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 ...

The next generation of atomic clocks uses laser light instead of microwaves to track time, oscillating about 100,000 times faster than current timekeeping standards. Now, scientists at The ...

On Monday, the European Space Agency (ESA) launched the ACES set of atomic clocks to measure the effect of gravity on the passage of time.

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 ...

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 ...
