Not content with protons and atomic nuclei, physicists took a new kind of particle for a spin around the world’s most powerful particle accelerator. On July 25, the Large Hadron Collider, located at ...

Learn why aurora colors glow green and red, how ionized particles collide with atmosphere layers, the physics of green aurora ...

(Nanowerk News) Two separate research fields have been united in Hamburg for the very first time. Ultrashort laser pulses enable us to observe and manipulate matter on very short time scales, whereas ...

Nearly 4.5 million years ago, two large, hot stars brushed tantalizingly close to Earth's sun. They left behind a trace in ...

For decades, astronomers have detected an unusual mix of ionised gas in the local clouds. Roughly 20% of hydrogen and 40% of ...

Light interacting with hydrogen atoms enclosed in hollow cages composed of carbon atoms - referred to as fullerene material - produces ionisation. This phenomenon, which has been the subject of ...

In the electronics industry, thin metal films are deposited on silicon wafers with a sputter gun, which uses energetic ions - atoms with a positive charge - to knock the metal atoms off a target.

Why can't neodymium be more like tin? Well it can, if you ionize it enough. Why strip atoms of a dozen or more electrons? To make them more amenable for use in atomic clocks and quantum computers. The ...

Rydberg atoms, atoms whose outermost electrons are highly excited but not ionized, might be just the thing for processing quantum information. These outsized atoms can be sustained for a long time in ...

Neutral atoms were formed just a few hundred thousand years after the Big Bang. The very first stars began ionizing those atoms once again, but it took hundreds of millions of years of forming stars ...
