It is the most abundant form of ordinary matter in the universe, mostly in stars (including the Sun), but also dominating the rarefied intracluster medium and intergalactic medium. [2][3][4][5] Plasma can be artificially generated, for example, by heating a neutral gas or subjecting it to a strong electromagnetic field.
Princeton Plasma Physics Laboratory (PPPL) is a United States Department of Energy national laboratory for plasma physics and nuclear fusion science. Its primary mission is research into and development of fusion as an energy source. It is known for the development of the stellarator and tokamak designs, along with numerous fundamental advances ...
In physics, a state of matter is one of the distinct forms in which matter can exist. Four states of matter are observable in everyday life: solid, liquid, gas, and plasma. Many intermediate states are known to exist, such as liquid crystal, and some states only exist under extreme conditions, such as Bose–Einstein condensates and Fermionic ...
Astrophysical plasma. Lagoon Nebula is a large, low-density cloud of partially ionized gas. [1] Astrophysical plasma is plasma outside of the Solar System. It is studied as part of astrophysics and is commonly observed in space. [2] The accepted view of scientists is that much of the baryonic matter in the universe exists in this state.
A corona (pl.: coronas or coronae) is the outermost layer of a star 's atmosphere. It is a hot but relatively dim region of plasma populated by intermittent coronal structures known as solar prominences or filaments. The Sun 's corona lies above the chromosphere and extends millions of kilometres into outer space.
Eric J. Lerner (born May 31, 1947) is an American popular science writer and independent plasma researcher. [2] He wrote the 1991 book The Big Bang Never Happened, which advocates Hannes Alfvén 's plasma cosmology instead of the Big Bang theory. He is founder, president, and chief scientist of LPP Fusion.

Solar prominence. Solar prominence seen in true color during totality of a solar eclipse. In solar physics, a prominence, sometimes referred to as a filament, [a] is a large plasma and magnetic field structure extending outward from the Sun 's surface, often in a loop shape. Prominences are anchored to the Sun's surface in the much brighter ...
Waves in plasmas. In plasma physics, waves in plasmas are an interconnected set of particles and fields which propagate in a periodically repeating fashion. A plasma is a quasineutral, electrically conductive fluid. In the simplest case, it is composed of electrons and a single species of positive ions, but it may also contain multiple ion ...
