ASTR 10, Descriptive Astronomy (V0076)
Spring Semester, 2004
Instructor: Dr. Korpela

Welcome to Astronomy 10!

This course provides an introductory look at the past, present, and future of the universe and its contents: stars, planets, galaxies, and we humans who seek to understand them. Astronomy has repeatedly challenged human thought, from the Copernican revolution to the recent discovery that the universe may be not only expanding, but also accelerating. Spacecraft have visited all of the planets except Pluto, and powerful telescopes take us even farther out in space and back in time. Through this course, I hope that you will gain some sense of the excitement that astronomers feel when they study the sky. Before long, you will be able to amaze your friends with the real story on black holes, the Big Bang, and the search for extraterrestrial life.

COURSE GOALS: Gain an appreciation of our place in the universe, and encourage a sense of awe about the night sky as well as topics in modern astrophysics. Understand what science is and is not, with particular attention to the scientific method as it applies to astronomy. Develop critical thinking and reasoning skills that can be applied to popular science literature.
