More accurate strontium-based atomic clocks are possible – and accurate to one second every 40 billion years – by emitting radiation in the visible, rather than microwave, spectrum.

The theory was developed by Neils Bohr's great-grandson. The use of a special type of atom could make even the most advanced atomic clocks more precise, scientists believe. If confirmed, this ...

A recent breakthrough has paved the way for timekeeping even more precise than the measurements performed by atomic clocks.

The next generation of atomic clocks "ticks" with the frequency of a laser. This is about 100,000 times faster than the microwave frequencies of the cesium clocks which are generating the second ...

The clock, which utilizes quantum entanglement of atoms and a different element than most atomic clocks rely on, could be dramatically more accurate over long periods of time than current models.

Atomic clocks built at the official U.S. timekeeping laboratory tick with record-breaking regularity, scientists said — marking an advance that may someday allow researchers to perform new tests ...

Atomic clocks base their timekeeping on measuring the exact vibrations of individual atoms to designate a single second.

A new ultra-precise atomic clock outperforms existing microwave clocks in time-keeping and sturdiness under real-world conditions. The clock, made by a team of researchers from the California, ...

Atomic clocks use these frequencies — specifically, absorbing and emitting photons at regular intervals to keep time. They are the most accurate clock we have to measure time in seconds.

Scientists working with an early version of the cesium atomic clock in 1959. Leap seconds have been used to keep atomic time and astronomical time in sync.

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, stock trading ... and space navigation?Today on ...

New clock just dropped, but it’ll only drop a second every 30 billion years while in operation. That’s right: It’s the most precise, accurate clock yet built. The timekeeping device was ...
