Bad source, i knows, but too lazy to find better, the link has an official NASA video, so legit afaik.
http://www.thesun.co.uk/sol/homepage...cle2133475.ece Nasa scientists say the gas emissions could have either a geological or biological source - as The Sun exclusively revealed today. Nasa announced its historic findings on its online television channel Life is responsible for more than 90 per cent of the Earth’s atmospheric methane. Experts believe there is a good chance that organisms produced the gas emissions - as large as some of those seen on Earth - on Mars too Scientist Michael Mumma of NASA’s Goddard Space Flight Center said: “This raises the probability substantially that life was there or still survives at the present. “We think the probability is much higher now based on this evidence.” The bugs that made it may have vanished millions of years ago, leaving the methane frozen under the planet’s surface. But another possibility is that some hardy organisms still survive on the Red Planet, living underground without sunlight and using hydrogen from water for energy. Similar microbes exist on Earth. Methane produced by the action of water on hot carbon bearing rocks, as occurs in volcanic regions on Earth, is the alternative explanation. Whatever the source is, scientists agree that something is replenishing the methane. The find is seen as exciting new evidence that Martian microbes are still alive today. Some scientists reckon methane is also produced by volcanic processes. But there are NO known active volcanoes on Mars. Furthermore, Nasa has found the gas in the same regions as clouds of water vapour, the vital “drink” needed to support life. Experts speculate that the methane is being emitted as a waste product by organisms called methanogens living in water beneath underground ice. And they would have to be alive today because the methane would otherwise have been lost from the Martian atmosphere. John Murray — a member of the Mars Express European space probe team — believes the mini-Martians may be in a form of suspended animation and could even be REVIVED. He has found overwhelming evidence of a vast frozen ocean beneath the dust near the Martian equator where simple life could have thrived as microbes. Today’s briefing will feature a star panel of Mars experts headed by Michael Meyer, chief scientist for Nasa’s Mars programme. UK Mars expert Professor Colin Pillinger believes the methane can only point to the presence of life on the planet. His ill-fated Beagle 2 probe was carrying a laboratory that would have looked directly for such signs of life when it crashed on Christmas Day 2003. Should make you happy golemfrost! |
