Have you ever wondered why all the planets in our solar system orbit in the same plane? This fascinating characteristic of planetary orbits has intrigued astronomers for centuries. When we observe the ...

Thanks to atomic clocks (and all the worldly forces that influence them), scientists know that Earth's rotation has begun to ...

How is it possible for the ISS to stay in orbit? Learn more about the science behind orbiting Earth and more in this NASA "STEMonstrations" video. Credit: NASA Johnson Space Center Markets plummet ...

To see this, recall the definition of angular momentum: From this relation and the animation below, we see that when the satellite is at its closest position to the Earth (the position of minimum R is ...

In our solar system, the giant gas planets (Jupiter, Saturn, Uranus, and Neptune) spin more rapidly on their axes than the inner planets do and possess most of the system's angular momentum.

Together with the earlier results, this indicates that three properties of electrons—spin, charge, and orbital angular momentum—can in principle be separated into three quasiparticles.
