there are 3 types of galaxies. 1.spiral 2.elliptical 3.irregular
the main galaxy in our universe would be a spiral galaxy
Spiral
All galaxies appear to be unique; they are all equally uncommon. Except ours; the Milky Way is the only galaxy to have US in it. Edit : Galaxies are classified into various types. The most uncommon type is known as "Irregular".
The most common types of galaxies, particularly spiral galaxies, often appear bluish due to the presence of young, hot stars that emit blue light. In contrast, elliptical galaxies tend to look more reddish, as they are composed mainly of older stars that emit light in the red spectrum. Overall, the color of a galaxy can indicate its star formation activity and age, with blue galaxies being more active and red galaxies being older and more quiescent.
Galaxies are made mostly of empty space. The most common elements however are hydrogen and helium.

The two most common elements found in nebulas are hydrogen and helium. These elements are the building blocks of stars and galaxies, and are formed during the process of stellar nucleosynthesis.
It is currently believed that most, if not all, galaxies contain supermassive black holes at their centers. These black holes can vary in size, with some being relatively small and inactive. However, the presence of supermassive black holes in galaxies is a common feature in the universe.
I think the least common is elliptical or irregular..
All galaxies are massive clusters of stars scattered across the universe. Many galaxies take the same form, for instance, spiral and elliptical galaxies. Some galaxies also have a black hole in their center.
By virtue of their name, dwarf galaxies are smaller. Most galaxies are dwarf galaxies.
Elliptical galaxies are large blob shaped galaxies that most galaxies will eventually look like. Elliptical galaxies are what happens when two or more large galaxies collide and coalesce.
