Clocks on Earth are ticking a bit more regularly thanks to NIST-F4, a new atomic clock at the National Institute of Standards ...

An alternative periodic table of elements focusing on highly charged ions reveals new science that could support the quest ...

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

NASA's SpaceX 32nd commercial resupply services mission, scheduled to lift off from the agency's Kennedy Space Center in ...

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 ...

The results of this research were published in Nature Photonics. Traditional atomic clocks, although precise, use microwaves to measure time. Optical atomic clocks, on the other hand, use laser light ...

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 ...
