It was an ionized gas, which was generated by heat or by subjecting a neutral gas to a strong electromagnetic field to the point where it was electrically conductive. The sun, among other stars in the universe, was composed mainly of plasma. References ↑ As seen in The Adventures of Superboy episode King Superboy (1968).
