In case you’re curious, this is atmospheric airglow, NOT the aurora.

It’s caused by similar, beautiful excitation of atoms like oxygen and nitrogen way up in the atmosphere, but the energy comes from different places. Whereas auroras are caused by the electrons and protons ejected from the Sun in the solar wind, airglow comes from less-intense energized radiation from sunlight itself, like UV rays.
