Astronomy Major Description

Astronomy Major focuses on the planetary, galactic, and stellar phenomena occurring in outer space. Includes instruction in celestial mechanics, cosmology, stellar physics, galactic evolution, quasars, stellar distribution and motion, interstellar medium, atomic and molecular constituents of astronomical phenomena, planetary science, solar system evolution, and specific methodologies such as optical astronomy, radioastronomy, and theoretical astronomy.

What kind of students major in Astronomy?

Astronomy Major is generally recognized as a sub-field within physics. In order to be successful in this field a student must be very strong in physics, mathematics and the sciences, generally. This calls for a mind that can deal with conceptual frameworks and ideas readily, especially since the objects of study are seldom within reach.
