Having spent my previous career studying the effects of interstellar dust (though not in this wavelength range), it's amazing how often I would be the buzz kill by arguing that something that someone saw actually probably could be explained by dust. It has major effects on the radiation we receive and its effects are sensitive to the exact details of how it's distributed and what it's composed of.
