A new atomic clock is one of the world’s best timekeepers, researchers say — and after years of development, the “fountain”-style clock is now in use helping keep official U.S. time. Known ...

Happy birthday, caesium clock. Now move over. As the atomic clock used to define time itself turns 60, tests are set to begin on a new generation of clocks that are designed to give the caesium ...

Caesium atomic-fountain clocks are used to set national time standards at NIST, at the Paris Observatory and elsewhere. The caesium fountain clock has an accuracy of about three parts in 10 ...

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 wall ...

A newly-designed atomic clock uses entangled atoms to keep time even more precisely than its state-of-the-art counterparts. The design could help scientists detect dark matter and study gravity's ...

NASA is set to launch an incredible new atomic clock into orbit on a Falcon Heavy tomorrow (June 24) in a technology demonstration mission that could transform the way humans explore space.. The ...

In 2020, the Bulletin set the Doomsday Clock at 100 seconds to midnight, the first time it had moved within the two-minute mark. For the next two years, the hands were left unchanged .

The Doomsday Clock was set at 90 seconds to midnight, due largely but not exclusively to Russia’s invasion of Ukraine and the increased risk of nuclear escalation. The new Clock time was also ...

This year, the clock will be updated on Tuesday Jan. 23 at 10:00 am EST in Washington, D.C. The last announcement in January 2023 came before the beginning of the Israel-Hamas war but amid nuclear ...
