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]

Physical characteristics

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]

Supermassive black hole

NGC 753 has a supermassive black hole with an estimated mass of (2.2 ± 0.4) × 107 M☉. [16]

Supernovae

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]
