How did water arrive on planet Earth?
Today, we learn just how much water Earth has, and where it came from in the first place. We'll take a joyride around the early solar system, climb a snow-capped peak, and learn how Jupiter may have played a crucial role in making Earth's oceans.
Extra credit: Drink some water, make a snowball, or watch the Kevin Costner classic Waterworld.
