Abstract : Photon Dominated Regions or Photo Dissociation Regions (PDRs) have emerged as a class of astrophysical objects by virtue of their ubiquity and prominent presence in the infrared sky. These are one of the most magnificent manifestations of the impact of the radiation from massive stars on the surrounding interstellar medium. The PDRs play an important role in structure formation by cooling the gas and also have been identified to trace a significant amount of molecular gas otherwise not traced by CO. Availability of sensitive and high-resolution spectrometers in the far-infrared during the last decade has vastly improved our understanding of the physical structure and kinematics of gas affected by the radiation from massive stars in our Galaxy. In this talk I will present an overview of the results of our recent observations of a few Galactic PDRs with the Stratospheric Observatory for Far Infrared Astronomy (SOFIA).
