ACES will gather ultra-precise data across at least ten observation windows, each lasting about 25 days during the ...

The atomic clock payload to be installed on the ISS's Columbus module, aims to push the boundaries of precision timekeeping ...

The clock hands are set by the Bulletin of the Atomic Scientists, a group formed by Manhattan Project scientists at the University of Chicago who helped build the atomic bomb but protested using it ...

Atomic clocks record time using microwaves at a frequency matched to electron transitions in certain atoms. They are the basis upon which a second is defined. But there is a new kid on the block ...

Modern timekeeping relies on the accuracy of atomic clocks, which revolutionized timekeeping by using the quantum behavior of atoms to measure time. Discover how these incredibly precise clocks ...

In 2001, Japanese physicist Hidetoshi Katori proposed a new type of atomic clock that only loses a second every 30 billion years, a period longer than the current age of the universe. The ...

ESA's Atomic Clock Ensemble in Space (ACES ... of ESA's Columbus module on the International Space Station, measuring time from orbit with unprecedented precision. Earlier this month, ACES ...

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 ...
