Welcome to Astronomy! You
are about to embark on an ambitious project - to survey our known Universe in
one short semester. We hope that you'll find this course enjoyable and walk
away with a better knowledge and understanding of the universe that we live in.
With that goal in mind, the course attempts to focus on major concepts in
astronomy and where possible tie those concepts into issues relevant to your
life. For example, global warming, an important worldwide issue for the 21st
century, is also central to understanding the differences between the
environments of Venus, Mars, and Earth. At a more philosophical level, understanding
how our universe works and how planets, stars, and galaxies form and evolve
gives us a better perspective on our place in the universe and how special
planet Earth is to our continued survival.
