Hey all. I wanted to mention a new astronomy related podcast I'm involved in. It is: http://www.slackerastronomy.org .
We do a weekly podcast on a recent news item in astronomy. We try to be humorous and colorful but we also try not to dumb it down. Three of us put it together. Two of us are professional astronomers and the other has a degree in broadcasting. This is all non profit and with no ads- we do it just for fun. We will cover popular astronomy news but also delve into the papers and cover things that go under the radar but are still interesting.
You don't need an iPod to listen, you just need an MP3 player and most computers built in the last 2 years have them built in.
