NGC 3936
barred spiral galaxy in the constellation Hydra
NGC 3936 is a barred spiral galaxy in the constellation of Hydra. Its velocity with respect to the cosmic microwave background is 2,357 ± 24 km/s, which corresponds to a Hubble distance of 34.76 ± 2.46 Mpc (~113 million light-years). It was discovered by British astronomer John Herschel on 24 March 1835.
As of July 2024, 26 non-redshift measurements give a distance of 20.912 ± 2.969 Mpc (~68.2 million light-years), which is well outside the Hubble distance values. But, since this galaxy is relatively close to the Local Group, it is very likely that this value is closer to the true distance to NGC 3936.
NGC 3936 Group
NGC 3936 is the largest of a small group of four galaxies named after it. The other three galaxies in the NGC 3936 group (also known as LGG 253) are NGC 3885, ESO 440–4, and ESO 440–11.
Supernova
One supernova has been observed in NGC 3936: SN 2024phv (Type II, mag. 17.3523) was discovered by the Distance Less Than 40 Mpc Survey (DLT40) on 10 July 2024.
This brief starts where responsible research should: with the source description of “NGC 3936” as barred spiral galaxy in the constellation Hydra. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as barred spiral galaxy in the constellation Hydra. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 3, 2026. The linked authority identifier is Q1107207. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1835 and 2024.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
