NASA has confirmed the existence of a long-hypothesized global electric field and its role in atmospheric escape and ionosphere shaping.
The geographic North Pole seen from the Endurance rocket with faint red and green streaks at the top caused by lens flare.Using observations from a NASA suborbital rocket, an international team of scientists has, for the first time, successfully measured a planet-wide electric field thought to be as fundamental to Earth as its gravity and magnetic fields.
Theorists predicted this outflow, which they dubbed the “polar wind,” spurring research to understand its causes. The hypothesized electric field, generated at the subatomic scale, was expected to be incredibly weak, with its effects felt only over hundreds of miles. If gravity alone were in play, the two populations, once separated, would drift apart over time. But they were given their opposite electric charges, and an electric field formed to tether them together, preventing any charges’ separation and counteracting gravity’s effects.
