Potential life on Mars likely lived below the surface: Study

WASHINGTON: If life ever existed on ancient Mars, it would have lived up to several miles below the surface of the Red Planet, likely due to subsurface melting of thick ice sheets fuelled by geothermal heat, according to a study. The research, published in the journal Science Advances, examined various Mars datasets to see if heating via geothermal or underground heat would have been possible 4.1 billion to 3.7 billion years ago or in the Noachian era. They showed that the conditions needed for subsurface melting would have been ubiquitous on...
