As I've mentioned, I am at McDonald Observatory assisting in a workshop for middle and high-school teachers. Above is a picture of an activity we used to illustrate the lives of stars. Each teacher had a different-colored balloon to represent red dwarfs, yellow sun-like stars, white hot stars, and massive blue stars. The white and blue star teachers were a little surprised when their balloons were popped to simulate a supernova.
Anyway, tomorrow is the last day of this workshop. We've been using telescopes late into the night, and are starting to wear down.
