I was having a look at the APOD today of the reflection nebula in Orion (
http://antwrp.gsfc.nasa.gov/apod/ap061010.html) and had an interesting thought.
While reflection and emmission nebula are magnificent to look at from parsecs away, what would we see if our solar system were in the middle of it? Would the night sky be dominated by light haze or is it so diffuse that we'd see nothing at all?
