Key Points

About Eugene Parker

In the mid-1950s, Eugene Parker proposed a number of concepts about how stars — including our Sun — give off energy.
He called this cascade of energy the solar wind, and he described an entire complex system of plasmas, magnetic fields and energetic particles that make up this phenomenon.
Parker also theorized an explanation for the superheated solar corona, which is — contrary to what was expected by then-known physics laws — hotter than the surface of the Sun itself.
His theory suggested that regular, but small, solar explosions called nanoflares could, in enough abundance, cause this heating.
