Ten things you may not know about the plasma:
- It’s the fourth state of matter: Solid, liquid, gas, and plasma. Plasma is a super-heated gas, so hot that its electrons get out of the atom’s orbit and roam free. A gas thus becomes a plasma when extreme heat causes its atoms to shed their electrons.
- It’s everywhere. Plasma is the most abundant form of visible matter in the universe – it is thought to make up 99 percent of what we see in the night sky. Plasma populates and dominates the vast regions of interstellar and interplanetary space.
- Stars, like the sun, are gigantic balls of plasma. And there are billions of them, so studying plasma can help us understand the cosmos.
