Physicists and Astronomers

Branches of Astronomy: Astronomers can be classified as either observational or theoretical. Astronomy is also made up of subfields based on the objects being studied. These include Planetary Astronomy, Stellar Astronomy, Solar Astronomy, Galactic Astronomy, and Cosmology, the study of the universe.
