ASTR 101 - Introductory Astronomy

(NSLD, GEEL)

A basic introduction to astronomy that emphasizes appreciation of the Earth’s relationship to the universe. The basic laws of physics as they apply to astronomy are covered, along with telescopes and data collection and analysis techniques utilized by astronomers. Also covered are the evolution of stars, the solar system, galaxies, and the origin and evolution of the universe. Laboratory sessions, both computer- based and other, give practical application to material covered in lectures. Two nighttime observing sessions are also included. Assessment Level(s): ENGL 101 /ENGL 011 , MATH 050 . Three hours lecture, two hours laboratory, one hour discussion each week.

4 semester hours

May not be taken concurrently with MATH 017 or MATH 020 or MATH 030 or MATH 045 without appropriate Math assessment score.
