Electric Shock While Standing on Moon?
Andrew Fazekas, National Geographic
You won't get a literal jolt from looking at Sunday's full moon—but you might if you were standing on it. When the moon is full, it develops a strong electric field near the surface as it swings through Earth's magnetic "tail," according to new observations from a Japanese probe.
Earth's magnetic field creates a protective bubble known as the magnetosphere, which surrounds the planet and shields us from solar wind—a rush of charged particles, or plasma, constantly streaming from the sun. (Related:
