NGC 4088 is a grand design spiral galaxy.[5] This means that the spiral arms in the galaxy's disk are sharply defined. In visible light, one of the spiral arms appears to have a disconnected segment. Halton Arp included this galaxy in the Atlas of Peculiar Galaxies as one of several examples where this phenomenon occurs.[6]

NGC 4088 and NGC 4085 are members of the M109 Group, a group of galaxies located in the constellation Ursa Major. This large group contains between 41 and 58 galaxies, including the spiral galaxy M109.[7][8][9]

Supernova 2009dd

On April 13, 2009, SN 2009dd was discovered in NGC 4088.[10] At apparent magnitude 13.8,[10] it became the third-brightest supernova of 2009.[11] In 1991 there was SN1991G.

gollark: Like "trusted computing".
gollark: It's probably some thing which aims to take control away from users by having a magic opaque chip you can't control do things.
gollark: > I thought it was going to break the entire filesystem and I'd have to reinstall everythingYou probably could just mount it from linux?
gollark: MacOS thing.
gollark: Look into "fbterm"?
