Earlier orbital cold-atom experiment on the International Space Station

A cloud of rubidium atoms inside China's space station has been cooled to an equivalent temperature of 9.7 picokelvins, about 9.7 trillionths of a degree above absolute zero. That is roughly four times colder than the previous record of 38 picokelvins, set by a German team in 2021.
