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

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

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

The European Space Agency has launched two atomic clocks on a SpaceX rocket to the ISS to test Einstein's theory of ...

An atomic clock research team from the National Time Service Center of the Chinese Academy of Sciences has proposed and ...

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 ...

NASA's SpaceX 32nd commercial resupply services mission, scheduled to lift off from the agency's Kennedy Space Center in ...

The results of this research were published in Nature Photonics. Traditional atomic clocks, although precise, use microwaves to measure time. Optical atomic clocks, on the other hand, use laser light ...

provide them with the exact time and date thanks to accurate atomic clocks and the clever Network Time Protocol (NTP). But it wasn’t always like this: back in the 1990s when many computers didn ...
