Caption The phase diagram shows the state of water (H2O) under very high pressure (X-axis) and temperature conditions (Y-axis). These conditions apply in the interior of the ice planets Uranus and ...

Water can exist in two liquid states under extreme conditions, reshaping our understanding of its molecular behavior.

Scientists have uncovered a key finding to one of water's unique properties: at high pressure and low temperature, liquid water separates into two distinct liquid phases -- one high-density and one ...
