A new Air Force project aims to replace vulnerable satellite signals with atomic clock technology for next-generation drone ...

The Air Force Research Laboratory seeks input about ways groups of drones can function together without traditional means of ...

Nucleons, which include protons and neutrons, are the composite particles that make up atomic nuclei. While these particles have been widely studied in the past, their internal structure has not yet ...

Aug. 5 might be one of the shortest days of the year: Here's why The change is imperceptible but Earth can rotate over a millisecond faster.

There's a new record holder for the most accurate clock in the world. Researchers at the National Institute of Standards and Technology (NIST) have improved their atomic clock based on a trapped ...

By using paired, offset optical combs and RF electronics, researchers devised a unique atomic-clock architecture.

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.

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.

A new atomic clock is one of the world’s best timekeepers, researchers say — and after years of development, the “fountain”-style clock is now in use helping keep official U.S. time.

At the heart of this change is a new kind of atomic clock that uses light instead of microwaves. This shift means timekeeping could become 1,000 times more accurate than today's standards.

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.
