An international research team has discovered a new form of superionic water, formed under extreme temperatures and pressures, which could help explain the magnetic fields of ice giants like Uranus and Neptune. This phase allows hydrogen ions to move freely through a solid lattice of oxygen atoms, revealing a complex structure that combines face-centered cubic and hexagonal close-packed stacking. The study involved over 60 scientists and utilized high-precision measurements at facilities in Germany and the USA.
