While actual evidence for life on Mars has never been found, a new NASA study proposes microbes could find a potential home beneath frozen water on the planet's surface.

NASA scientists believe life could exist beneath icy surface on Mars as a result of photosynthesis. In a new paper published in the Nature Communications Earth & Environment, the scientists explained that there are 'subsurface pools' beneath frozen water on Mars, where sunlight is allowing photosynthesis.

NASA researchers have proposed that beneath Mars’ frozen surface, meltwater pools could potentially support microbial life. Using computer models, scientists believe that sunlight filtering through dusty ice could create the right conditions for photosynthesis to occur in shallow subsurface water.
