Many modern atomic clocks use oscillations of strontium atoms rather than cesium to measure time; the most precise of these is accurate to within 1/15,000,000,000 of a second. This means that ...

Picture a clock ticking so steadily that it doesn’t lose a second, even after running for 1 billion years. Scientists are now closer than ever to realizing that level of timekeeping precision ...

Scientists have found that Earth is spinning slightly faster than normal, resulting in shorter days, though the reason ...

Traditional atomic clocks, although precise, use microwaves to measure time. Optical atomic clocks, on the other hand, use laser light for even greater precision.

The researchers said a nuclear clock would have major advantages for clock precision over current technology. Atomic clocks measure time by tuning laser light to frequencies that cause electrons ...

Atomic clocks are the world’s most precise timekeeping devices, and they are essential to staples of modern life such as global positioning systems, telecommunications and data centres. The most ...

The newly unveiled nuclear clock isn’t more precise than today’s best atomic clocks, but Schumm said his team should overtake those timekeeping devices in a few years. “The first cars weren ...

From space, the Atomic Clock Ensemble in Space will link to some of the most accurate clocks on Earth to create a synchronized network, which will support tests of fundamental physics.

Atomic clocks only deviate by one second in millions of years. Nevertheless, even more precise timepieces are sometimes needed for basic research. Researchers at the Vienna University of ...

The European Space Agency’s ACES mission could ultimately pave the way for a global network of atomic clocks that make these measurements far more accurate. In 2003, engineers from Germany and ...
