In the photon energy range 2 to 10 keV, X rays coming from the Crab Nebula have an intensity of 2.4*10^(-11) W/m^2 when they reach the earth. The Crab Nebula is 6,523 light years away from the Earth. Assume that the X-Rays are emitted uniformly in all directions by the source. Calculate the power emitted by the Nebula in the form of X-rays in this energy range, in watts.
1 light year = distance that light travels in one year = 3.16*10^7 s * 3*10^8 m/s
