China's Space Station Achieves Record Atomic Cooling for Quantum Research

Chinese scientists on their space station cooled rubidium atoms to 9.7 trillionths of a degree above absolute zero, setting a new record. This ultracold environment allowed for seven-second observation of atomic expansion, significantly extending the window for quantum experiments in microgravity. The achievement enhances precision measurements and deepens understanding of quantum behavior, with findings published in Science.
