Summary:Star in a Box allows you to explore one of the most enigmatic tools in astronomy -, the Hertzsprung-Russell diagram. When you first open the box you start with a star with the same mass as the Sun but you can change this to a different mass at any time. The tracks that you see on the graph map the life cycle of the star. You can play the animation of the star moving around the diagram, and see how its brightness, size, surface temperature, and mass change. Stars can take billions of years to go through their lives with the dramatic events taking place in relatively short periods of time. In the animation we speed up time when the star is not really changing much and slow things down for the dramatic phases of the star's life.
