A new atomic clock is one of the world’s best timekeepers, researchers say — and after years of development, the “fountain”-style clock is now in use helping keep official U.S. time. Known ...

If an atomic clock fell out of sync with a nuclear clock, for example, some change in the underlying physics might be responsible. Only time will tell. Curious about the world?

That's why atomic physicists at NASA want to build a more precise, more autonomous atomic clock. Sponsor Message. The team hopes a prototype will be ready by late 2025. Related reading: ...

Picture a clock ticking so steadily that it doesn’t lose a second, even after running for 1 billion years. Scientists are now closer than ever to realizing that level of timekeeping precision ...

On a campus in Boulder, Colorado, time just became a little more exact. Inside the National Institute of Standards and Technology, or NIST, a new atomic clock named NIST-F4 has begun to tick ...

The most precise and accurate atomic clock in the world, the ultracold strontium clock at JILA in Boulder, is like a stopwatch that can count the billionths of a nanosecond, or 18 digits past the ...

Atomic scientists moved their "Doomsday Clock" closer to midnight than ever before, citing Russian nuclear threats amid its invasion of Ukraine and other factors underlying the risks of global ...

A clock network would allow geodesists to compare the ticking of clocks all over the world. They could then use the variations in time to map Earth’s gravitational field much more precisely, and ...
