One of the major factors influencing both the morphology and evolution of spiral galaxies is the abundance and distribution of dense interstellar matter. Young stars formed from the gas clouds are responsible for the appearance and perhaps even the maintenance of the spiral pattern. Since these stars also generate a disproportionate share of the galactic luminosity, the long term evolution of galaxies is directly related to the exhaustion of this matter (i.e., its absorption into low mass stars). The ability to probe all three gas components (molecular, atomic, and ionic) in addition to the luminosity from the young stars is a unique capability of the far infrared.
