New ML model expands exoplanet photosynthetic habitable zone

By PulseAugur Editorial · [2 sources] ·

Researchers have developed a new machine learning model to estimate the Photosynthetic Habitable Zone (PHZ) for exoplanets, moving beyond Earth-centric assumptions. This agnostic model is based on fundamental thermodynamic and redox chemistry principles, simulating photosynthesis as a generic photochemical reaction. The model predicts that photosynthetic organisms can adapt to lower stellar flux by evolving larger light-harvesting structures, expanding the potential for photosynthesis beyond previously estimated ranges.
