New research indicates that photosynthesis might occur beneath the surface of dusty ice at Mars’ mid-latitudes, where conditions could allow for liquid water and sunlight.

While the study doesn’t claim that life exists on Mars, it identifies areas to explore for signs of life.

The research suggests that a thick layer of ice can protect subsurface water from harmful ultraviolet radiation while allowing enough sunlight for photosynthesis.

Simulations show that dusty Martian ice could melt from within, creating “radiative habitable zones” at depths between 2 inches and 10 feet, depending on the dust content, Space.com has reported.

This study, published in Nature Communications Earth & Environment, aims to refine simulations of potential melting and further investigate the habitability of Martian environments.
