Cold Atom Lab

iss057e106407 (11/20/2018) -- A view of the Cold Atom Lab (CAL) in the Destiny module aboard the International Space Station (ISS). The Cold Atom Laboratory (CAL) produces clouds of atoms that are chilled to about one ten billionth of a degree above absolute zero -- much colder than the average temperature of deep space. At these low temperatures, atoms have almost no motion, allowing scientists to study fundamental behaviors and quantum characteristics that are difficult or impossible to probe at higher temperatures
