Under extreme planetary conditions, water turns into a strange, electricity-conducting solid hidden deep inside giant planets.

Scientists discover water that's solid and liquid. Superionic ice found in lab could explain Uranus and Neptune's bizarre ...

For decades, Uranus and Neptune have been filed neatly into the “ice giant” drawer, shorthand for worlds built mostly from ...

At extreme pressures and temperatures, water becomes superionic — a solid that behaves partly like a liquid and conducts ...
