Colbert Nation and Derrick Pitts

Stephen Colbert had my good bud and all-around astronomer Derrick Pitts on the show last night.  Derrick’s at the Franklin Institute in Philadelphia, and he curated an exhibit about the astronomer Galileo Galilei.  Derrick’s a funny guy, a good sport, and I’ve known him in planetarium circles for a number of years. Check it out — Derrick scores some good ones with Stephen Colbert.
