In 1977, a deep-sea expedition discovered hydrothermal vents on the ocean floor, revealing a unique ecosystem thriving without sunlight. These vents, spewing mineral-rich hot water, support life through chemosynthesis, a process where bacteria convert chemicals into energy. This discovery challenged traditional views on life's origins, suggesting that life could exist in extreme environments. The vents are part of a global mid-ocean ridge system, and their study has implications for understanding life's beginnings on Earth and the potential for life on other planets, such as Jupiter's moon Europa.
