The European Space Agency has launched two atomic clocks on a SpaceX rocket to the ISS to test Einstein's theory of ...

The Atomic Clock Ensemble in Space (ACES) is a European Space Agency (ESA) mission that will generate a time signal with unprecedented accuracy and then transmit it via laser to nine ground ...

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 ...

Optical atomic clocks, capable of measuring time with fractional ... for microscopic control over individual atoms, offering ...

With access to a 10-MHz timebase from a cesium fountain atomic clock — no less a clock than the one that’s used to define the SI second, by the way — [Daniel] looked for ways to sync the ...

Atomic clocks keep getting smaller ... The design is based on Microchip’s unique Evacuated Miniature Crystal Oscillator (EMXO) technology that’s integrated into the CSAC, enabling the model ...

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 ...

How do we know Einstein had it right? One experiment in the 1970s provided some pretty strong evidence: Atomic clocks are extremely accurate clocks that can measure tiny amounts of time ...

Atomic clocks are timekeeping devices that use the vibrations of atoms (commonly cesium, rubidium, or hydrogen) as their ...

Quantum clock maker QuantX Labs is preparing to launch a key component of its optical atomic clock into space for the first ...
