Giant Veil of “Cold Plasma” Discovered High Above Earth
Clouds of charged particles stretch a quarter the way to the moon, experts say.

Clouds of “cold plasma” reach from the top of Earth’s atmosphere to at least a quarter the distance to the moon, according to new data from a cluster of European satellites.
Earth generates cold plasma—slow-moving charged particles—at the edge of space, where sunlight strips electrons from gas atoms, leaving only their positively charged cores, or nuclei.
