WebThe fact that starlight is reddened by interstellar dust means that long-wavelength radiation is transmitted through the Galaxy more efficiently than short-wavelength radiation. … WebInterstellar reddening is caused by the preferential absorption of blue light over red light. Image source Interstellar medium is the material between the stars, made up of dust and gas. In places the matter is very thin and tenuous, other places the dust is very thick and can obscure the light from faraway stars. Image source

"WebInterstellar dust can be detected: (1) when it blocks the light of stars behind it, (2) when it scatters the light from nearby stars, and (3) because it makes distant stars look both redder and fainter. These effects are called reddening and interstellar extinction, respectively. " - Dust reddens starlight because

The light can be totally blocked if the dust is thick enough or it can be partially scattered by an amount that depends on the color of the light and the thickness of the dust cloud. All wavelengths of light passing through a dust cloud will be dimmed somewhat.
