NGC 753 is a spiral galaxy [3] located 220 million light-years away [2] in the constellation Andromeda. The galaxy was discovered by astronomer by Heinrich d'Arrest on September 16, 1865 [4] and is a member of Abell 262. [5] [6] [7] [8] [9] [10]
NGC 753 has roughly 2-3 times more mass than the Milky Way [5] and is classified as a radio galaxy. [11] [12] [13]
NGC 753 contains two main arms that extend to 180° on either side of the galaxy. [14] [15] From the two main arms, there are three larger and weaker arms that sub-divide into several branches. [14] This open structure of the arms may be due to the influence of NGC 759 which is a close companion of NGC 753 [14] [15] that lies 1.4 Mly (0.44 Mpc ) away. [15]
NGC 753 has a supermassive black hole with an estimated mass of (2.2 ± 0.4) × 107 M☉. [16]
NGC 753 has hosted two supernovae, [17] SN 1954E which was discovered by Fritz Zwicky [18] [19] on September 26, 1954 [18] [19] [17] [20] and AT 2018ddf which was discovered on July 5, 2018. [17] [21] [22] Both supernovae were of unknown types. [17] [19] [21] [20] [22]
NGC 1260 is a spiral or lenticular galaxy in the constellation Perseus. It was discovered by astronomer Guillaume Bigourdan on 19 October 1884. NGC 1260 is a member of the Perseus Cluster and forms a tight pair with the galaxy PGC 12230. In 2006, it was home to the second brightest supernova in the observable universe, supernova SN 2006gy.
NGC 4207 is a spiral galaxy located about 50 million light-years away in the constellation Virgo. The galaxy was discovered by astronomer Heinrich d'Arrest on March 23, 1865. NGC 4207 is a member of the Virgo Cluster.
NGC 3883 is a large low surface brightness spiral galaxy located about 330 million light-years away in the constellation Leo. NGC 3883 has a prominent bulge but does not host an AGN. The galaxy also has flocculent spiral arms in its disk. It was discovered by astronomer William Herschel on April 13, 1785 and is a member of the Leo Cluster.
NGC 4212 is a flocculent spiral galaxy with LINER activity located about 53 million light-years away in the constellation Coma Berenices. The galaxy was discovered by astronomer William Herschel on April 8, 1784, and was listed in the NGC catalog as NGC 4208. He then observed the same galaxy and listed it as NGC 4212. Astronomer John Louis Emil Dreyer later concluded that NGC 4208 was identical to NGC 4212. NGC 4212 is a member of the Virgo Cluster.
NGC 3981 is an unbarred spiral galaxy located 62 million light-years away in the constellation of Crater. It was discovered on February 7, 1785 by William Herschel.
