Ice-crystal halo: haloes such as the one seen here (photographed in Quebec City) are produced when light from the Sun or Moon interacts with ice crystals suspended in the atmosphere. Scheiner’s halo ...

Snowflakes are usually hexagonal, but under certain conditions, they can look like diamonds. This was reported by The Xinhua News Agency. In a new study published in the journal Nature, Chinese ...

The conventional view among scientists about how ice forms is that it begins from seeds in which water molecules are packed together in a hexagonal structure and maintains this structure as it grows.

Computer simulations show that cubic and hexagonal ices nucleate through the formation of a tetragonal metastable ice phase. Moreover, the authors find that for the mW model the melting curve of ice 0 ...

Something almost magical happens when you put a tray full of sloshing, liquid water into a freezer and it comes out later as a rigid, solid crystal of ice. Chemists at the University of Utah have ...
