Chinese Space Station Achieves New Record for Atomic Cooling in Microgravity

Chinese scientists aboard the China Space Station have cooled a cloud of rubidium atoms to an equivalent temperature of 9.7 trillionths of a degree above absolute zero, setting a new record. This ultracold atom physics experiment, conducted in the station's Mengtian laboratory module, allows for extended observation of quantum behavior and improved precision measurements in microgravity, which is crucial for advancing quantum phenomena studies and atom interferometry. The findings were published in the journal Science.
