The answer is: the radiant sun.
There are five fundamental states of matter (gas, liquid, solid, plasma and Bose–Einstein condensate).
Plasma is a an ionised gas with highly electrical conductivity.
It is an electrically neutral with positive and negative particles.
Plasma may be the most abundant form of matter in the universe.
Plasma was first described by chemist Irving Langmuir.
Plasma can be artificially made by heating a neutral gas to a strong electromagnetic field.
