All of them have stars and space dust for sure.
they all are in space?
I think the least common is elliptical or irregular..
there are as many galaxies as their is grains of sand all over earth and mars so it really does not matter but the answer:spiral but the least common is oval
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.
In theory, all galaxies originate from the Big Bang, which is the name that describes the explosion that propelled all matter into the cosmos. All galaxies are moving. All galaxies produce energy like light and gravity. Think of galaxies like you would human beings. Although very different in some ways, they are mostly the same.
For starters, if there were no separation between two (or more) galaxies, it would be considered a single galaxies, not two or more. The reason matter is clumped together into galaxies at all (with separations in between) is because of gravity - gravity tends to do that, i.e., to clump things together.
Yes, all galaxies have gravity. Gravity is a fundamental force that exists everywhere in the universe, including within and between galaxies. It is responsible for holding galaxies together, as well as determining their structure and motion.
The collection of all galaxies and the space between them is known as the universe. The universe is vast and contains everything that exists, including stars, planets, and dark matter.
There's nothing between the galaxies. It's just other galaxies that float around the universe.
Over time - billions of years - galaxies will merge with other galaxies. In about 3 billion years, the Andromeda galaxy will merge with our own galaxy, the Milky Way.However, the separation between galaxies is so great, that not all galaxies will merge unless the fundamental issue of the amount of mass in the Universe is determined.If we live in a "contracting universe" then eventually all galaxies will merge.

The space in between galaxies is far larger than the galaxies themselves.
