1.3 km below Atlantic, scientists find water that may fuel sunless life

Scientists have uncovered new evidence that helps answer one of the biggest questions about the mysterious Lost City hydrothermal field, a unique underwater ecosystem deep in the Atlantic Ocean. By drilling more than a kilometre beneath the seabed, researchers found superheated water whose chemical composition closely matches the fluid that flows out of the Lost City's famous white chimneys, ScienceX reported.The discovery suggests that these unusual underwater vents are supplied by a hidden source of hot, hydrogen-rich water deep below the ocean floor. The findings help scientists better understand how life can survive in places where sunlight never reaches. It may also offer clues about existence of life in other worlds. The study was published in the journal Geochemistry, Geophysics, Geosystems.Life without sunlightThe Lost City hydrothermal field lies deep in the Atlantic Ocean and is unlike most ecosystems on Earth.
