Overview

Astronomy 162 is an overview of modern astrophysics beyond our Solar System, picking up where Astronomy 161 left off. The course is divided into three interlinking parts that will review what astronomers have learned about the stars, the galaxies, and the Universe. We will examine how these ideas have been developed and tested against observations, and explore a few of the outstanding problems faced by current astronomical research. The questions to be addressed include: What are stars? Where do stars get their energy? What is the fate of the Sun and other stars? What are galaxies? What is the Big Bang model of the Universe? What is "Dark Matter"? What is the ultimate fate of the Universe?

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.
