Titan, the largest moon of Saturn, is truly a remarkable world. It has a thick atmosphere as well as rivers, lakes, and seas ...

In its earliest days, Jupiter may have been even more colossal than it is now—twice as large, in fact, with a magnetic field ...

The orbital angular momentum of electrons has long been considered a minor physical phenomenon, suppressed in most crystals ...

The new calculations, described in a paper published Tuesday (May 20) in the journal Nature Astronomy, suggest that just 3.8 ...

"This gives us a direct look at a material's electronic structure in momentum space," explains Ünzelmann. "By cleverly ...

To better understand Jupiter’s primordial stages, researchers turned to the tiniest of the planet’s 92 known moons. Almathea ...

But really, what the heck is angular momentum? Let me start with the following situation. Imagine that there are two balls in space connected by a spring. Why are there two balls in space?

"There isn't anything that doesn't rotate." That's due to angular momentum: When two objects in space move close together, their mutual gravity pulls them toward each other, and if they don't ...

It can also exist for properties that are harder to imagine, such as angular momentum. This property is ... to the photon's rotational motion in space. This is intuitively similar to Earth ...
