Scientists Unearth 2-Billion-Year-Old Water in Canadian Mine
Scientists have discovered the oldest known water on Earth, locked away deep within the Kidd Creek Mine in Ontario, Canada. Estimated to be between 1.5 and 2.6 billion years old the water has remained sealed off from the surface, offering an unparalleled glimpse into the planet’s distant geological past.
The discovery was led by Professor Barbara Sherwood Lollar and her research team, whose work has major implications for understanding early Earth conditions, subterranean life, and even the potential for extraterrestrial life in extreme environments.
A Journey Three Kilometres Underground
The team made the discovery at a depth of about three kilometres inside the mine. Using isotopic analysis, they determined the water’s age, surpassing all previous records for ancient water anywh...
