What process generates the light (photons) emitted by atoms in nebulae?

Answer

Electron dropping from an excited state to a lower energy level

Light, carried by photons, is generated when an electron within an atom gains energy, jumps to a higher state, and then drops back down to its original, lower energy level, releasing that excess energy as a photon.
