An atomic clock that could transform deep-space travel has successfully completed its first test run in space. NASA’s Deep Space Atomic Clock, which launched on a satellite in June 2019, outperformed ...

A team of physicists at the University of Toronto developed a clock they say may be the most accurate on the planet.

Today’s state-of-the-art optical clocks offer accuracy to 18 decimal places, which is roughly equivalent to measuring the ...

Atoms are the world’s most precise timekeepers – so much so that the second is defined as exactly 9 192 631 770 ticks of a caesium-based atomic clock. Commercially-available versions of these ...

A new atomic clock unveiled Thursday (April 3) is three times more accurate than the one previously used to keep official time in the United States, making it the most precise timekeeper yet developed ...

Knowing what time it is down to the very last sliver of a second is easy — but only if you happen to have an atomic clock in your pocket. Unfortunately, most such devices wouldn't fit. In fact, there ...

Scientists have developed the most precise and accurate atomic clock to date – if you ran it for twice the current age of the universe, it would only be off by one second. This could not only improve ...

Atomic clocks. They almost sound like something out of science fiction, or an experiment confined to some elite physics lab, but in reality, they’ve been around since the 1950s in one form or another.
