A new study by Curtin University has revealed what could be the oldest direct evidence of ancient hot water activity on Mars. The research focused on a 4.45 billion-year-old zircon grain from the Martian meteorite NWA7034, also called Black Beauty. The analysis found geochemical signatures suggesting that water-rich fluids were present, providing evidence that Mars may have been habitable in the past.
