How bright would the sun look if the solar system was inside one of those dark interstellar dust clouds?
Question:
Answer:
Those clouds are actually quite thin, so 93 million miles of dust probably wouldn't dim things much. Plus the solar wind should clear a good-sized bubble. I'd guess the most noticeable difference would be that the night sky would have a dim glow (from reflected sunlight), and no stars.
Well, it certainly would not look as bright as it does today because some of the light would be diffused by the dust particles. Over time those dust particles and gas would be burned up/off by the radiation from the Sun, however. Time is relative here, since we are talking about things that take thousands and millions of years to happen.
let me see how bright the sun look tomorrow first.
How dense is the dust cloud...?
From how far is the sun being observed...?
You probably would not notice the difference. The nebulae, while spectacular, are still an almost perfect vacuum. The dust particles are quite far apart. It would not block enough light at such as small distance as 200 million Km to be noticeable.
