Google and CFS aren’t alone in their ambitions. Microsoft inked a deal in 2023 to purchase electricity from a nuclear fusion ...

The precursors of heavy elements might arise in the plasma underbellies of swollen stars or in smoldering stellar corpses. They definitely exist in East Lansing, Michigan.

What we saw in the DESI experiments, and now strengthened by our South Pole Telescope observations, is that dark energy is ...

An atom consists of a heavy center, called the nucleus, made of particles called protons and neutrons. An atom has lighter ...

Even when they are in their lowest possible electronic energy level (i.e., the electron's ground state), these two nuclei can still rotate and vibrate, producing a wide range of rovibrational states.

Two German physicists have reimagined how to create powerful and uniform magnetic fields using compact permanent magnets. By ...

Two German physicists have unveiled a compact magnet layout that outperforms the famed Halbach array, delivering stronger, ...

Hydrogen fusion works in the opposite way by forming “paperbag” nuclei out of smaller units. Deuterium (heavy hydrogen), for instance, has one proton and one neutron in its nucleus.

3. The nuclei of hydrogen are positively charged; therefore, they want to repel due to the force of electromagnetism (like charges repel). However, if the nuclei are moving fast enough to collide ...

In laboratories, coaxing hydrogen nuclei to fuse into helium requires creating and confining a “plasma”—an electrically charged gas, where electrons are no longer bound to atomic nuclei—at ...

I love simple questions that wind up having complicated—or at least not straightforward—answers. Astronomers twist themselves into knots, for example, trying to define what a planet is, even ...
