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 ...

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 ...

This technology, called the 'microcomb chip,' could make optical atomic clocks, the most precise timekeepers in the world, compact enough for everyday use. Credit: Kaiyi Wu This breakthrough could ...

China will soon send a trio of atomic clocks to its Tiangong space station, to establish a space-based timekeeping system of exceptional accuracy. The clocks can work together to measure time with ...

GPS satellites are equipped with atomic clocks that deliver precise time. In military operations that guide missiles and involve time-sensitive cyber warfare, time is gold. Recently, China ...

When the clock was first depicted on the June 1947 issue—set at seven minutes to midnight—the editors were concerned solely with the likelihood that atomic bombs would soon rain down on the ...

Researchers demonstrated a new optical atomic clock that uses a single ... frequency comb laser acts as both the clock's pendulum, or ticking mechanism, and as the gearwork that tracks time." ...

WASHINGTON — Researchers have demonstrated a new optical atomic clock that uses ... comb laser acts as both the clock’s pendulum, or ticking mechanism, and as the gearwork that tracks time.” ...

FOR THE discerning timekeeper, only an atomic clock will do. Whereas the best quartz timepieces will lose a millisecond every six weeks, an atomic clock might not lose a thousandth of one in a decade.

Such a device would greatly surpass the capabilities of atomic clocks, which define the span of a second through controlled energy jumps in atoms’ electrons and are currently the pinnacle of ...

Atomic clocks are our most accurate timekeepers, losing only seconds across billions of years. But nuclear clocks could steal their thunder, speeding up GPS and the internet.

have developed a clock that is not a normal clock but a light-based atomic clock that is the world's most precise and sturdy clock ever. This clock is capable of detecting gravity at a ...
