NASA has discovered yet another planet in our solar system that contains water. Saturns brightest moon, Enceladus, has been found to contain stress fractures on its icy surface that expand and contract as it circles Saturn. Such a flexible surface can only mean one thing — a planet covered in water. What's more, the water below the frozen surface could be hot, and with hot water comes biological growth.
Not surprisingly, Enceladus isn't the only planet that NASA has its eyes on for extraterrestrial life in and out of our solar system. Check out three more planets that could contain life, or have all the fixings for alien life in the future.
