The strange, wildly tilted magnetic fields of Uranus and Neptune have puzzled scientists since NASA's Voyager 2 spacecraft explored the planets in the 1980s. New simulations suggest that extreme conditions deep inside these icy giants create unusual electrical properties that could explain their mag netic fields. Remarkably, the models indicate that their magnetic poles could shift by tens of degrees within just a few decades, far faster than Earth's. ...read more read less
