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]

Supernovae

Three supernovae have been observed in NGC 1578:

  • SN 2013fz (Type Ia, mag. 15.1) was discovered by Stuart Parker as part of the Backyard Observatory Supernova Search (BOSS) on 2 November 2013.[4][5]
  • SN 2014cd (Type Ia, mag. 15.9) was discovered by Stuart Parker as part of the Backyard Observatory Supernova Search (BOSS) on 9 August 2014.[6][7]
  • SN 2025absv (Type II-P, mag. 18.816) was discovered by ATLAS on 23 October 2025.[8]
