2009 is the International Year of Astronomy. The International Astronomical Union and UNESCO said so! I think this is a marvelous idea and so do a bunch of podcasters.
365 Days of Astronomy is a project that will publish one podcast per day, 5 to 10 minutes in duration, for all 365 days of 2009. This is awesome! I'm going to volunteer. If you're a podcaster, if you've ever wanted to be a podcaster, or if you just want to talk about the stars for a few minutes, sign up and send something in.
