Most clocks, from wristwatches to the systems that run GPS and the internet, work by tracking regular, repeating motions. To build a clock, you need something that ticks in a perfectly repeatable way.

Adelaide University researchers have successfully tested a new type of portable atomic clock at sea for the first time, using technology that could help power the next generation of navigation, ...

Denver, Colorado | Physicists are getting closer to creating a long-sought ‘nuclear clock’. This device would keep time by measuring energy transitions in the nuclei of atoms and could become the most ...

India's indigenous satellite navigation system, Navigation with Indian Constellation (NavIC), is facing scrutiny after reports that an atomic clock onboard one of its satellites has stopped ...

One of India’s four navigation satellites has failed, a setback for the NAVIC network. Satellite IRNSS-1F was lost after its atomic clock stopped functioning. Only three satellites — IRNSS-1B, ...

AURORA, Colorado—Lockheed Martin and the U.S. Space Force are testing several new technologies aboard the next GPS III satellite, including a new digital atomic clock. Current GPS satellites carry a ...

Time is almost up on the way we track each second of the day, with optical atomic clocks set to redefine the way the world measures one second in the near future. Researchers from Adelaide University ...

The Bulletin of Atomic Scientists has set the Doomsday Clock to 85 seconds to midnight. It is the closest the clock has ever been to midnight in its history. The Bulletin of Atomic Scientists said ...

Atomic scientists set their "Doomsday Clock" on Tuesday closer than ever to midnight, citing aggressive behavior by nuclear powers Russia, China and the United States, fraying nuclear arms control, ...
