The atmosphere has a natural electric field which is caused by worldwide thunderstorm activity, but is present in all weather conditions. Atmospheric electric fields, typically 100 V/m in calm weather ...

NASA has made a huge discovery: the ambipolar field, an invisible electric field around Earth that could reshape our understanding of our planet.

"Something had to be drawing these particles out of the atmosphere," Collinson said. Yet detecting a possible electric field proved difficult — the field was very weak, with detectable ...

The field is only about the strength of a watch battery — but it’s enough to thrust lighter ions from our atmosphere into ...
