Maximum luminosity Type Ia supernova release energy at approximately 3.7x1036 W. Suppose a Type Ia supernova is found in a distant galaxy. The measured supernovae brightness is 10-14 W/m2. What is the distance to the galaxy? (Give your answer in millions of light years. You will want to calculate the distance in meters, and then convert to millions of light years.) B=\frac{L}{4\pi R^2}
