You can use iTunes to listen to free astromony courses. I highly recommend Astronomy 161 and Astronomy 162 by Dr. Richard Pogge at Ohio State. About 60 free hours of instruction you can listen to on-line or download to an iPod. There are other courses as well. They usually have an associated wed site for course materials.
