NASA Confirms Existence of Earth's Ambipolar Electric Field

A weak but fundamental electric field, first hypothesized over 60 years ago, has been measured, revealing its role in atmospheric dynamics.

The ambipolar electric field is responsible for the polar wind, a stream of charged particles escaping Earth's atmosphere.
NASA's Endurance mission detected a change in electric potential of 0.55 volts, confirming the field's presence.
The field counteracts gravity, lifting ions to higher altitudes and contributing to the density of the ionosphere.
This discovery could reshape our understanding of atmospheric evolution on Earth and other planets.
The findings were published in the journal Nature, marking a significant milestone in atmospheric science.
