Description:
Within this use case you learn about supernovae, exploding or exploded stars. In particular you will use information on the Crab Nebula (the 1054 aD supernova registered by Chinese astronomers) to derive its distance: an example of how some very important information may be gained from very simple arguments and geometry.
