On November 6, the Chinese Academy of Sciences announced that Chinese scientists have achieved a new world record for the lowest temperature ever attained by humans. Using the all-optical trap cooling technology in the ultra-cold atom physics experiment cabinet aboard China's space station, they cooled a cloud of rubidium atoms to an equivalent temperature of 9.7 picokelvins—14 orders of magnitude lower than room temperature—and maintained continuous observation for 7 seconds. The achievement was led, demonstrated, managed, and integrated by the Technology and Engineering Center for Space Utilization of the Chinese Academy of Sciences, with joint contributions from Peking University and the Shanghai Institute of Optics and Fine Mechanics of the Chinese Academy of Sciences. The findings were published in the international academic journal Science.
