World's first thorium-229 nuclear clock shows potential for ultra-precise timekeeping and fundamental physics tests.

Two independent research teams have achieved a longstanding goal in physics: building a working nuclear clock. The devices, ...

An NIST physicist holds the newly modified ion trap for the aluminum ion clock. By modifying the trap, the aluminum ion and its magnesium ion partner could 'tick' unperturbed. Optical atomic clocks ...

There's a new record holder for the most accurate clock in the world. Researchers at the National Institute of Standards and Technology (NIST) have improved their atomic clock based on a trapped ...

Researchers from the University of Science and Technology of China have achieved a major breakthrough in optical clock technology, developing a strontium optical lattice clock with stability and ...

When it comes to navigation in outer space, keeping precise time is incredibly important, that's why NASA needs to use ...

At this point, atomic clocks are old news. They’ve been quietly keeping our world on schedule for decades now, and have been through several iterations with each generation gaining more accuracy. They ...

The way time is measured is on the edge of a historic upgrade. At the heart of this change is a new kind of atomic clock that uses light instead of microwaves. This shift means timekeeping could ...

As if timekeeping in the U.S. wasn’t already pretty accurate, the U.S. Department of Commerce’s National Institute of Standards and Technology (NIST) just declared a new atomic clock, the NIST-F2, to ...

This feature is only available to members. Join now for full online access. Years ago, the world's most complicated clock was displayed for the first time in the town hall in Copenhagen, Denmark. It ...
