It is a gas in particular physical conditions, whose atoms have been broken in their respective nuclei (positive ions) and electrons (negative ions). Plasma is therefore a good conductor of electricity and is quite sensitive to magnetic fields.

Most of the gas in space is in a plasma state: at these conditions it is carried well by the high temperatures that are recorded in the proximity of the stars (as the temperature of a gas increases, the atoms collide against each other and are subject to breakage in their fundamental constituents), either by the effect of high-energy radiation, such as ultraviolet rays.

For example, solar wind is a plasma.
