An opportunity to learn, and an opportunity to hang out with other space geeks -- both are presented in this week's show as we talk with planetary scientist Bruce Betts about his free, online Intro to Astronomy course, and with two of the people behind the new season of SpaceUp Unconferences. Chris Radcliff and Marimikel Charrier will tell you how to find one and how to start your own. Emily Lakdawalla has opened up the history of the Galileo mission to Jupiter, while Bill Nye the Science and Planetary Guy remembers meeting famed physicist Stephen Hawking. All this, and a new What's Up space trivia contest.
