SOLAR PARTICLES. “Typical solar proton events (SPEs) produce a fluence of about 10(9) protons cm−2 on Earth. Because the Sun was considerably more active in the past, it is highly likely that such eruptions might have occurred on the Sun more frequently. The higher energy component of these SPEs, just like Galactic cosmic rays, is capable of penetrating underground, and would have increased the flux of secondary particles in subsurface environments. A combination of particle flux along with water and nutrients might provide ideal conditions for life to originate and evolve until conditions on the surface become optimal.”
