NGC 70
spiral galaxy in the constellation Andromeda
NGC 70 is a spiral galaxy located in the constellation Andromeda. It was discovered on October 7, 1855, by R. J. Mitchell and was observed on December 19, 1897, by Guillaume Bigourdan from France who described it as "extremely faint, very small, round, between 2 faint stars".
NGC 70 hosts a Seyfert Type II Active galactic nucleus (AGN).
NGC 70 is a member of a compact group of seven or eight galaxies, sometimes called the NGC 70 Group or the VV 166 Group.
The group comprises three relatively bright galaxies: 70, 71 and 72 in the NGC catalog, and four fainter galaxies. NGC 68 appears to be a group member, but its discrepant radial velocity and lack of tidal distortion suggest that it may be an unrelated galaxy along the group's line of sight. In photographs, the NGC 70 group resembles the much more famous Stephan's Quintet group, and it is a popular target for amateur astrophotographers.
The public source identifies “NGC 70” as spiral galaxy in the constellation Andromeda. This brief keeps that definition visible, then builds a research path around spiral, galaxy and constellation.
Why this record matters
A short description can identify a subject without explaining its stakes. For “NGC 70”, the useful work is to connect “spiral galaxy in the constellation Andromeda” to the records capable of establishing context and consequence.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 3, 2026. The linked authority identifier is Q515295. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1855 and 1897.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
