Is salt the key to unlocking the interiors of Neptune and Uranus?

The interiors of several of our Solar System’s planets and moons are icy, and ice has been found on distant extrasolar planets, as well. This ice must exist under extreme pressures and high-temperatures, and potentially contains salty impurities, too. New research focuses on the physics underlying the formation of the types of ice that are stable under these paradoxical-seeming conditions. It could challenge current ideas about the physical properties found inside icy planetary bodies. —> Read More
