Space Station Experiment Reaches Ultracold Milestone

Space Station Experiment Reaches Ultracold Milestone

The International Space Station is officially home to the coolest experiment in space.

NASA's Cold Atom Laboratory (CAL) was installed in the station's U.S. science lab in late May and is now producing clouds of ultracold atoms known as Bose-Einstein condensates. These "BECs" reach temperatures just above absolute zero, the point at which atoms should theoretically stop moving entirely. This is the first time BECs have ever been produced in orbit.
