Due to the power outage, time (very) briefly stood still at the NIST Internet Time Service facility in Boulder.

Time appeared to skip a beat last week when some of the world’s most accurate clocks were affected by a wind-induced power ...

A collaboration between researchers in the US and Germany has made a major breakthrough in optical nuclear clocks, achieving laser-based excitation of Thoria-229 in a non-transparent host material.

Officials said the error is likely too minute for the general public to clock it, but it could affect applications such as critical infrastructure, telecommunications and GPS signals.

From freeze-dried strawberries to memory foam and scratch-resistant glasses, space exploration is the force behind a myriad of life-changing innovations. Now it’s time for a terrestrial innovation to ...

NIST restored the precision of its atomic clocks after a power outage caused by a power outage disrupted operations. Discover ...

The National Institute of Standards and Technology’s Internet Time Service Facility in Boulder lost power Wednesday afternoon ...

The goal of the Defense Advanced Research Projects Agency’s (DARPA’s) Chip-Scale Atomic Clock (CSAC) program is to provide warfighters with enhanced radio communications and jam-resistant navigation ...

This is an atomic clock that uses the predictable frequency of ytterbium atoms absorbing and emitting light to tell time. A new experiment paired a ytterbium-based atomic clock with two others that ...

Atomic clocks are the most accurate timekeepers we have, losing only seconds across billions of years. But apparently that’s not accurate enough – nuclear clocks could steal their thunder, speeding up ...

We normally think of atomic clocks as the gold standard in timekeeping. The very definition of a second — in modern times, at least — is 9,192,631,770 periods of the radiation corresponding to the ...

It was 2:30 in the morning when astronautical engineer Todd Ely watched as a little atomic clock—the size of a four-slice toaster—was launched into space on a satellite attached to one of the most ...
