The colors of autumn appear in this cloudy nebula in which a few proto-planets have already formed. These nebulas look like steamy vapor to us but in reality they are made of a thin cloud of inorganic and some organic (containing carbon and oxygen) molecules. It may look thick and opaque but if you were in it I don't think you would have much cosmic smog, it is actually quite tenuous and rarefied compared to the atmosphere here on Earth. As always, the colors are artificially enhanced, both in photographs and in artist's conceptions.
