20 December 2016 Current Affairs: University of Toronto scientists have discovered the oldest water sample dating back to about two billion years, more than 500 million years more ancient than the previous oldest samples.
The water pool was found at a depth of nearly 3 kilometres in a Canadian mine. The discovery could give clues about life forms beneath the surface of other planets.
The new discovery for the oldest water source beats the old record by 500,000,000 years. Water also found in Kidd Mine at 2.4 kilometers was estimated to be 1.5 billion years old.
Although no ancient sources of water beneath the Earth’s surface have ever been found to contain life, the recent finding suggests it is capable of sustaining life. Traces of sulphate in the water provided scientists with a clue that it could have supported primitive life such as unicellular organisms, prompting scientists to consider similar possibilities below the surface of Mars, Saturn or other planets and moons.
