Why you should care about dust!

Joerg Fischera,   ANU

Although only a small fraction of the total mass (less than 1%) of the interstellar medium is condensed in grains, dust will play a tremendous role in various modern astrophysical disciplines for the next decade. Several important effects arise from the ability of interstellar dust to attenuate light through dust absorption and scattering and to reprocess the absorbed emission to infrared radiation. In the talk I will highlight some essential problems for observational astrophysics and will discuss possible solutions based on our current understanding of the physical properties of interstellar grains.
