The European Space Agency’s ACES mission could ultimately pave the way for a global network of atomic clocks that make these ...

The new clock is so reliable that it would be off by less than a second if it had started running 100 million years ago, ...

From space, the Atomic Clock Ensemble in Space will link to some of the most accurate clocks on Earth to create a ...

Clocks on Earth are ticking a bit more regularly thanks to NIST-F4, a new atomic clock at the National Institute of Standards and Technology (NIST) campus in Boulder, Colorado. NIST-F4 measures an ...

Whether you find yourself glancing at a clock on the wall or checking your phone, the time you constantly see is the product of a meticulous system upheld by the world’s timekeepers. In the U.S., a ...

Atomic Digital Clock Auto Set (no back light) - Using radio frequencies broadcast from NIST’s Colorado , the clock will automatically set to the correct time. Automatically adjusts to Daylight ...

At the heart of this change is a new kind of atomic clock that uses light instead of microwaves. This shift means timekeeping could become 1,000 times more accurate than today's standards.

DENVER (KDVR) — It is said that time is relative and passes differently depending on an observer’s relative motion and gravitational potential. Although some would argue time is a construct ...

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

An atomic clock research team from the National Time Service Center of the Chinese Academy of Sciences has proposed and implemented a compact optical clock based on quantum interference enhanced ...

Marvel’s Time Variance Authority (TVA) would probably call dibs on this atomic clock if they could! The NIST-F4 atomic clock, recently unveiled by the National Institute of Standards and Technology in ...
