RealFeedApp Rubidium atoms hit 9.7 trillionths of a degree
In China's Tiangong space station, a team cooled a cloud of 20,000 rubidium atoms to an energy equivalent of just 9.7 trillionths of a degree above absolute zero. This result surpassed the 2021 record of 38 picokelvin set by previous researchers.

- What they did
- Researchers on China's Tiangong space station cooled a cloud of about 20,000 rubidium atoms to within 9.7 trillionths of a degree above absolute zero, breaking the previous record by four times.
- Why it matters
- This provides future researchers with a longer observation window to study physics at such extremely low temperatures, advancing the field of thermodynamics.
