Also question is, what is the most common type of galaxy?

Spiral galaxies are the most common type in the universe. Our Milky Way is a spiral, as is the rather close-by Andromeda Galaxy. Spirals are large rotating disks of stars and nebulae, surrounded by a shell of dark matter. The central bright region at the core of a galaxy is called the “galactic bulge”.

Similarly, why are there different types of galaxies? Explanation: The galaxies that have been undisturbed for billions of years are likely to form spiral, disk shaped galaxies. Smaller galaxies gravitationally attract each other and merge into an elliptical shape.

In this manner, what are the 3 different types of galaxies?

Astronomers group galaxies by shape, and although there are many different types of galaxies, most fall into one of three categories: spiral, elliptical or irregular.

What are the 2 types of spiral galaxies?

Spiral galaxies are classified into two groups, ordinary and barred. The ordinary group is designated by S or SA, and the barred group by SB.
