Plasma is typically an electrically quasineutral medium of unbound positive and negative particles (i.e., the overall charge of a plasma is roughly zero). Although these particles are unbound, …

At extremely high temperatures, plasma particles don’t just collide; they fuse, releasing massive amounts of energy. We create plasmas in labs, and we also use theoretical physics to model …

Nov 22, 2025 · Plasma, in physics, an electrically conducting medium in which there are roughly equal numbers of positively and negatively charged particles, produced when the atoms in a …

Plasma is a state of matter along with solids, liquids and gases. When a neutral gas is heated such that some of the electrons are freed from the atoms or molecules, it changes state and …

Studying plasma helps scientists understand matter. It also helps them progress toward the goal of fusion energy. The Department of Energy (DOE) Office of Science supports research into …

Dec 19, 2025 · Plasma physics is the study of a state of matter comprising charged particles. Plasmas are usually created by heating a gas until the electrons become detached from their …

May 22, 2024 · Plasma, making up 99% of the visible universe, exists predominantly in stars and space. It forms when electrons detach from atoms, creating ions and free electrons, a state …

Plasma is superheated matter – so hot that the electrons are ripped away from the atoms forming an ionized gas. It comprises over 99% of the visible universe. In the night sky, plasma glows in …

Plasma science enables prediction of space weather events that can affect the electric power grid, onboard computers, and other instruments on spacecraft, GPS, and communication satellites, …

Plasmas are the most common form of matter, comprising more than 99% of the visible universe, and permeate the solar system, interstellar and intergalactic environments.
