"Among the . . . particles responsible for the scattering (the reflected star light illuminating these structures) are carbon compounds (e. g. diamond dust) and compounds of other elements such as iron and nickel. The latter two are often aligned with the galactic magnetic field and cause the scattered light to be slightly polarized."
