new planet-wide electric field that is as fundamental to Earth as gravity has been discovered in a major scientific breakthrough. The ambipolar electric field, which begins 150 miles above the planet, has been described as a “great invisible force” that lifts up the sky and is responsible for the polar winds. The polar winds interact with the jet streams to help drive the majority of weather patterns across the globe. Until now, the field had only been theorised, but a Nasa team, which includes scientists from the University of Leicester, has now sent a rocket into the field and measured...
