Abstract:

The humble interstellar dust grain is only a micron sized solid in the vastness of space. But this component of our galaxy has yielded information far out of proportion to its size. An exasperating hinderance to those who study stars, dust is in fact one of the main mechanisms through which the process of star formation is investigated. I will discuss the importance of dust in the particular study of the role of magnetic fields in star formation, which attempt to explain why the process is so grossly inefficient. I will present data from various submillimetre and millimetre telescopes, including a glimpse at the first interferometric detection of polarized emission from an external galaxy made just one week ago.
