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 ...

Scientists are exploring a new type of optical atomic clock based on ytterbium-173 ions that could help define the future ...

Nuclear clocks are the next big thing in ultra-precise timekeeping. Recent publications in the journal Nature propose a new method and new technology to build the clocks. Timekeeping has become more ...

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

This is the third time that the clock has been moved closer to midnight in the past five years. “Every second counts, and we ...

To find out how clock accuracy is verified and which reference is used for comparison, we visited the Belarusian State Institute of Metrology (BelGIM), where most of the national standards are kept.

Researchers from Los Angeles, Munich, and Mainz open new avenues for nucleus-based quantum technologies A research team from the University of California Los Angeles (UCLA), Ludwig Maximilian ...

This month, the Bulletin of the Atomic Scientists at the University of Chicago is scheduled to announce whether the hands of its famous Doomsday Clock will move closer to midnight. It feels like a ...

For centuries, time was tied to Earth’s rotation, with a second defined as a fraction of a full day. But inconsistencies in the planet’s spin made that system unreliable for scientific use. Since 1967 ...

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 ...
