DOE Explains...Plasma | Department of Energy
In laboratory experiments, scientists can blast the atoms with high-voltage electricity, lasers, or electromagnetic fields to form plasma. In space, plasma may form from high-energy photons including gamma rays striking atoms. Plasma can also form in space when gravity increases pressure so much that the pressure super heats gases.
