Galaxy Formation
The study of galaxy formation and evolution is concerned with the processes that formed a heterogeneous universe from a homogeneous beginning, the formation of the first galaxies, the way galaxies change overtime, and the processes that have generated the variety of structures observed in nearby galaxies. There are three different types of galaxies: spiral, elliptical, and irregular.

There are three different types of galaxies: spiral, elliptical, and irregular.
Spiral galaxies
- A spiral galaxy is a galaxy in which the stars and gas clouds are concentrated mainly in one or more spiral arms.
Elliptical galaxy
- An elliptical galaxy is a type of galaxy having an approximately ellipsoidal shape and a smooth, nearly featureless brightness profile. Unlike flat spiral galaxies with organization and structure, they are more three-dimensional, without much structure, and their stars are in somewhat random orbits around the center.
Irregular Galaxy
- Having a lot of gas and dust means that these galaxies have a lot of star formation going on within them. This can make them very bright. The Large and Small Magellanic Clouds are examples of irregular galaxies. They are two small galaxies which orbit around our own Milky Way Galaxy.
