Summary:
- This article discusses the potential role of cosmic rays in fueling hidden life on Mars and other celestial bodies. Cosmic rays are high-energy particles that originate from outside our solar system and can penetrate deep into the subsurface of planets and moons.
- The article suggests that these cosmic rays could provide a source of energy and radiation that could support microbial life in the subsurface of Mars, where liquid water may exist. This could have implications for the search for extraterrestrial life beyond Earth.
- The article also mentions that similar processes could be at work on other icy moons in our solar system, such as Europa and Enceladus, which are known to have subsurface oceans and could potentially harbor life.
