Beneath the Mid-Atlantic Ridge lies the Lost City Hydrothermal Field, an ancient underwater city thriving for at least 120,000 years. This unique landscape is powered by the production of hydrogen and methane, creating a deep-sea ecosystem sustained by chemical reactions. Unlike volcanic vents, the Lost City relies on serpentinization, where seawater interacts with mantle rock to generate energy for life. The discovery of this alien-like world offers a glimpse into how life may have originated on Earth and the potential existence of similar environments on other celestial bodies. Microbial communities living within the mineral chimneys form the basis of a diverse ecosystem supporting various marine species. Scientists view the Lost City as a potential model for extraterrestrial life, with its energy production mechanism making it a long-term habitat compared to volcanic vents. However, this remarkable site is under threat from deep-sea mining activities that could disrupt its delicate balance. Researchers emphasize the importance of preserving the Lost City, advocating for its recognition as a UNESCO World Heritage Site to safeguard its scientific value and prevent irreversible harm. The Lost City may hold crucial clues to unlocking the mysteries of life's origins and expanding our understanding of potential life beyond Earth.
