By Katie Polglase, Gianluca Mezzofiore, Christian Edwards and Henry Zeris, CNN (CNN) — Israel launched a wave of unprecedented strikes on Iran shortly before sunrise Friday morning, hitting key sites ...

They concluded that the performance of their OFD system is sufficient to support an atomic reference with stability better than the commercially available cesium clock that has frequency ...

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.

At the heart of this change is a new kind of atomic clock that uses light instead of microwaves. This shift means timekeeping could become 1,000 times more accurate than today's standards.

Adelaide-based QuantX Labs plans to launch a key subsystem of its optical atomic clock into space to enhance position, navigation, and timing (PNT) capabilities.

The advantage of a radio-controlled clock that receives the time signal from WWVB is that you never have to set it again. Whether it’s a little digital job on your desk, or some big analog wa… ...

The Doomsday Clock is now at 89 seconds to midnight and we’ve never been closer to annihilation. Here’s everything you need to know about the recent announcement, the origins of the clock, and ...

The Bulletin of the Atomic Scientists set the clock to 89 seconds before midnight — the theoretical point of annihilation. That is one second closer than it was set last year.

The Bulletin of the Atomic Scientists set the clock to 89 seconds before midnight — the theoretical point of annihilation. That is one second closer than it was set last year.

Atomic scientists moved their "Doomsday Clock" closer to midnight than ever before, citing Russian nuclear threats amid its invasion of Ukraine and other factors underlying the risks of global ...

Atomic scientists on Tuesday moved their "Doomsday Clock" closer to midnight than ever before, citing Russian nuclear threats amid its invasion of Ukraine, tensions in other world hot spots, military ...

On a low platform, against the wall, sat a large metal frame. ... For another $345 a month, Nist will throw in a rubidium oscillator, a tiny atomic clock.
