For over half a century, scientists suspected a quiet but powerful electric field might be influencing Earth’s upper atmosphere. Now, thanks to a daring rocket mission near the North Pole, the mystery is finally solved. The discovery confirms that a hidden electric force stretches across the planet’s upper atmosphere, playing a major role in how Earth’s air escapes into space. This weak but steady electric field, called the ambipolar electric fi…
