The National Institute of Standards and Technology's new cesium fountain clock is one of the most precise atomic clocks ever ...

Marvel’s Time Variance Authority (TVA) would probably call dibs on this atomic clock if they could! The NIST-F4 atomic clock, ...

Clocks on Earth are ticking a bit more regularly thanks to NIST-F4, a new atomic clock at the National Institute of Standards ...

The way time is measured is on the edge of a historic upgrade. At the heart of this change is a new kind of atomic clock that ...

Atomic clocks record time using microwaves at a frequency matched to electron transitions in certain atoms. They are the basis upon which a second is defined. But there is a new kid on the block ...

So steady are these oscillations that atomic clocks keep better time than the spinning earth itself The "pendulums" which regulate them are the vibrating parts of atoms or molecules.

This technology, called the 'microcomb chip,' could make optical atomic clocks, the most precise timekeepers in the world, compact enough for everyday use. Credit: Kaiyi Wu This breakthrough could ...

The Atomic Clock Ensemble in Space (ACES), ESA's state-of-the-art timekeeping facility, has been successfully installed on the International Space Station, marking the start of a new chapter in ...

The Atomic Clock Ensemble in Space (ACES) is a European Space Agency (ESA) mission that will generate a time signal with unprecedented accuracy and then transmit it via laser to nine ground ...
