Summary:
- Researchers have discovered a new phase of ice by squeezing water between two diamonds under high pressure.
- This new ice phase, called "ice-VII", has a unique crystalline structure that is different from the familiar hexagonal ice we see in everyday life.
- The discovery of this new ice phase helps scientists better understand the complex behavior of water under extreme conditions, which could have implications for understanding the interiors of icy planets and moons in our solar system.
