Evidence of Hot Water on Mars Found in Ancient Meteorite From Early Days of Solar System

Evidence of ancient hot water activity on Mars has been found in a 4.45-billion-year-old zircon grain from the NWA7034 meteorite. The findings, detailed in Science Advances, reveal that hydrothermal systems were active on Mars during the Pre-Noachian period. Researchers suggest these systems, essential for life on Earth, could have made Mars habitable in its early his...
