NIST traced the problem to its Boulder, Colorado campus, where a prolonged utility power outage disrupted operations. The ...

The National Institute of Standards and Technology recently warned that an atomic clock device installed at its Boulder campus had failed due to a prolonged power ...

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

For decades, atomic clocks have provided the most stable means of timekeeping. They measure time by oscillating in step with ...

A destructive windstorm disrupted the power supply to more than a dozen atomic clocks that keep official time in the United ...

A power outage in Colorado slowed down the time set by atomic clocks at the NIST laboratory, which accounted for the official ...

At this point, atomic clocks are old news. They’ve been quietly keeping our world on schedule for decades now, and have been through several iterations with each generation gaining more accuracy. They ...

Atomic clocks will only see a loss of 1 second in accuracy over a period of 10 million years. They are used in multiple ways, including the GPS in your car. Now researchers have found a way to bypass ...

The emission of photons by excited nuclei has been explored for timekeeping and sensing, but nuclear processes that eject electrons offer practical advantages. Electrons in atoms can exist only in ...
