Strontium atomic clock accurate to the second -- over 15 billion years. ScienceDaily . Retrieved June 2, 2025 from www.sciencedaily.com / releases / 2015 / 04 / 150421132031.htm ...

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.

By comparing optical clocks in six different countries, researchers have taken a major step toward establishing a new global ...

PORTLAND, Ore. — A candidate to be the next-generation atomic clock is based on the heavy metal strontium and uses a laser lattice to suspend super-cooled atoms. The result was a 430-THz time ...

Scientists from the University of Colorado Boulder have created an atomic clock using lasers and strontium atoms that’s incredibly accurate—only losing one second every 40 billion years.

NASA scientists are moving on from typical atomic clocks and using optical light and strontium atoms to build a new future.

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 ...

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 ...

The team also compared their UV frequency to the optical frequency of another of the world’s most accurate strontium-based atomic clocks to establish the first “direct frequency link ...

"Many recent atomic clocks, ours included ... which highlighted the potential of building precise optical lattice clocks using strontium atoms. "A typical clock has three components: an oscillator ...

Atomic clocks use these frequencies — specifically ... The aluminum-ion and ytterbium clocks were kept in a lab in Boulder, Colorado. The strontium clock was placed about a mile away in a ...
