Billion-year-old water could hold clues to life on Earth, Mars
A team of Canadian and UK researchers has discovered what may be some of the oldest pockets of water on the planet – and they may contain life.
The team, which included McMaster’s Greg Slater, analyzed water pouring out of boreholes in a mine nearly 2.5 km below the ground in Timmins, located in northern Ontario.
Their findings, published May 15 in the journal Nature, could force us to rethink which parts of Earth are fit for life.
The researchers used isotopes of helium, neon, argon and xenon to demonstrate that the water was isolated deep beneath the Earth for an average of 1.5 billion years and possibly up to 2.6 billion years, making it some of the oldest water ever observed. More...
