NASA and SpaceX just launched a major resupply mission to the International Space Station, to deliver nearly 7,000 pounds of cargo—including food, equipment, and high-tech experiments. From robotic ...

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

ACES will gather ultra-precise data across at least ten observation windows, each lasting about 25 days during the ...

Testing Einstein’s relativity, measuring fundamental constants, and even searching for dark matter are all on the cards ...

The atomic clock payload to be installed on the ISS's Columbus module, aims to push the boundaries of precision timekeeping ...

On Tuesday, Ukrainian President Volodymyr Zelensky posted a video and a statement on the social media platform X saying that Ukraine had arrested two Chinese nationals who, he said, were fighting on ...

Phillips chats about quirky quantum phenomena such as entanglement and superposition and explains how they are exploited in atomic clocks and quantum computing. He also looks to the future of quantum ...

Atomic clocks record time using microwaves to measure the frequency of quantum vibrations of electrons. They are the basis upon which a second is defined. But there’s a new kid on the block ...

Atomic clocks have long been the gold standard for measuring time and frequency. Among them, optical clocks—using atoms like strontium or aluminum—have reached staggering levels of accuracy ...

In order to conduct the experiment, the pair loaded four ultra-precise atomic clocks onto two different aeroplanes flying in different directions. The clocks were then compared to another one on ...
