NGC 753 is a spiral galaxy[2] located 220 million light-years away[3] 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 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. This open structure of the arms may be due to the influence of NGC 759 which is a close companion of NGC 753 that lies 0.44Mpc away.

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[20] and AT 2018ddf which was discovered on July 5, 2018.[21] [22] Both supernovae were of unknown types.
