Life in Europa’s ocean could feed on rocks’ radioactive decay

Life in the ocean beneath Jupiter's moon Europa could potentially derive energy from the radioactive decay of rocks, presenting a hopeful alternative energy source. The unique geological and environmental conditions on Europa may allow for life forms to utilize energy produced by radioactive decay, challenging the conventional belief that extraterrestrial life must rely on sunlight or organic matter. This perspective suggests that harsh conditions and lack of sunlight on Europa do not eliminate the possibility of life, as alternative biochemical processes could sustain it. The idea of life existing in extreme environments and deriving energy from unconventional sources is gaining renewed attention as exploration of Europa intensifies.
