NGC 1398 is an isolated barred spiral galaxy exhibiting a double ring structure. It is located 65 million light years from the Earth, in the constellation of Fornax. [2] [3] The galaxy, with a diameter of 135,000 light years, is bigger than the Milky Way. Over 100 billion stars are in the galaxy. [4] It was first discovered by Friedrich Winnecke of Karlsruhe, Germany, on 17 December 1868, while he was searching for comets. [5]
One supernova has been observed in NGC 1398: SN 1996N (type Ib/c, mag. 16). [6]
Fornax is a constellation in the southern celestial hemisphere, partly ringed by the celestial river Eridanus. Its name is Latin for furnace. It was named by French astronomer Nicolas Louis de Lacaille in 1756. Fornax is one of the 88 modern constellations.
NGC 1365, also known as the Great Barred Spiral Galaxy, is a double-barred spiral galaxy about 56 million light-years away in the constellation Fornax.
NGC 1300 is a barred spiral galaxy located about 61 million light-years away in the constellation Eridanus. The galaxy is about 110,000 light-years across. It is a member of the Eridanus Cluster, a cluster of 200 galaxies. It was discovered by John Herschel in 1835.
NGC 1532, also known as Haley's Coronet, is an edge-on barred spiral galaxy located approximately 50 million light-years from the Solar System in the constellation Eridanus. The galaxy was discovered by James Dunlop on 29 October 1826.
NGC 1097 is a barred spiral galaxy about 45 million light years away in the constellation Fornax. It was discovered by William Herschel on 9 October 1790. It is a severely interacting galaxy with obvious tidal debris and distortions caused by interaction with the companion galaxy NGC 1097A.
NGC 1350 is a spiral galaxy located 87 million light years away in the southern constellation Fornax.
NGC 6786 is an interacting spiral galaxy 350 million light years from the Earth, in the constellation of Draco. NGC 6786 is currently interacting with LEDA 62867, and, being the larger galaxy, it is likely that NGC 6786 will absorb LEDA 62867 in the future. Both galaxies appear to be undergoing a starburst, a phenomenon commonly seen among interacting and merging galaxies.
NGC 986 is a barred spiral galaxy in the southern constellation of Fornax, located about 76 million light-years away. It was discovered on August 5, 1826 by the Scottish astronomer James Dunlop, who described it as a "faint nebula, of an irregular round figure". The galaxy has an angular size of 3′.8 × 1′.9 with a visual magnitude of 10.9. It belongs to the Fornax Cluster of galaxies. This galaxy has a nearby companion, NGC 986A, at an angular separation of 17′, corresponding to a projected separation of 110 kpc. The two appear unconnected.
NGC 480 is a spiral galaxy located about 546 million light-years away from Earth in the constellation Cetus. NGC 480 was discovered by American astronomer Francis Leavenworth In 1886.
NGC 4454 is a barred spiral galaxy located about 123 million light-years away in the constellation of Virgo. NGC 4454 was discovered by astronomer William Herschel on April 17, 1784.
NGC 493, also occasionally referred to as PGC 4979 or GC 281, is a barred spiral galaxy in the constellation Cetus. It is located approximately 90 million light-years from Earth and was discovered on December 20, 1786 by astronomer William Herschel. It was later also observed by his son, John Herschel. John Dreyer, creator of the New General Catalogue, described the galaxy as "very faint, large, much extended 60°" with "a little brighter middle".
NGC 494, also occasionally referred to as PGC 5035 or GC 282, is a barred spiral galaxy in the constellation Pisces. It is located approximately 227 million light-years from Earth and was discovered on 22 November 1827 by astronomer John Herschel. John Dreyer, creator of the New General Catalogue, described the galaxy as "very faint, pretty large, extended, 3 faint stars to south".
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 1255 is a barred spiral galaxy approximately 69 million light-years away from Earth in the constellation of Fornax.
NGC 1436 is a barred spiral galaxy approximately 58 million light-years away from Earth in the constellation of Eridanus. It is a member of the Fornax I cluster.
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 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 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 5395 is an interacting spiral galaxy located at a distance of 160 million light years, but receding away from the Earth at 3511 kilometers per second, in the constellation Canes Venatici. It was discovered by William Herschel on May 16, 1787. NGC 5395 and NGC 5394 are included in the Atlas of Peculiar Galaxies as Arp 84 in the category "Spiral galaxies with large high surface brightness companions".
NGC 1317 is a barred spiral galaxy in the constellation Fornax, in the Fornax cluster. It was discovered by Julius Schmidt on January 19, 1865. It appears to be interacting with the much larger NGC 1316, but uncertainty in distance estimates and scales of tidal distortions make this uncertain. It is a member of the NGC 1316 subgroup, part of the Fornax Cluster. Its size is 2.8' x 2.4' which, at the average distance, gives a diameter of 55,000 light-years.
