# What Is the Total Energy Radiated by a Supernova Equal to?

The total energy radiated by an exploding supernova is estimated to be approximately equal to the total amount of energy our sun will emit in its whole life span. The total energy of a supernova can be estimated with complex formulas, given the right variables. An exploding supernova can shine brighter than a galaxy for a brief time.

 For radiation H = A*e*sigma*T^4 You said e = 0.75 sigma = 5.67x10^-8W/m^2-K^4 However, you did not give me the Area so Now H = A*0.75*5.67x10^-8*900^4 = 27900*A Once you know area http://answers.yahoo.com/question/index?qid=200911...
