Astronomers - Main Astronomers Astronomers study the solar system, stars, and galaxies. They use principles of math and physics to answer questions about the nature of the universe.
Astronomy is a subfield of physics.
Astronomers use the principles of physics and math to learn about the nature of the universe. Astronomers plan projects, make observations, study results, and figure out theories. They study the physical characteristics, origin, development, distribution, and motion of the sun, planets, stars, comets, and other bodies in space. They use math and physics to solve problems in navigation and space flight. Most do research, teach, or do both.
