New type of atomic clock is so accurate it will be less than a tenth of a second out after 14 BILLION years and could help scientists study gravity's effect on time Atomic clocks work by measuring ...

They're called hydrogen masers, and they are extremely important atomic clocks. Along with around 400 others, placed all around the globe, they help the world define what time it is, right now ...

A grandfather clock, for instance, loses about 15 seconds a day – an eon in comparison to the accuracy achieved by our gold standard, atomic clocks. Invented 60 years ago, they work by bathing a ...

Forget the atomic clock! World's first NUCLEAR clock is unveiled – paving the way for ultraprecise timekeeping READ MORE: Scientist says a 'negative leap second' will be needed in 2029 ...

The crystal oscillator “offers phase noise at 10Hz [of] <-120 dBc/Hz and Allan deviation stability of <10 -11 at a 1s averaging time. The atomic clock provides initial accuracy of ±0.5ppb, frequency ...

World's largest clock comparison paves way for redefining second standard with optical atomic clocks by 2030.

NASA's new Deep Space Atomic Clock - designed to provide a GPS-like system for spacecraft - is up to 10 times more stable than existing space clocks, new research has found.

Designed to operate in a wider temperature range, it enables low phase noise and atomic clock stability in demanding conditions. Developers need ultra-clean timing devices for aerospace and defence ...
