Ο ΠΛΑΝΗΤΗΣ ΜΕΣΑ ΣΤΗ ΓΗ 3 ''HYDROTHERMAL VENTS''

''In the late 1970's, scientists on a routine study of the ocean floor in the Pacific made a discovery that would rock the entire scientific community. On the East Pacific Rise not far from the Galapagos Islands, nearly 8000 feet below the surface, was a strange alien landscape littered with what looked like chimneys expelling clouds of black smoke. Surrounding these chimneys was a unique type of ecosystem that had never been seen before. Until this day, science had always assumed that all life on Earth obtained its energy from the Sun. The plants convert sunlight into energy through a process called photosynthesis. The plants, in turn, provide food for countless species of animals in a complex web of life. But here, facing the deep-sea submersibles, was a sight that challenged those assumptions. Here was proof for the first time that life could be sustained by the Earth itself..''
