A clock built by a team led by researchers at the National Institute of Standards and Technology (NIST) has been estimated to be 41 percent more accurate than the previous timekeeping record holder.

The world's most accurate clock – so precise that it would take 10 billion years for it to deviate by one second – has gone ...

An NIST physicist holds the newly modified ion trap for the aluminum ion clock. By modifying the trap, the aluminum ion and its magnesium ion partner could 'tick' unperturbed. Optical atomic clocks ...

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

Accuracy may come at a cost. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. What’s the price of an accurate clock? Entropy, a new study has ...

It would take 15 billion years for the clock that occupies Jun Ye’s basement lab at the University of Colorado to lose a second. This undated handout photo obtained September 8, 2021 shows ...

An extremely cold gas of strontium atoms is trapped in a web of light known as an optical lattice. The atoms are held in an ultrahigh-vacuum environment, which means there is almost no air or other ...

A new experiment shows that the more energy consumed by a clock, the more accurate its timekeeping. Clocks pervade every aspect of life, from the atomic clocks that underlie satellite navigation to ...

The most accurate clock in space launches within days and will begin building a highly synchronised network out of the best clocks on Earth. But the project, decades in preparation, will only operate ...

Travellers have relied on accurate timekeeping for navigation since the development of the marine chronometer in the eighteenth century. Galileo, Europe’s twenty-first century navigation system, also ...
