Scientists Achieve Record-Breaking Low Temperature on China's Space Station, Paving the Way for New Physics Experiments
The record-low 9.7 picokelvin result could extend observation times for quantum experiments and improve space-based precision sensors, researchers said.
- On Friday, Researchers published in Science that they cooled rubidium atoms aboard Tiangong to 9.7 trillionths of a degree above absolute zero, setting a new record low.
- Gravity limits observation on Earth, but the microgravity environment allows Researchers to confine atoms more weakly and observe them for seven seconds, impossible on Earth where gravity would pull them down.
- Using The Cold Atom Physics Rack on Mengtian, the team surpassed records from Nasa's Cold Atom Lab on the International Space Station and a German drop tower.
- Wolfgang Ketterle, a 2001 Nobel laureate, called the achievement "an excellent starting point to advance atomic thermometry and precision measurements," validating the importance of space-based experiments.
- Future space-based atom interferometers could enable Researchers to track climate change, identify hidden minerals, and test Einstein's theory of gravity, advancing precision measurements.

Scientists achieve record-breaking low temperature on China's space station, paving the way for new physics experiments
Matter starts to behave differently at extremely low temperatures, creating conditions ideal for studying quantum physics and new states of matter. Now, researchers from China have achieved a new low-temperature record aboard their Tiangong space station. Their research, recently published in Science, might lead to a new generation of experiments in quantum physics and precision measurements in space.
The researchers achieved a temperature of 9.7 picokelnin, a state of extreme cold in which atoms almost freeze and exhibit quantum behaviors. The post On the threshold of absolute zero – Experiment on the Chinese space station broke a low temperature record appeared first on in.gr.
Chinese researchers cooled the ruby atoms at the Tiangun Space Station to record low temperatures. China's scientists brought a cloud of thousands of atoms of ruby to a temperature of less than 10 trillion degrees above absolute zero, breaking previous U.S. and German records, wrote South China Morning Post. According to the publication, this breakthrough would allow the creation of ultra-precision space sensors to search for hidden minerals, mo…
