A dramatic shift in Earth’s magnetic field occurred roughly 41,000 years ago during what scientists now call the Laschamps ...

A new model uncovers how Earth’s liquid core has sustained its magnetic field since the planet’s beginnings, offering new ...

Would you guess that the Earth is spinning at 1,000 mph around its axis and at the same time hurtling through space on its ...

The study of polar motion and Earth's rotation dynamics encompasses the investigation of subtle shifts in the orientation of the planet's rotation axis relative to its crust. These motions are ...

Earth rotation and polar motion prediction encompass the estimation and forecasting of key parameters that describe the rotational behaviour of our planet. These predictions are pivotal for ...

A typical desk globe is designed to be a geometric sphere and to rotate smoothly when you spin it. Our actual planet is far less perfect — in both shape and in rotation. Earth is not a perfect sphere.

Scientists believe that the motion of Earth's continents through plate tectonics has been largely steady over millions of years. New research, however, suggests this drift can speed up or slow down ...

So the bottom line is that the gravity of the closer tidal bulge on the Earth is pulling the Moon forward, which increases ...

PASADENA, Calif. — Humans have yet to see Earth’s center, as did the characters in Jules Verne’s science fiction classic, “Journey to the Center of the Earth.” But a new NASA study proposes a novel ...
