ASTR 10, Descriptive Astronomy (V0076)
Spring Semester, 2004
Instructor: Dr. Korpela
Chabot trip is delayed until Apr 23!
The predicted rain never did materialize, but only one person showed and there
were some clouds coming in, so we'll delay one week.
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

- The link to old lectures was missing. It's here.
- We've scheduled the Chabot field trip for April 16.
- Homework #4 is due Apr 15..
- PROJECT #1 is due Apr 22.
- PROJECT#2 is Due May 6.
- EXAM #2 is this April 15. Those who need a makeup should contact
Dr. Korpela by April 1st. You will need to bring a #2 pencil and a ScanTron 882-E
form. ScanTron forms are available at most bookstores near the UC Campus.
If you haven't been to the website before now, an introduction to its
important features can be found in the notes for the first
lectures, in the Archive of Administrative Notes.
As I said in class, those that can download materials from this site should
do so, in order to save on photocopying (and the weight of what I carry!).
- Telescope Viewing:
We've scheduled a field trip to Chabot for telescope viewing on April 16, however,
you can go to Chabot any Friday or Saturday night. Follow the Local
Astronomy link below to investigate this and other options.

the night sky! If you have binoculars, search Orion's belt for the Orion

- Remember to look up! Astronomy is, after all, the
study of the stars etc! Think about the scale of distances,
motions and times as you gaze at the sky. If you can see
planets and/or the moon, try to picture where you are on the earth, and
where the planet is in its orbit.
exercises we've done should help.
- Planets: This week Venus in the west after sunset.
is the brightest object in the evening sky (apart from airplanes,
sun, and moon).
Jupiter is the east at sunset. Saturn is above the top of orion.
Mars can be seen faintly glowing red in the southwest after sunset.
- Stars: Remember that almost everything that can be seen with
the naked eye is part of our own Milky Way Galaxy! (The Andromeda Galaxy is
an exception). Notice that it's hard to see the disk of our Galaxy with
your naked eye, but we do in fact live way out on one side of that disk.
Think about which stars are likely to be young, and
which are likely to be old! Think about which are about to die, and how.
Keep an eye on Betelgeuse! Think of all the pulsars and black holes you
can't see with your naked eye! Remember that all of these objects that
you can see with the naked eye are inside our own galaxy! (Exceptions
are the Andromeda Galaxy (visible from dark locations) and the Large and
Small Magellanic Clouds (visible from the southern hemisphere).

exams for Exam #2 MUST be completed prior to the originally scheduled exam
date. Please contact Dr. Korpela prior to April 1 if you need to reschedule.
Last Thursday Night's Lecture:
Find out what the goals of last night's lecture were in the
What Was Important notes. Some more details
are found below.
The lecture notes for this section may be found here
(powerpoint) or here (html). Notes for older
lectures are here.
Last thursday we went into the details of stellar structure and how stars work.
You don't need to know a lot of the details, but you do need to know that fusion
in main sequence stars turns 4 protons into a helium nucleus, 2 positrons, 2
neutrinos, and energy in the form of Gamma rays. You should also understand how
rates of fusion are governed by temperature and pressure and how this, in
combination with hydrostatic equilibrium, results in a thermostat that controls
the luminosity of a star.
You may have trouble parking some Thursdays because of the basketball
games. Men's games create the most difficulty

If you don't yet have the text, much of the material required for Homework #1
is contained in the handouts, and the remainder can be found in
the (different) online textbook at
If you are a little confused, don't panic.
It is not my intention to fail students who attend the classes and seriously
work on all the homeworks and assignments
