Thank you for a great podcast!

This is the best podcast about astronomy I have found so far. The interaction between Fraser Cain and Pamela Gay, where Cain asks intelligent questions and Gay is the experts who answers them, works out really great. I have learned very much by listening to this podcast and I recommend it for everyone who is interested in astronomy.
