The ionization of interstellar gas and the heating of dust near the galactic center are usually assumed to be dominated overall by the radiation emanating from young, massive stars. This paper questions that assumption by pointing to the paucity of direct evidence for current star formation and by considering alternative sources of ionization and luminosity. It is suggested that star formation can be inhibited by the strong, poloidal magnetic fields observed in the galactic center. The presence of some red supergiants (e.g., IRS7) can be understood if massive star formation occurs episodically.
