NGC 677 is an elliptical galaxy located in the constellation Aries. It was discovered on September 25, 1886, by the astronomer Lewis A. Swift. [5] It is located about 200 million light-years (70 megaparsecs) from Earth [3] at the center of a rich galaxy cluster. [6] It has a LINER nucleus. [6]
According to A.M. Garcia, NGC 677 is a member of the NGC 673 Group (also known as LGG 31). This group contains at least 17 galaxies, including IC 156, IC 162, NGC 665, NGC 673, NGC 683, and 11 galaxies from the UGC catalogue. [7]
NGC 3344 is a relatively isolated barred spiral galaxy around half the size of the Milky Way located 22.5 million light years away in the constellation Leo Minor. This galaxy belongs to the group known as the Leo spur, which is a branch of the Virgo Supercluster. NGC 3344 has the morphological classification (R)SAB(r)bc, which indicates it is a weakly barred spiral galaxy that exhibits rings and moderate to loosely wound spiral arms. There is both an inner and outer ring, with the prominent arms radiating outward from the inner ring and the slightly elliptical bar being situated inside. At the center of the bar is an HII nucleus with an angular diameter of about 3″. NGC 3344 hosted supernova SN 2012fh, which was shown to likely be a Type Ib or Type Ic.
NGC 5614 is an unbarred spiral galaxy in the constellation Boötes. It is the primary member of the Arp 178 triplet of interacting galaxies with NGC 5613 and NGC 5615.
NGC 3281 is a large unbarred spiral galaxy in the southern constellation of Antlia, located at a distance of 144.7 megalight-years from the Milky Way. The galaxy is inclined by an angle of 64° to the line-of-sight from the Earth, with the major axis aligned with a position angle of 137°. It is a luminous infrared galaxy and a type II Seyfert galaxy. NGC 3281 is a member of the Antlia Cluster, which belongs to the Hydra–Centaurus Supercluster.
NGC 5030 is a barred spiral galaxy in the constellation Virgo. The object was discovered on 17 March 1881 by the American astronomer Edward Singleton Holden.
NGC 1683 is a spiral galaxy in the constellation Orion. The object was discovered in 1850 by the Irish astronomer William Parsons.
NGC 741, also known as PGC 7252, is a formerly active radio galaxy in the constellation of Pisces. Located 74.13 Mpc away, NGC 741 is part of a group of galaxies including NGC 742 and PGC 7250. NGC 741 and NGC 742 recently collided, although the disruption was minor. Radio filaments have been found connecting NGC 741 to NGC 742, and due to the bent structure of the radio filaments, NGC 741 is estimated to be moving at 1400 km/s with respect to its local group, suggesting that ram-pressure stripping was created as a product of the former merger.
NGC 1326 is a lenticular galaxy in the constellation Fornax, 63 million light-years away. It was discovered by English astronomer John Herschel on 29 November 1837. It is a member of the Fornax Cluster, an NGC 1316 subgroup and has a diameter of 70 000 light-years.
NGC 950 is a barred spiral galaxy in the constellation Cetus. It is approximately 205 million light-years away from the Solar System and has a diameter of about 85,000 light-years. The object was discovered in 1886 by American astronomer and mathematician Ormond Stone.
NGC 990 is an elliptical galaxy located in the constellation Aries about 153 million light-years from the Milky Way. It was discovered by the German - British astronomer William Herschel in 1786.
NGC 670 is a lenticular galaxy located in the Triangulum constellation about 165 million light years from the Milky Way. It was discovered by the German-British astronomer William Herschel in 1786.
NGC 790 is a lenticular galaxy in the constellation Cetus. It is estimated to be 233 million light-years from the Milky Way and has a diameter of approximately 90,000 light years. NGC 790 was discovered on September 10, 1785 by the German-British astronomer William Herschel.
NGC 904 is an elliptical galaxy in the constellation Aries. It is estimated to be 244 million light years from the Milky Way and has a diameter of approximately 85,000 ly. NGC 904 was discovered on 13 December 1884 by the astronomer Edouard Stephan.
NGC 906 is a barred spiral galaxy in the constellation Andromeda in the northern sky. It is estimated to be 215 million light years from the Milky Way and has a diameter of approximately 110,000 ly. NGC 906 was discovered on October 30, 1878 by astronomer Édouard Stephan.
NGC 804 is a lenticular galaxy located in the Triangulum constellation about 231 million light-years from the Milky Way. It was discovered by the American astronomer Lewis Swift in 1885. This galaxy was also observed by the French astronomer Guillaume Bigourdan on December 24, 1897, and it has been added to the Index Catalogue under the symbol IC 1773.
NGC 996 is an elliptical galaxy of the Hubble type E0 in the constellation Andromeda. It is estimated to be 210 million light years from the Milky Way and has a diameter of approximately 75,000 ly. The supernova SN 1996bq occurred in this galaxy. NGC 996 was discovered on December 7, 1871 by astronomer Édouard Stephan.
NGC 531 is a barred spiral galaxy in the constellation Andromeda with a visual magnitude of 10.51. It is a distance of 65.7 Mpc from the Sun. It is a member of the Hickson Compact Group HCG 10, and is interacting with the other members of the group.
