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

F4, the latest cesium fountain clock that now stands as one of the most accurate timekeepers in the entire world.

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

According to scientists at NIST in Boulder, their newest atomic clock, the NIST-F4, will help track time more precisely and ...

With access to a 10-MHz timebase from a cesium fountain atomic clock — no less a clock than the one that’s used to define the SI second, by the way — [Daniel] looked for ways to sync the ...

ESA's state-of-the-art timekeeping facility, has been successfully installed on the International Space Station, marking the ...

“Because visible light has a frequency that is five orders of magnitude higher than microwaves, optical clocks are about 100 times more accurate than the current standard of caesium atomic ...

The invention – called the optical lattice clock – is a thousand times more accurate than cesium atomic clocks used for international timekeeping and is a contender for redefining how long a ...
