NGC 7124 is a large spiral galaxy in the constellation of Indus. Its velocity with respect to the cosmic microwave background is 4988 ± 15 km/s, which corresponds to a Hubble distance of 240.0 ± 16.8 Mly (73.57 ± 5.16 Mpc).[1] However, nine non-redshift measurements give a much closer distance of 191.56 ± 4.26 Mly (58.733 ± 1.306 Mpc).[2] It was discovered by British astronomer John Herschel on 8 July 1834.[3]
NGC 7124 is classified as a LINER galaxy, i.e. it has a type of nucleus that is defined by its spectral line emission which has weakly ionized or neutral atoms, while the spectral line emission from strongly ionized atoms is relatively weak.[1]
One supernova has been observed in NGC 7124: SN 2023pwl (type Ia, mag 16.7) was discovered by ATLAS on 19 August 2023.[4]
