Plasma – EMC
Plasma is the 4th state of material.
It is found at different temperatures and pressures but above all plasma is electrically charged, commonly referred to as ionized. The surface of our star, the sun, is made up of this molten material and when solar flares occur, the plasma forms circles circumscribed by the different forces exerted by the mass of the sun. These eruptions are called Coronal Mass Ejections: CME.
