Imagine that you are observing the light from a distant star that was located in a galaxy 100 million light years away from you. By analysis of the starlight received, you are capable to tell that the image we see is of a 10 million-year-old star. You are also capable to guess that the star will have a total lifetime of 50 million years, at which point it will end in a catastrophic supernova.

a) How long will it be before we receive the light from the supernova event?


b) Has the supernova already occurred? if so, when did it occur?
