The new clock is so reliable that it would be off by less than a second if it had started running 100 million years ago, ...

The National Institute of Standards and Technology's new cesium fountain clock is one of the most precise atomic clocks ever ...

The way time is measured is on the edge of a historic upgrade. At the heart of this change is a new kind of atomic clock that ...

Clocks on Earth are ticking a bit more regularly thanks to NIST-F4, a new atomic clock at the National Institute of Standards and Technology (NIST) campus in Boulder, Colorado. NIST-F4 measures an ...

Whether you find yourself glancing at a clock on the wall or checking your phone, the time you constantly see is the product of a meticulous system upheld by the world’s timekeepers. In the U.S., a ...

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.

DENVER (KDVR) — It is said that time is relative and passes differently depending on an observer’s relative motion and gravitational potential. Although some would argue time is a construct ...

Atomic Digital Clock Auto Set (no back light) - Using radio frequencies broadcast from NIST’s Colorado , the clock will automatically set to the correct time. Automatically adjusts to Daylight ...

Clocks on Earth are ticking a bit more regularly thanks to NIST-F4, a new atomic clock at the US National Institute of Standards and Technology (NIST) campus in Boulder, Colorado. NIST has also ...

The European Space Agency (ESA) has launched one of its most precise science experiments to date — the Atomic Clock Ensemble in Space (ACES)—to the International Space Station (ISS).

On Monday, the European Space Agency (ESA) launched the ACES set of atomic clocks. It will be docked to the International Space Station (ISS) to measure the effect of gravity on the passage of time.
