Is it possible to recreate Aurora's in a laboratory experiment? Obviously, I'm not asking if it's possible to have bands of plasma thousands of kilometers long inside a lab. But rather, is it possible to create a particle stream analogous to solar winds, and ionize low-pressure gas into a plasma using this artificial solar wind? If it is possible, has this been done before?
Certainly. Classroom demonstration tubes can be bought that create colored ionization patterns inside when connected to a high voltage DC source. By putting different gases into the vacuum in tiny amounts, you get different colors. these are called glow discharge tubes. I watched while my science teacher demonstrated these to us in 1965.
