Astronomers have long known pre cisely how fast the earth moves as it cir cles around its own star, the sun (66,500 m.p.h.), and how fast the solar system revolves around the core of its own galaxy, ...

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 ...

We examine why the Earth's constant spin goes completely unnoticed by the people living on it. We think about it and then ...

Your motion through the universe is extremely complicated, so let’s figure it out! Perhaps you’ve seen videos of how the planets of the solar system move through the universe in this cool helix. Not ...
