To the naked eye, ancient rocks may look completely inhospitable, but in reality, they can sustain an entire ecosystem of microbial communities in their fracture waters isolated from sunlight for millions, if not billions, of years. New scientific findings discovered the source of the essential energy to sustain the life kilometers below Earth's surface with implications for life not only on our planet but also on Mars.
