New understanding of the solidification of high-pressure ice found in `ocean world` planets
(PHYSorg.com Physics)

A team of theorists from Lawrence Livermore National Laboratory (LLNL) has solved a long-standing puzzle in the nucleation of a high-pressure phase of ice known as ice VII, which is believed to exist near the core of `ocean world` planets recently detected outside of the solar system, and has recently been discovered to exist within the Earth`s mantle. The findings are described in a paper published today by Physical Review Letters.
