Why is the sun made of plasma?

Plasma is an ionized gas that has an electric current present in it and the temperature is a product of that current flow and particle density. Thermal radiation can be added to a plasma to increase the speed at which the particles in the plasma move, but that has the effect of increasing the current flow. read more

The Sun is composed of plasma, fire is plasma, fluorescent and neon lights contain plasma. "99.9 percent of the Universe is made up of plasma," says Dr. Dennis Gallagher, a plasma physicist at NASA's Marshall Space Flight Center. read more

A Star and hence our Sun, is an almost entirely ionized ball of plasma, consisting of electrons and ions, in which there is hardly any gas (neutral atoms). The movement of the plasma produces strong magnetic fields and corresponding electric currents. read more

It is not just the sun, 99.999% of detectable matter in the universe is made of plasma. That means every galaxy, every star, every nebula, every galactic jet, many formations that we cannot see with the naked eye are all made of plasma. read more

The light passes through the outer layers of the sun's atmosphere — the chromosphere and the corona. We usually can't see these layers, but during a total solar eclipse, the chromosphere looks like a red rim around the sun, and the corona forms a white crown with plasma streamers spreading outward. read more
