A UK-Canadian team of scientists has discovered ancient pockets of water, which have been isolated deep underground for billions of years and contain abundant chemicals known to support life. This water could be some of the oldest on the planet and may even contain life. Not just that, but the similarity between the rocks that trapped it and those on Mars raises the hope that comparable life-sustaining water could lie buried beneath the red planet’s surface.
The findings, published in Nature, may force us to rethink which parts of our planet are fit for life, and could reveal clues about how microbes evolve in isolation.
