Betelgeuse: The star Betelgeuse in the constellation Orion might go supernova any day now, or perhaps it already has! Since it is 600 light-years away, the light from the explosion would not be expected to reach us until 600 years after the explosion happened. In astrophysics, we will learn to say that we are currently "outside the light cone of the explosion." If Betelgeuse went supernova 599 years ago, releasing energy E_betelgeuse_supernova Joules of energy, what maximum energy should we expect to hit a square meter of Earth next year, when the shockwave reaches us?
