Case Study: Rocks in the outer solar system: Normal and Anomalous Properties of Water Ice 

Water ice is one of the abundant minerals in the universe. The only form of ice that that we encounter naturally on Earth is that which is called ice Ih. However, by changing the conditions of pressure and temperature, the atoms in the ice can be made to rearrange, and – as of 2021 – 19 different crystalline ice structures are now known; several of these high-pressure ices are thought to occur in the icy bodies of the outer solar system.
