ESA's Atomic Clock Ensemble in Space (ACES) has arrived at NASA's Kennedy Space Center in Florida, United States. This cutting-edge European experiment will test fundamental physics from the ...

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

A technological innovation could revolutionize the precision of navigation systems. A tiny device, shaped like a comb, promises to deliver unparalleled accuracy in the field ...

Adelaide-based QuantX Labs plans to launch a key subsystem of its optical atomic clock into space to enhance position, ...

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 Atomic Spectroscopy Group provides standardized measurements used across wide swaths of science and industry. The Trump administration plans to cut it.

With access to a 10-MHz timebase from a cesium fountain atomic clock — no less a clock than the one that’s used to define the SI second, by the way — [Daniel] looked for ways to sync the ...

En-route to nuclear clocks, researchers have found a resonant mode in thorium atom nuclei with a low temperature coefficient – nuclear oscillators are mooted initially as replacements for atomic ...
