The great challenge facing current measurements of the cosmic microwave background is to account for the various background emissions from our galaxy. From the cosmological viewpoint, this is a nuisance, but it can often be interest in its own right. A case in point is the galactic dust emission that depends on variations in grain properties and radiation field throughout the galaxy and whose characteristics are needed for interpreting of data from Planck and other missions. The paper by Compiegne et al. highlighted in this issue illustrates a simple numerical tool developed for this purpose and it illustrates some applications.
