Astronomers using a 2.0-mm-diameter telescope observe a distant supernova−−an exploding star. The telescope's detector records 8.7 ×× 10−11−11 JJ of light energy during the first 10 ss. It's known that this type of supernova has a visible-light power output of 4.5 ×× 103737 WW for the first 10 ss of the explosion. Part A How distant is the supernova? Give your answer in light years, where one light year is the distance light travels in one year. The speed of light is 3.0 ×× 1088 m/sm/s. Express your answer in light years.
