In general, astronomers study stars, planets and all other phenomena that exist in space. Astronomers wish to learn about the way the universe works, how it came to exist and how it has evolved and how it will continue to evolve.

There are different types of astronomers and each one of them contributes to the study of the universe in different ways.

Observational astronomers: these astronomers observe and study various celestial bodies.

Theoretical astronomers: astronomers cannot document the evolution of celestial bodies, seeing how some of them take more than a century to evolve. So they rely on material collected by observational astronomers. Observational astronomy and theoretical astronomy usually go hand-in-hand. Some observational astronomers collect information, snapshots and pictures and they study them so they can form theories on how the universe and various celestial bodies have come to exist. Hence, the observational astronomy and theoretical astronomy blend together in some ways.

Galactic astronomers: these astronomers study the Milky Way. Though there are several other galaxies in the universe, a galactic astronomer focuses on the Milky Way. The Milky Way is the name of the galaxy that we live in. It contains our solar system and the various planets and 200 billion stars (that can be seen in the night sky) in it. The Milky Way can be seen as,
