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".
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.
It's a galaxy
they all are in space?
