There is ice almost everywhere on our planet. It can cool your glass of water, form on the surface of lakes during the winter or dominate the landscape of the Arctic and Antarctic. On Earth, we refer to ice as water in a solid state. Elsewhere in the Solar System, pressure and temperature are different—they can be extreme! —and they affect the state of the molecules (solid, liquid, gas). On some moons or planets, gases such as ammonia or carbon dioxide are present in the form of ice because of the ambient conditions. Ice is thus a general term encompassing a vast array of substances, which can come in surprising forms. Let's take a look at these icescapes!
