For decades, atomic clocks have provided the most stable means of timekeeping. They measure time by oscillating in step with ...

A collaboration between researchers in the US and Germany has made a major breakthrough in optical nuclear clocks, achieving ...

Nuclear clocks are a technology researchers have been working toward for decades. New research in theoretical physics brings them closer to reality.

Atomic clocks will only see a loss of 1 second in accuracy over a period of 10 million years. They are used in multiple ways, including the GPS in your car. Now researchers have found a way to bypass ...

At this point, atomic clocks are old news. They’ve been quietly keeping our world on schedule for decades now, and have been through several iterations with each generation gaining more accuracy. They ...

A research team at VTT MIKES has set a new record in optical-clock absolute frequency measurements using a strontium single-ion clock with exceptionally low uncertainty and high uptime.

The white pickup truck pulls up to a decommissioned space observatory on top of Mount Blue Sky, one of Colorado’s famous “14ers,” mountains that reach more than 14,000 feet high. The scene is stark on ...
