For all our telescopes and colliders, dark matter has remained an elusive ghost for the better part of a century. It ...

CHICAGO -- The Doomsday Clock has been set to its closest time to midnight in its history, the Bulletin of the Atomic Scientists announced Tuesday. The clock has now been set to 90 seconds to midnight ...

After 78 years, the Doomsday Clock has been set closer than it has ever been. As a global society, we are now only 89 seconds to midnight after scientists moved the clock’s hand one second closer to ...

The current methods for attitude determination are Star Trackers, sun sensors, magnetometers, and gyroscopes. We would like ...

BRAUNSCHWEIG, Germany — Time measurement is entering a new era. The next generation of atomic clocks uses laser light instead of microwaves to track time, oscillating about 100,000 times faster than ...

DENVER (KDVR) — It is said that time is relative and passes differently depending on an observer’s relative motion and gravitational potential. Although some would argue time is a construct, it does ...

This research suggests that even chaotic, unpredictable phenomena, like waves on a shore or the beating of a heart, can be ...

This particular clock is technically an ion clock, which is different from the more common atomic clocks that are based on measuring the resonant frequencies of a single cesium atom to regulate time ...

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, the ...

The field of optical atomic clocks, in combination with ultracold atoms, has transformed precision timekeeping and metrology. By utilising laser-cooled atoms confined in optical lattices, researchers ...

Christophe Salomon, has been awarded the 2025 Balzan Prize for his research on ultra-cold atoms and the development of ...
