      Actually, both lightning and the Sun are partly made from plasma!

      Plasma is what you get if you tear atoms apart and separate the negatively charged electrons from the positively charged protons in their cores. This is what happens in lightning, at a temperature of around 30,000C!

      It’s also what happens on the outer atmosphere of the Sun, known as the corona, but there the plasma is much, much hotter, at around 1,000,000C. That’s even hotter than it would be if you were standing on the surface of the Sun! No one knows why this plasma in the Sun’s atmosphere is so hot. It’s called the ‘coronal heating problem’, and lots of scientists are still working on it.
