Photosynthetic habitable zones' could exist beneath radiation-filtering ice on Mars, offering scientists another region in which to hunt for alien life.

Microbial alien life could be found inside ice on the surface of Mars, according to a new study. It is almost certainly impossible to live on the surface of Mars. It is hit by high levels of ultraviolet radiation that would be harmful to anything that tried to survive there.

In a new study, researchers are suggesting something radical: that the Red Planet may be hosting life under its icy exterior. Researchers at NASA's Jet Propulsion Laboratory are positing that Mars' water ice deposits,

NASA study suggests that sunlight penetrating ice on Mars could support photosynthesis and possibly microbial life.

Could microbes endure just beneath the surface of Mars, in exposed layers of dusty ice? Scientists say such places are worth checking out.

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.

"Unlike Earth, Mars lacks a protective ozone shield, so there is 30 percent more harmful ultraviolet radiation at the surface," said researcher Aditya Khuller.

While evidence for life on Mars has never been found, a new NASA study proposes that microbes could find a potential home beneath frozen water on the planet’s surface. Through computer modeling, the study’s authors have shown that the amount of sunlight that can shine through water ice would be enough for photosynthesis to occur in shallow pools of meltwater below the surface of that ice.
