Description:

The discovery of electric currents everywhere in space makes the meteorological vocabulary of astrophysicists obsolete.

This false-color image of Saturn in ultraviolet light shows the complete circle of an aurora around Saturn’s south pole and part of the aurora around its north pole. From almost the beginning of the space age, plasma physicists have known that electric currents flow from regions high above Earth’s equator to the auroral regions around the magnetic poles and that these circuits power the auroras. Presumably, Saturn’s auroras are lit by similar circuitry. Read More
