Computer illustration of a supersolid made from two different types of ultracold boson atoms (red and green). The atoms are arranged in a regularly repeating pattern, like a solid, but can also move without friction and without losing energy, like a superfluid. Such properties only occur at ultracold temperatures close to 0 Kelvin. The yellow area represents the electrical forces that the atoms feel, which vary in a regular pattern. The density of the atoms (represented by their opacity) also varies in a periodic fashion.
