The European Space Agency (ESA) has launched one of its most precise science experiments to date — the Atomic Clock Ensemble in Space (ACES)—to the International Space Station (ISS). This is no ...

Nuclear clocks are the next big thing in ultra-precise timekeeping. Recent publications in the journal Nature propose a new method and new technology to build the clocks. Timekeeping has become more ...

A team of researchers in Austria has recently demonstrated that the world’s first nuclear clock could help answer whether the fine-structure constant changes over time. The scientists from the Vienna ...

For decades, atomic clocks have provided the most stable means of timekeeping. They measure time by oscillating in step with the resonant frequency of atoms, a method so accurate that it serves as the ...
