Salty water just underneath the surface of Mars could hold enough oxygen to help the sort of microbial life that developed and thrived on Earth billions of years back.
In a few areas, the measure of oxygen accessible could even keep alive a crude, multicellular creature, for example, a wipe, they revealed in the diary Nature Geosciences.
"We found that brackish waters - water with high convergences of salt, on Mars can contain enough oxygen for organisms to inhale" said lead creator Vlada Stamenkovic, a hypothetical physicist at the Jet Propulsion Laboratory in California.
"This completely reforms our comprehension of the potential for life on Mars, today and previously" he told AFP.
Up to now, it had been expected that the following measures of oxygen on Mars were lacking to manage even microbial life.
"We never imagined that oxygen could assume a job for life on Mars because of its irregularity in the environment, around 0.14 percent," Stamenkovic said.
By examination, the nurturing gas makes up 21 percent of the air we relax. On Earth, vigorous, that is oxygen breathing of living things developed together with photosynthesis, which changes over CO2 into O2. The gas assumed a basic job in the development of complex life, prominent after the supposed Great Oxygenation Event exactly 2.35 billion years back.
In any case, our planet additionally harbors organisms at the base of the sea, in bubbling hot springs that subsist in situations denied of oxygen.
