Earth’s magnetosphere, once thought to have a simple electric polarity pattern, has revealed a surprising twist. New satellite data and advanced simulations show that the morning side of the ...

For the first time, scientists have measured a long-sought global electric field in the Earth’s atmosphere. This field, called the ambipolar electric field, was predicted to exist decades ago but ...

This alternating electric field produces what are called dielectrophoretic forces, which are essentially a non-uniform electric field creating a traveling wave that pushes dust across the surface. By ...

All celestial bodies—planets, suns, even entire galaxies—produce magnetic fields, affecting such cosmic processes as the solar wind, high-energy particle transport, and galaxy formation. Small-scale ...

NASA scientists have discovered a planet-wide electric field surrounding Earth, confirming a 60-year-old hypothesis. Studying the field could yield some vital information about how our planet's ...
