Mr Science over at the 365 Days of Astronomy Podcast

A little while back in our 99th episode, we discussed the 6 unknown mysteries of our solar system. This show has recently been played in the 365 days of astronomy podcast, which is a project that publishes one astronomy-themed podcast per day for all 365 days of 2009. 2009 is the International Year of Astronomy, which is described as a global effort initiated by the International Astronomical Union and UNESCO to help the citizens of the world rediscover their place in the Universe through the day- and night-time sky, and thereby engage a personal sense of wonder and discovery.
