WASHINGTON (AFP) – Plumes of methane gas detected on Mars could be a sign of geological or biological activity -- and possibly the latest indication that life can be sustained on the Red Planet, according to a study released Thursday.
The presence of methane implies active geological, or possibly even biological, processes on Mars, and the amount of methane observed on the "Red Planet" is comparable to some active sites on Earth, the study published in the journal Science found.
"We believe this definitely increases the prospects for finding life on Mars," principal researcher Michael Mumma told The Washington Post.
"No other discovery has done as much to increase the chances of finding life."
