Next year, every day, the 365 Days of Astronomy website will host a new podcast about astronomy... but it's all user-submitted. That means you! If you can record your voice, you can contribute to this website celebrating the International Year of Astronomy 2009.
My buddies Michael Koppelman and Pamela Gay have started it off with an introductory podcast that will tell you everything you need to know to help your 6,000,000,000 neighbors understand and appreciate the sky.
And yes, the sonorous tones at the beginning of the podcast are by George Hrab in all his hrabbie goodness.
