Water World

One of the most earthlike planets yet discovered is known by the euphonious title GJ 1214b. This planet, only 40 light years away, is about 2.7 times larger than the earth and 6.5 times more massive. The latest observations suggest that its bulk is 3/4 liquid water, surrounding an iron-nickel core.

Imagine the life that might roam that enormous warm ocean, thousands of times bigger than all the seas on earth!
