Possibility that atmospheric gases support life on other planets

"Cultivation-independent surveys have shown that the desert soils of Antarctica harbour surprisingly rich microbial communities .... We propose that atmospheric H2, CO2 and CO provide dependable sources of energy and carbon to support these communities, which suggests that atmospheric energy sources can provide an alternative basis for ecosystem function to solar or geological energy sources8,9. Although more extensive sampling is required to verify whether this process is widespread in terrestrial Antarctica and other oligotrophic habitats, our results provide new understanding of the minimal nutritional requirements for life and open the possibility that atmospheric gases support life on other planets."

More research needed but pretty cool
