What Are Irregular Galaxies and How Are Irregular Galaxies Formed?

Galaxies that do not share a common shape fall into the catchall category of irregular galaxies.

Irregular galaxies are uncommon, and they are often chaotic in appearance, with neither a nuclear bulge nor any trace of spiral arm structure.
