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. WebDust reddens starlight because it it preferentially affects light at optical and shorter wavelengths Dust that is heated to 30K will emit a blackbody spectrum that peaks at 100 …

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.
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.
WebDust reddens starlight because itANS: preferentially affects light at visible and shorter wavelengths. What is the most likely explanation for the dark area in the figure shown?
