" The superionic ice could help explain the lopsided, off-center magnetic fields of Uranus and Neptune, the solar system’s seventh and eighth planets that are known as ice giants and were visited briefly by NASA’s Voyager 2 spacecraft in the 1980s. Instead of Earth’s magnetic field generated at the core of the planet, the fields of those icy bodies may originate, in part, within shells of superionic ice inside their mantles. " cool!!
