How ultraprecise ‘nuclear clocks’ could transform timekeeping

Physicists are getting closer to creating a long-sought ‘nuclear clock’. This device would keep time by measuring energy transitions in the nuclei of atoms and could become the ...

A New Kind of Atomic Clock Could Redefine the Second

To explore deep space, we'll need better clocks. Here's why

Every single day, humans rely on hundreds of hidden clocks. GPS location, Internet stability, stock trading, power grid management ... all rely on atomic clocks in order to work. Many of those clocks ...

Scientists Built Tiny, Portable Atomic Clocks—and Naturally, They’re Headed for Drones

This breakthrough in precision timing is about the size of your fingernail and only loses one second every 30,000 years.

Redefining the second: Optical atomic clock achieves record accuracy in comparison measurement

The next generation of atomic clocks "ticks" with the frequency of a laser. This is about 100,000 times faster than the microwave frequencies of the cesium clocks which are generating the second at ...

A new atomic clock in space could help us measure elevations on Earth

The European Space Agency’s ACES mission could ultimately pave the way for a global network of atomic clocks that make these measurements far more accurate. In 2003, engineers from Germany and ...

Explainer: What is an atomic clock and why it is crucial for navigation satellites

Launched aboard the PSLV–C32, ISRO’s workhorse, and successfully placed into geosynchronous orbit on March 10, 2016, it was the sixth satellite in the IRNSS series ...
