Astronomers claim to have found hints of life on Saturn's moon Titan which is much too cold to support even liquid water on its surface.
According to the 'New Scientist', the two potential signatures of life on Titan were found by Cassini spacecraft, but scientists have pointed out that non-biological chemical reactions could also be behind the observations.
Still many feel that exotic life-forms could live in the lakes of liquid methane or ethane that dot the moon's surface and that such microbes could eke out an existence by breathing in hydrogen gas and eating the organic molecule acetylene, creating methane in the process.
This would result in a lack of acetylene on Titan and a depletion of hydrogen close to the moon's surface, where the microbes would live, according to the scientists.
Now, measurements from the Cassini spacecraft have borne out these predictions, hinting that life may be present.
