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 ...

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 ...

“Because visible light has a frequency that is five orders of magnitude higher than microwaves, optical clocks are about 100 times more accurate than the current standard of caesium atomic ...

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

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 ...

It keeps such great time by periodically syncing with the atomic clock in Mainflingen, Germany. The core of the project is an ATMega328 which uses the new DCF77 library for decoding the signal ...

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.

This breakthrough could multiply the precision of current GPS systems ... Traditional atomic clocks, although precise, use microwaves to measure time. Optical atomic clocks, on the other hand ...

Israel’s seasonal time change is set ... clocks move forward one hour—jumping from 2:00 a.m. to 3:00 a.m. The National Physics Laboratory determines Israel’s official time using four atomic ...

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 ...
