Cosmic-Ray Energy as a Potential Fuel for Subsurface Microbes on Enceladus, Europa, and Mars
To the point
Researchers such as Dimitra Atri note that life could exist on Enceladus, Europa, and Mars not from sunlight but from radiation-powered chemistry driven by galactic cosmic rays, potentially as microbes, supported by organic compounds on Enceladus and simulations of subsurface populations.
