Planet Earth will spin a little faster on three separate days this summer, starting today. This will technically result in shorter days, but the change will be so minuscule you won’t even notice.

Take a look out there at the Universe, and while the stars might give off the light that you'll first notice, a deeper look shows that there's much more out there. The brightest, most massive stars, ...

A fresh study by Avi Loeb suggests that the interstellar visitor 3I/ATLAS may be losing its rotational speed, sparking ...

New research has revealed the importance of a circadian body clock that matches the rotational speed of the Earth. New research has revealed the importance of a circadian body clock that matches the ...

DETROIT — The days are indeed getting shorter. Earth had its shortest day ever recorded on June 29, with the day ending 1.59 milliseconds sooner than usual, according to the National Physical ...

Researchers have clarified the mechanisms by which energy loss is locally maximized at a certain rotational speed in ...
