An example of a simile used in explaining science

"The total energy output of the Crab nebula in the form of synchrotron radiation is 3 x 1038 ergs per second, which is 75,000 times more than the total energy output of the Sun, 4 x 1033 ergs per second. And this from a star which 'died' 900 years ago!"
