So what are my two favorite things in the whole wide world? Right: Doctor Who and astronomy. So you know I'm having a nerdgasm because I just found out that a new planetarium show called "We Are Astronomers" is narrated by David Tennant!
Even better, the animation is Little Big Planet style, which is too cool. Wanna see the trailer? It's quite good.
Of course, if you run a planetarium and need a show right now, I know a good one...
