For practical purposes, we say that one day—the time it takes for Earth to rotate once on its axis—equates to 24 hours. In ...

A few days ago, there was news that "the abolition of the leap second will be officially decided in October 2026."The details ...

Planet Earth is spinning a little faster today — resulting in one of the shortest days of the year. But the change will be so minuscule you won't even notice. We're talking even less time than the ...

Lisa Maynard-Atem, 47, can barely remember what she had for breakfast three days ago, let alone what happened last year. Halfway into 2025, we’ve had World War Three scares, deadly weather events, a ...

Dead satellites and drift-prone GPS coordinates aren't your phone's fault — they're side effects of something unprecedented happening to our planet. Climate change is slowing Earth's rotation at the ...

Tiny changes in Earth’s rotation may reveal a tug-of-war between its deformable inner core, liquid outer core and deep mantle ...

Meltwater from the polar ice caps, combined with the shifting spin of Earth's core, is messing with the Earth's rotation to the point that we might need to adjust for a "negative leap second." The ...

Earth takes 24 hours to complete a full rotation in a standard day, equal to exactly 86,400 seconds. July 9 was the first of three days in which a millisecond or more could be shaved off the clock on ...

On those three days, just over a millisecond is expected to be shaved off the standard 24-hour day. Of course, you're unlikely to notice such a miniscule difference in your day. But scientists who ...

Climate change may be making it harder to know exactly what time it is. The rapid melting of the ice sheets atop Greenland and Antarctica, as measured by satellite-based gravitational measurements, is ...

Grew up back East, got sick of the cold and headed West. Since I was small I have been pushing buttons – both electronic and human. With an insatiable need for tech I thought “why not start a website ...
