NGC 1578 is a spiral galaxy in the constellation of Dorado. Its velocity with respect to the cosmic microwave background is 6,166±26 km/s, which corresponds to a Hubble distance of 296.6 ± 20.8 Mly (90.94 ± 6.39 Mpc).[1] It was discovered by British astronomer John Herschel on 27 December 1834.[2]
NGC 1578 is an active galactic nucleus candidate, i.e. it has a compact region at the center of a galaxy that emits a significant amount of energy across the electromagnetic spectrum, with characteristics indicating that this luminosity is not produced by the stars.[3]
