Interstellar dust cloud

WebAbstract This review surveys the observed properties of interstellar dust grains: the wavelength-dependent extinction of starlight, including absorption features, from UV to infrared; optical luminescence; infrared emission; microwave emission; optical, UV, and X-ray scattering by dust; and polarization of starlight and of infrared emission. The … WebEffects of Interstellar Material on Starlight. The components of the interstellar medium — atoms, molecules, and dust grains — directly affect the light emitted by stars. When light from a distant star passes through the material between stars, the interaction changes the light's properties, such as its intensity in different colors.
