Introduction to Stars, Galaxies, & the Universe
Winter Quarter 2006
Prof. Richard Pogge
1008 Evans Lab
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
