Earth spun just a bit faster than usual on July 9 and is expected to do so again on July 22 and Aug. 5, according to the website TimeAndDate. Over a millisecond was reportedly shaved off the clock on ...

Researchers led by Mitchell and Kirscher found Earth’s rotation paused for nearly a billion years, challenging models of steadily lengthening days caused by lunar tidal braking and showing the ...

While the Earth on June 29 did indeed record its shortest day since the adoption of the atomic clock standard in 1970 — at 1.59 milliseconds less than 24 hours — scientists say this is a normal ...
