SCI 103 Introductory Astronomy

Credits: (3)
The Universe: the solar system, stars, galaxies, and cosmology are examined in the light of continuing discoveries of modern astronomy in the space age. Satisfies the science elective requirement of the Math/Science curriculum and also satisfies the science requirement of those curricula which requires science. Three class hours or equivalent per week.
