broader: Interstellar absorption
broader: Interstellar scattering
definition: The dimming of light traveling in the interstellar space due to the combined effects of absorption and scattering by interstellar dust particles. Interstellar extinction increases at shorter (bluer) wavelengths, resulting in interstellar reddening.
