The galaxies are vast collections of stars and gas. Our galaxy (the one we are in) is called the Milky Way. It contains some 200 to 400 billion stars, and is a barred spiral galaxy that stretches out one hundred thousand (100,000) light years. At the center the core is some 10,000 light years thick, but out by us its just 3000 light years wide. (This last line comes from "The Galaxy Song.")
There are roughly one hundred billion (100,000,000,000) galaxies in our universe.

What the difference between universe and galaxies?
A universe is a very big realm of darkness with galaxies in it. and there are billions of galaxies in the universe! One of those galaxies is our solar system, and in that solar system is our planet.

Is there an infinite number of galaxies in the universe?
Yes, there is believed to be an infinite number of galaxies in the universe.
How does the density of galaxies change as the universe expands?
As the universe expands, the density of galaxies decreases. This is because the space between galaxies increases as the universe expands, leading to a lower concentration of galaxies in a given volume of space.
What is the estimated number of dwarf galaxies since there are 100 billion galaxies in the universe?

What galaxies in the universe are irregular galaxies?
Irregular ones!
Is the galaxy the universe?
The galaxy, the one we are in, we call the Milky Way. It is one of billions of galaxies. These galaxies and everything else make up the universe. Compared to the universe galaxies are small fry.
What is the estimated number of satellite galaxies since there are 100 billion galaxies in the universe?
The estimated number of satellite galaxies, given that there are 100 billion galaxies in the universe, is 170 billion.
