Ice is a key component in the universe. There are frozen water molecules on comets, moons, exoplanets, and in your drink as you cool off from the summer heat. However, under the microscope, not all ice is the same, even though it is made of the same components.
The internal structure of Earth’s ice is a cosmological oddity. Its molecules are arranged in geometric structures, usually hexagons that repeat each other. Ice on Earth forms this way due to the temperature and pressure of the our planet: water here freezes slowly, and this allows its molecules to arrange themselves into crystals.
But ice that forms in space is different because of
