Chinese scientists aboard the Tiangong space station have cooled rubidium atoms to 9.7 picokelvins, setting a new world record for the coldest man-made matter. This achievement, announced on November 6, 2026, allows researchers to explore quantum states of matter, specifically Bose-Einstein condensates. The experiment utilized laser-based traps to contain approximately 20,000 rubidium atoms in a microgravity environment, which enhances cooling effectiveness compared to Earth. Previous records included 38 picokelvins achieved in Germany and 52 picokelvins by NASA. The findings will be published in the journal Science, providing insights into fundamental physical laws and exotic states of matter. This breakthrough opens new avenues for quantum research and understanding the universe.
