Methanogenic Archaea from Siberian Permafrost as Prime Candidates for Life on Mars
Since ESA mission Mars Express determined water on Mars, fundamental requirement for life, and presence of CH4 in the Martian atmosphere, which could be originated only from active volcanism or from biological sources, it is obviously that microbial life could still exist on Mars, for example in for...
