south of NGC 508" by John Dreyer in the New General Catalogue. The two galaxies are a part of the Atlas of Peculiar Galaxies, where NGC 507 is described as "Circular or near circular rings of small density difference."
NGC 485, also commonly referred to as PGC 4921 or GC 270, is a spiral galaxy in the constellation Pisces. It is located approximately 86 million light-years from Earth and was discovered on January 8, 1828 by astronomer William Herschel. It was later also observed by Heinrich d'Arrest and Herman Schultz. When NGC 485 was originally categorized in the New General Catalogue by John Louis Eil Dreyer in 1888, it was incorrectly described as a "considerably faint, pretty large, round, 8th magnitude star 3 1/2 arcmin to southwest".
NGC 495, also occasionally referred to as PGC 5037, UGC 920 or GC 278, is a barred spiral galaxy in the constellation Pisces. It is located approximately 184 million light-years from the Solar System and was discovered on 12 September 1784 by astronomer William Herschel.
NGC 496, also occasionally referred to as PGC 5037, UGC 927 or GC 288, is a spiral galaxy in the constellation Pisces. It is located approximately 250 million light-years from the Solar System and was discovered on 12 September, 1784 by astronomer William Herschel.
NGC 499, also occasionally referred to as PGC 5060, IC 1686 or GC 289, is a lenticular galaxy in the constellation Pisces. It is located approximately 197 million light-years from the Solar System and was discovered on 12 September, 1784 by astronomer William Herschel.
NGC 501, also occasionally referred to as PGC 5082 or GC 284, is an elliptical galaxy in the constellation Pisces. It is located approximately 224 million light-years from the Solar System and was discovered on 28 October 1856 by Irish astronomer R. J. Mitchell.
NGC 502, also occasionally referred to as PGC 5034 or UGC 922, is a lenticular galaxy in the constellation Pisces. It is located approximately 113 million light-years from the Solar System and was discovered on 25 September 1862 by German astronomer Heinrich Louis d'Arrest. When the Morphological Catalogue of Galaxies was published between 1962 and 1974, the identifications of NGC 502 and NGC 505 were reversed. In reality, NGC 502 is equal to MGC +01-04-041 and not MCG +01-04-043 as noted in the catalogue.
NGC 503, also occasionally referred to as PGC 5086 or GC 5169, is an elliptical galaxy in the constellation Pisces. It is located approximately 265 million light-years from the Solar System and was discovered on 13 August 1863 by German astronomer Heinrich Louis d'Arrest.
NGC 504, also occasionally referred to as PGC 5084 or UGC 935, is a lenticular galaxy located approximately 189 million light-years from the Solar System in the constellation Pisces. It was discovered on 22 November 1827 by astronomer John Herschel. The object was listed twice in the General Catalogue, precursor of the New General Catalogue, as both GC 291 and GC 292.
NGC 511, also occasionally referred to as PGC 5103 or UGC 936, is an elliptical galaxy in the constellation Pisces. It is located approximately 499 million light-years from the Solar System and was discovered on 26 October 1876 by French astronomer Édouard Stephan.
NGC 512, also occasionally referred to as PGC 5132 or UGC 944, is a spiral galaxy in the constellation Andromeda. It is located approximately 217 million light-years from the Solar System and was discovered on 17 November 1827 by astronomer John Herschel.
NGC 513, also occasionally referred to as PGC 5174 or UGC 953, is a spiral galaxy in the constellation Andromeda. It is located approximately 262 million light-years from the Solar System and was discovered on 13 September 1784 by astronomer William Herschel.
NGC 515, also occasionally referred to as PGC 5201 or UGC 956, is a lenticular galaxy located approximately 228 million light-years from the Solar System in the constellation Pisces. It was discovered on 13 September 1784 by astronomer William Herschel.
NGC 517, also occasionally referred to as PGC 5214 or UGC 960, is a lenticular galaxy located approximately 188 million light-years from the Solar System in the constellation Pisces. It was discovered on 13 September 1784 by astronomer William Herschel.
NGC 519, also occasionally referred to as PGC 5182 is an elliptical galaxy located approximately 242 million light-years from the Solar System in the constellation Cetus. It was discovered on 20 November 1886 by astronomer Lewis Swift.
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 525, also occasionally referred to as PGC 5232 or UGC 972 is a lenticular galaxy located approximately 95.6 million light-years from the Solar System in the constellation Pisces. It was discovered on 25 September 1862 by astronomer Heinrich d'Arrest.
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.
