A galaxy is a combination of gas, dust and numerous stars, whose unity is ensured by gravity.
We will see galaxies of different shapes and at different stages of evolution. Gas and dust are the main materials for the formation of a new star.
Spiral galaxies are among the brightest objects in the universe, elliptical galaxies are statistically older stars with less gas and dust, and irregular galaxies are the smallest galaxies in terms of size.
