9/ the 2011 Nobel Prize in Physics was awarded to 3 men who study white dwarf supernova explosions, which are known as Type la supernovae. The following problem is designed to give you a feel for what they did, and the sorts of apparent brightnesses and distances they were working with. A typical Type la supernova explosion has a luminosity of 1.72 x 10^36 W. If we observe such a supernova to have an apparent brightness of 1.25 x 10^-17...
