研究人员用金刚石压砧将水分子压缩到数百万个大气压,并用激光加热到数千摄氏度,发现了名为六方密堆积冰的新冰相。这种超离子冰的氢原子能像液体一样移动,导电性远高于普通冰,或能解释天王星和海王星倾斜且偏离中心的磁场。另一个团队还发现了在近两倍压力下稳定的冰XXII。
原文开头

These ice giant planets have extremely unusual magnetic fields, which may be explained by strange forms of ice deep under their surfaces. The water ice that we are familiar with in everyday life is just one of more than 20 different phases, each of which has a different crystal structure to its molecules. Under increased temperature and pressure, the hydrogen and oxygen that make up the water rearrange, giving each phase unique electric and mechanical properties. …
