For those that may have listened to the 2006 edition of
Astronomy 161 by Prof Richard Pogge at the Ohio-State University, you may be interested in knowing that the Autumn 2007 version has just kicked off.
The old podcast subscriber link doesn't work now, but there's a new XML to put in your podcatching software to download the latest lectures. It's only just started - only 1 lecture has been given so far.
You can see the notes and follow the link to the podcast section, here:
Astronomy 161 - An Introduction to Solar System Astronomy
It's a brilliant lecture series and I recommend it to anyone who is interested in how the night sky works, motions of the heavens, history of astronomy and how we learnt things, discussions of keplers 3 laws and newtonian physics, followed lastly by a tour through our solar system.
Well worth the time invested. I enjoyed the 2006 series immensely and was part way through my second helping when I discovered the podcast link was now broken, and discovered the 2007 lectures.
Enjoy.
