Homework Assignments

  1. Stellar motions near the center of the Milky Way
  2. The Andromeda Galaxy
    If you use the WWW form interface to SkyView instead of the Java interface, watch out for tricky false color images in astronomy ...
  3. Because of bad weather, some people were unable to do the "Radius of the Earth" assignment. Therefore, I've created a backup for it. You must turn in one of the two following assignments -- either is acceptable. You are free to turn in both, of course!
  4. Measure the distance to downtown Rochester


Reading material

There are two textbooks for this class. In addition, some of the material you need to read is taken from a small set of popular science magazines: Scientific American, Sky and Telescope, Astronomy, New Scientist. You can find all these in the RIT Library. I have collected articles from recent issues of these journals and placed them on electronic reserve. In order to access them, you need to know the login name and password for the course.

You can find a list of reading materials and instructions for accessing them on the Reading Materials page.
