A spiral galaxy is a type of galaxy characterized by a central bulge of old Population II stars surrounded by a rotating disc of younger Population I stars. A spiral galaxy maintains its spiral arms due to density wave theory.

Spiral galaxies

Below is a list of notable spiral galaxies with their own articles. The classification column refers to the galaxy morphological classification used by astronomers to describe galaxy structure.
