In the context of Mars, a habitable zone for photosynthesizing microbes could exist beneath a certain amount of ice. Too shallow and the strong ultraviolet radiation will cook them, but too deep ...

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

Researchers are particularly interested in understanding whether Mars was habitable, and if so, during what period.
