Plastic Ice VII: Discovery of a New Water Phase

Scientists have identified a new form of ice, known as Plastic Ice VII, through advanced neutron-scattering experiments.
 

Key Features:
 

1. Forms at:
   1. Pressure: >3 gigapascals
   2. Temperature: >450 Kelvin
2. Exhibits a rigid crystalline structure where water molecules rotate freely, despite being in a solid state.
    

Significance:
 

1. Planetary Science: Helps simulate the interiors of ocean worlds and exoplanets.
2. Exoplanet Habitability: May play a role in nutrient transport in deep oceans, influencing the potential for alien life.
3. The discovery alters our understanding of water behavior in outer space environments.
