I love this podcast with Seth Shostak from the SETI Institute. Years ago, when I worked at the reference desk at Mountain View Public Library, Seth was a frequent visitor.
As I was working with 6th graders on their Astronomy projects recently, I kept running across his writing on the web and in the online databases. I didn't tell the students that I knew the author (although I highly doubt if he would remember me), but I should have introduced them to the podcast. They would love his humor and learn so much about science!
