Planetary nebulae are characterized by an emission spectrum consisting of balmer (hydrogen) emission lines and a pair of strong emission lines at 4959˚a and 5007˚a that were quite mysterious when first seen. describe the process that is responsible for the production of these lines. where does the energy that is radiated in these lines come from? why were these lines so mysterious when first observed?
