That's Astronomy, Not Astrology!

Yes, there is a difference...

Another excellent series of astronomy podcasts are actually recordings of two classes taught by Professor Richard Pogge at Ohio State University. Why these aren't on iTunes U instead of iTunes, I don't know, but these undergrad courses are excellent primers on astronomy. Astronomy 161 explains the local neighborhood - our solar system. Astronomy 162 deals with the big picture, deep time perspective - from the big bang to the heat death of the universe. Professor Pogge supplies copious supporting materials for 161 and 162 at the Ohio State website, but he does such a nice job explaining his topics you can get by without them...at least until you get home.
