Researchers from Skoltech and Chinese colleagues have identified a unique ion, dubbed aquodiium, potentially present inside Uranus and Neptune. This ion, resembling a water molecule with two extra protons, could influence the magnetic fields of these planets. The study reveals that under extreme pressure and temperature conditions, aquodiium forms and participates in ionic conductivity. This finding could explain the unusual magnetic fields of Uranus and Neptune, which differ from those of other planets.
