GC021 News Grab Bag #2

This week's episode contains updates to previous episodes based on recent news, and a little bit of news about Pluto (I don't have enough material for an episode all about Pluto, so it gets tossed in here). I also go through the results of the "Topics" survey I had on the website last month. Just to sweeten the pot, I wrap up with previews of coming attractions (physics fans -- rejoice!).
