Plasma - the "forth state of aggregation"
The (visible) matter in space is primarily in the plasma state. Plasma phenomena on Earth are found in both flash and nordic light. A plasma is an ionized gas; an ion is an electrically charged atom. As for the solar plasma, the one electron that belongs to the hydrogen kernel (a proton) is 'stripped'. Such a fully ionized plasma, where the atoms have lost all their electrons, is a precondition for nuclear fusion.
