Detailed explanation-2: -Galaxies that don’t have a spiral or elliptical shape are often called irregular galaxies. NGC 1427A here is an irregular galaxy, and if you look closely, you can see a spiral galaxy off to the left in the distance. Image by NASA, ESA, and The Hubble Heritage Team (STScI/AURA).
