Auroral Belts as Magnetically Localized Reactors for Prebiotic Chemistry on Early Earth

Most models of prebiotic chemistry focus on globally distributed energy sources such as ultraviolet radiation, lightning, or impacts. However, spatially localized environments capable of repeatedly concentrating reactive chemistry may also have played an important role in sustaining nonequilibrium chemical evolution on the early Earth. Here, we propose that Earth’s polar auroral belts may have acted as persistent, spatially focused environments in which prebiotic reactions could repeatedly occur
