September 26, 2018

A new study shows evidence that ancient Mars probably had an ample supply of chemical energy for microbes to thrive underground. “We showed, based on basic physics and chemistry calculations, that the ancient Martian subsurface likely had enough dissolved hydrogen to power a global subsurface biosphere,” said Jesse Tarnas, a graduate student in Earth, Environmental and Planetary Sciences and lead author of a study published in Earth and Planetary Science Letters. “Conditions in this habitable zone would have been similar to places on Earth where underground life exists.” Read more.
