A Quadrillionth Of A Watt

Bad Astronomy shows us a weird time-lapse of the Very Large Array, which reminded me of an episode of Cosmos and this reasonably stunning piece of information:

Modern radio telescopes are exquisitely sensitive; a distant quasar is so faint that itsdetected radiation amounts perhaps to a quadrillionth of a watt. The total amount of energy from outside the solar system ever received by all the radio telescopes on the planet Earth is less thanthe energy of a single snowflake striking the ground. 

We got plenty of snowflakes today, but I will trust Carl and not test his assertion.
