NGC 2325


NGC 2325 is a elliptical galaxy in the constellation of Canis Major. Its velocity with respect to the cosmic microwave background is, which corresponds to a Hubble distance of. However, 16 non-redshift measurements give a much closer mean distance of. It was discovered by British astronomer John Herschel on 1 February 1837.
NGC 2325 is a radio galaxy, i.e. it has giant regions of radio emission extending well beyond its visible structure. It also has an active galactic nucleus, 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.

Galaxy group

NGC 2325 is a member of a galaxy group known as HDC 421. The group contains at least eight galaxies, including IC 456, ESO 427-22, MCG-05-17-006, MCG-05-17-004, MCG-05-17-008, and two others.

Supernova

One supernova has been observed in NGC 2325:SN 2010ih was discovered by The CHilean Automatic Supernova sEarch on 29 September 2010. A prediscovery image taken on 16 September showed it at magnitude 12.8, making it the brightest supernova of 2010.
