Dust reddens starlight because
WebStarlight passing through a dust cloud can be affected in a couple of ways. 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. http://burro.astr.cwru.edu/Academics/Astr221/StarProp/dust.html

Did you know?
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 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.
WebIt is likely that the polarization arises because the dust grains are partially aligned by the galactic magnetic field. If the dust grains are paramagnetic so that they act somewhat like a magnet, then the general magnetic field, … WebDec 20, 2015 · It is similar with interstellar dust, only the dust particles are much smaller than typical terrestrial smoke particles so the color effects are greater. Those small …
WebStarlight will reflect on the grains of dust in the nebula, giving it the name Reflection Nebula. Another type is a Dark Nebula. These are very dense clouds ... Life Cycle Of Stars Research Paper If there are dense enough clumps in this nebula, … Webstarlight passed through. Dust and air in the atmosphere also dims and reddens starlight... The longer the path length the starlight traverses through the atmosphere, the more it is dimmed. Thus, a star close to the horizon will be dimmed more than one close to the zenith. The path length through the atmosphere is known as the air mass.
WebDust reddens starlight because it a. re-emits the light it absorbs at red wavelengths. b. emits mostly in the infrared due to its cold temperature. c. is made mostly of hydrogen, …
