Rosette nebula as seen by GALEX in the NUV band (Rosette was not mapped in the FUV band). The image is a compositeof 13 NUV images assembled using the MOSAIX tool (Armengot et al. 2014). Top panel: high contrast image. Bottom panel: same image in logarithmic scale to enhance the structures at low signal level. Coordinates are ICRS: right ascension increases from right to left (in degrees) and declination from bottom to top.
