The world spins faster for 3 days straight in July and August, prompting experts to monitor Earth's changing rotation.

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.

According to scientists at NIST in Boulder, their newest atomic clock, the NIST-F4, will help track time more precisely and help put global time on a more accurate frequency.

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.

NIST scientists have published results establishing a new atomic clock, NIST-F4, as one of the world’s most accurate timekeepers, priming the clock to be recognized as a primary frequency ...
