Ok, I'm an astronomy student and I just started working at the Thomas Planetarium in Anchorage, Alaska. Now, the astronomer that runs the planetarium wants me to design and run quick, educational shows during the day when most of the traffic is K-12 field trips. What would you want to learn about, what astronomy questions would you want answered if you came into the planetarium that wouldn't be too complicated for children to understand and that could be covered in about 15 minutes? — asked by Anonymous
What was life like when there were nine planets?
