  We examine Herschel Space Observatory images of one nearby prototypical outer
ring galaxy, NGC 1291, and show that the ring becomes more prominent at
wavelengths longer than 160um. The mass of cool dust in the ring dominates the
total dust mass of the galaxy, accounting for at least 70% of it. The
temperature of the emitting dust in the ring (T=19.5+/-0.3K) is cooler than
that of the inner galaxy (T=25.7+/-0.7K). We discuss several explanations for
the difference in dust temperature, including age and density differences in
the stellar populations of the ring versus the bulge.
