The shorter the wavelength, the higher the extinction -- blue light is affected more strongly than red light. Therefore, stars behind a lot of dust look redder … richmond roller coaster

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. … 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. 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. richmond rolling solutions epping
