Weird water lurking inside giant planets - space - 02 September 2010 - New Scientist

Weird water lurking inside giant planets: "Simulations in 1999 and an experiment in 2005 hinted that water might behave like both a solid and a liquid at very high pressures and temperatures. Under such conditions, the oxygen and hydrogen atoms in the water molecules would become ionised, with the oxygen ions forming a lattice-like crystal structure and the hydrogen ions able to flow through the lattice like a liquid. This 'superionic' water, forming at temperatures above 2000 �C or so, should glow yellow."
