Scientists have recently discovered a new form of "salty" ice that could exist on the surface of some extraterrestrial moons in our solar system. This new type of ice is a combination of water and a type of salt called magnesium sulfate, which is also known as Epsom salt. An international team of researchers discovered two new crystal structures for salty ice, also known as solid hydrate made of water and sodium chloride. The properties of the newly discovered material match those of the substance seen on the surface of icy moons like Europa and Ganymede, and may provide clues
