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. WebDust reddens and dims starlight passing through it, as in our atmosphere at sunrise and sunset. La polvere rende rossa e debole la luce stellare che vi passa attraverso, come avviene nella nostra atmosfera all'alba ed al tramonto. The first clue to the origin of starlight happened as recently as 1899: radioactivity.

WebMar 1, 2008 · Dust reddens starlight same as it reddens our sunsets and sunrises. This will make estimating the loss to dust and gas rather difficult. I'm sure all sorts of methods of adjusting for this will be tested by this event. M82 is also Arp 337 so I've added another supernova to my collection of Arp galaxies.

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.
