Gas in Rocks May Sustain Alien Life Discovery News

Huge colonies of Earth microbes are living off of hydrogen gas released by common rocks, raising the possibility of similar life forms on Mars, says a NASA researcher. “The hydrogen comes from a subtle chemical reaction that occurs within rocks that were once hot or even molten,” said Friedemann Freund, a physicist, geologist and chemist at NASA’s Ames Research Center whose work appears in the current issue of Astrobiology Journal.
