Galaxy NGC 1090 is a barred spiral galaxy

Barred spiral galaxy

A barred spiral galaxy is a spiral galaxy with a central bar-shaped structure composed of stars. Bars are found in approximately two-thirds of all spiral galaxies...

 with a pseudo inner ring. The disc has a very low surface brightness.

This galaxy has been the site of two known supernovae (in 1962 and 1971).

NGC 1090 is not part of a galaxy group, even though it appears close to NGC 1087

NGC 1087

NGC 1087 is an intermediate spiral galaxy in Cetus. The central bar/core is very small with many irregular features in the surrounding disk of material. With the many strange features of NGC 1087, its true nature is still uncertain. It has an extremely small nucleus and a very short stellar bar....

NGC 1055

NGC 1055 is an edge-on spiral galaxy located in the constellation Cetus that has a prominent nuclear bulge crossed by a wide, knotty, dark lane of dust and gas. The spiral arm structure appears to be elevated above the galaxy's plane and obscures the upper half of the bulge...
