Symmetries in the Universe, by Renee Hlozek and David Marsh
The 365 Days of Astronomy Podcast is a project that is publishing one podcast per day, 5 to 10 minutes in duration, for all 365 days of 2009. The podcast episodes are written, recorded and produced by people around the world. We are looking for individuals, schools, companies and clubs to provide 5 - 10 minutes of audio for the daily podcast. You can do as few as 1 episode or up to 12 episodes (one per month, subject to our editorial discretion). Our goal is to encourage people to sign up for a particular day (or days) of 2009.
