ASTR 210 is a course on modern astronomy and astrophysics for the student with some background in science. The course presents and discusses the physical laws responsible for a variety of astronomical and astrophysical phenomena. Laboratory exercises emphasize the scientific techniques of astronomy and other sciences.

ASTR 210 is meant as a second astronomy course. ASTR 205 or equivalent is suggested for beginning students of astronomy. Those needing six credits of introductory astronomy may enrol in both courses in the sequence ASTR 205, ASTR 210.
