Resumen de Stellar blasts that could cook up life
Planets blasted with stellar flares could be delicately balanced between nurturing life and killing it off. While such eruptions of high-energy particles can cause biological damage and chip away at a world's vital atmosphere, they might also kick-start the stuff of living things. There are a few ways for a young world to come by the energy required to forge simple atoms and molecules into complex organic compounds: heat from impacts, volcanoes, radioactivity or even ultraviolet radiation from starlight. Many of the exoplanets that look most promising for life orbit small, cool stars called red dwarfs. Because these stars emit less UV radiation but flare often, worlds like Proxima Centauri b could be on the receiving end of blasts that build organic molecules.
