Martian methane belch: From rocks or microbes?
A surprising and mysterious belch of methane gas on Mars hints at possible microbial life underground, but also could come from changes in rocks, a new NASA study found. The presence of methane on Mars could be significant because by far most of the gas on Earth is a byproduct of life ? from animal digestion and decaying plants and animals.
Mars Methane Gas May Signal Biological Activity - Bloomberg

Mars?s surface shows signs of the presence of methane gas, a marker of biological activity or even primitive life forms, said scientists studying the Red Planet with telescopes.
Methane can be produced by either living organisms or geological processes, scientists said. The gas may come from organisms like some on Earth that live more than a mile below the surface.
?Both geochemical and biological origins have been explored, but no consensus has emerged,? said the scientists led by Michael Mumma of NASA?s Goddard Space Flight Center, in the study to be published in tomorrow?s edition of the journal Science.
