The Photoconductor Array Camera and Spectrometer (PACS) contains a camera and low to medium resolution spectrometer for wavelengths in the range 55-210 μm. The opening of this infrared window by PACS to sensitive photometry and spectroscopy at high spatial resolution will address a wide range of key questions of current astrophysics concerning the origins of stars, planetary systems, galaxies, and the evolution of the Universe.
