From space, the Atomic Clock Ensemble in Space will link to some of the most accurate clocks on Earth to create a synchronized network, which will support tests of fundamental physics.

A wake-up call is sounded in the latest reports on the extent of damage America meted out to Iran’s nuclear program ...

America's official time is kept at a government laboratory in Boulder, Colo., and according to the clock at the entrance, I was seven minutes behind schedule. I rush across the campus of the ...

Atomic clocks operate by measuring the energy jumps of electrons between different energy levels when exposed to specific laser ... and IMRA America Inc. Journal Reference: Zhang, C., et al.

There are hundreds of atomic clocks in orbit right now, perched on satellites all over Earth. We depend on them for GPS location, Internet timing,... To explore deep space, we'll need better ...

Atomic clocks that excite the nucleus of thorium-229 embedded in a transparent crystal when hit by a laser beam could yield the most accurate measurements ever of time and gravity, and even ...

Many modern atomic clocks use oscillations of strontium atoms rather than cesium to measure time; the most precise of these is accurate to within 1/15,000,000,000 of a second. This means that ...

There are 21 clocks like Elvis spread across the campus, and they're all used to set America's time. It's an incredible system that's accurate to better than a trillionth of a second.
