Scientists Discover Water Turning into New Type of Ice. It Could Exist on Alien Worlds

Scientists Discover New Type of Ice

A new form of ice has been discovered by scientists, expanding the strange world of water.

When a drop of water was squeezed between two diamonds at pressures tens of thousands of times higher than Earth's atmosphere, it solidified into a new crystalline phase at room temperature.

This new structure, called ice XXI, was discovered by researchers led by Geun Woo Lee at the Korea Research Institute of Standards and Science (KRISS) in collaboration with scientists at the European XFEL and DESY in Germany.

Ice XXI is the twenty-first form of ice ever identified, joining a range of structures including hexagonal, cubic, amorphous, and superionic, each emerging under unique combinations of temperature and pressure.

Water's solid state is far more diverse than anything found in a freezer.
