Stellar feedback processes from massive stars create pillars, globules and other features at the interface between the HII region and molecular cloud and external UV-radiation produces photodissociation regions (PDRs) on their surfaces. A rare example of a globule suggested to be also illuminated internally by massive stars is IRAS20319+3958 in Cygnus X. We will start with a morphological classification scheme based on Herschel imaging observations of UV-illuminated features in Cygnus X and then focus on the globule IRAS 20319+3958, that was observed in a large set of far-infrared lines (mid-to high-J CO lines with Herschel/PACS and SPIRE, the [CII] 158 micron line with Herschel/HIFI and SOFIA, and the [OI] 63 micron line and the 12CO 16-15 line with SOFIA). The spectroscopic data reveal that the globule is rotating and that it contains a highly collimated C+ outlow, possibly driven by a Herbig Be star. Employing the KOSMA-tau PDR code, we are able to model most of the emission lines with a clumpy and a non-clumpy component for the head and the tail of the globule, respectively.
