Scientists have discovered a source of water deep beneath Ontario, Canada, that has been isolated for more than a billion years. Talk about vintage.
The water source was found some 2.4 kilometres below the surface and was rich in methane and hydrogen, meaning that possible life in the water would have had good support.
The find breaks the previous record for how long a source of water has stayed free of contamination by some ways and could potentially and/or speculatively be good news for people looking studying whether Mars once held life. At least according to Pete Burnard, a geochemist at the Centre of Petrographic and Geochemical Research in Vandœuvre-les-Nancy, France.
The surface of Mars once held water and its rocks are chemically no different from those on Earth, he says. “There is no reason to think the same interconnected fluids systems do not exist there.”
