ASTR 205 has a Challenge for Credit option.
Télé-université du Québec equivalency: PHY 2001.
ASTR 205 is a three-credit, introductory-level course designed to
- describe the Universe as we now understand it.
- explain how our current understanding came about.
- show how the scientific method forms the basis for both the tools and the theories of astronomy.
Part 1: The Sky—This unit describes the cosmos and traces the history of our attempts to understand it, including the tools developed to help us do so.
Part 2: The Stars—This unit describes light and how it carries information to us. It discusses what we have learned about the structure of stars and how they form, age, and die.
Part 3: The Universe of Galaxies—This unit describes how stars group together into galaxies, how galaxies are themselves distributed, and how we think this entire cosmic structure began and may end.
Part 4: The Solar System—This unit describes the characteristics and origins of planets and other bodies in our solar system.
