TL;DR: The Photodetector Array Camera and Spectrometer (PACS) as discussed by the authors is one of the three science instruments on ESA's far infrared and sub-mil- limetre observatory.

TL;DR: Water In Star-forming regions with Herschel (WISH) as discussed by the authors is a key program on the Herschel Space Observatory designed to probe the physical and chemical structures of young stellar objects using water and related molecules and to follow the water abundance from collapsing clouds to planet-forming disks.

TL;DR: In this paper, a diurnally averaged model that couples hydrocarbon and oxygen photochemistry, molecular and eddy diffusion, radiative transfer, and condensation was developed to investigate the details of hydrocarbon photochemistry on Saturn, and the model results are compared with observations from the Infrared Space Observatory (ISO) to place tighter constraints on molecular abundances, to better define Saturn's eddy coefficient profile, and to identify important chemical schemes that control the abundances of the observable hydrocarbons in Saturn's upper atmosphere.

TL;DR: In this paper, the authors analyzed Titan observations performed by the Infrared Space Observatory (ISO) in the range 7-30 μm and obtained the monodeuterated methane-averaged abundance and retrieved a D/H isotopic ratio of 8.7−1.

TL;DR: In this article, the authors show that galaxies with high L{sub FIR/M{sub H{sub 2} ratios tend to have weaker fine structure lines relative to their far-infrared continuum.
