What's the likelihood of light striking some interstellar gas and being absorbed, then re-emitted, and the re-emitted light actually being the light we see rather than the original light from the source? Also, what about the likelihood of reemission after passing through the heliosphere? Anyone care to make a rough guess at the percentage of light that reaches us that is not filtered this way? Are there any particular wavelengths of light that might be more likely to make it through because they aren't likely to be absorbed by the interstellar medium or the heliosphere?
