The Crab Nebula is a cloud of glowing gas located about 6500 light years away. Viewing from the Earth, its apparent visual brightness is only of our Sun (the solar luminosity is W, and the distance of the Sun is about m). Astronomers estimate that the power observed in visual wavelengths only accounts for about 1/100 of the total power needed for energizing the Crab Nebula. Estimate the total power needed for energizing the Crab Nebula (in Watts). g
