9.7 picokelvin: China Space Station creates artificial matter a hundred billion times colder than deep space, setting a world record

Chinese scientists aboard the China Space Station have used all-optical trap cooling to chill a cloud of rubidium atoms to 9.7 picokelvin, 14 orders of magnitude below room temperature and nearly 300 billion times colder than the background temperature of deep space, breaking the previous record of 38 picokelvin set in 2021 and making it the coldest known artificial matter.
