Astronomy 161 is an introduction to modern astronomy, with an emphasis on the Solar System. The course begins with an exploration of the historical development of astronomy, tracing the path by which we have come to our present understanding of the Universe. Along the way we will build up the basic toolkit of physical concepts that we will need for our later explorations, specifically the nature of light, matter, and gravitation. The second part of the course is devoted to an overview of modern solar system astronomy, with particular emphasis on the constituents of the solar system, comparative planetology (structure, surfaces, & atmospheres) and the history and evolution of the solar system. We will end by discussing the exciting new discoveries of planets around other stars.

Autumn Quarter 2007 begins on September 19.
These are the notes from Autumn Quarter 2006. As the quarter goes on, these files are likely to be taken down.

Note that the Audio files for the lecture podcasts from Autumn 2006 have not yet been moved, but are in the audio page. They will remain there until I figure out how to swap last year's podcast with this year's in a graceful fashion.

In the past, students have found it very helpful to make copies of these notes before class, and then follow along with them in lecture, making their own notes in the margins. You will find this much easier than trying to take detailed notes of everything I say.

I wish to strongly emphasize that these are only outlines of my lectures provided as aids to following along in class, not as substitutes for regularly attendance. Historically, students who have gotten into the bad habit of skipping class and just reading the web notes have performed one whole grade point below the class average.
