Could life as we know if survive if our solar system were to pass through a nebula?

If it could:

Would we be able to have much of an understanding of the physical universe if we were inside a nebula, or would our view be too distorted?

Nebula aren't like you see in sci-fi -- the gas density is really low. I doubt anything would happen if we passed through one.

If I were to come up with a rough analogy, could I equate it to not being able to see our atmosphere, compared to the glow of the atmosphere that we see from space.

Of course we need to ignore some analogy shortcomings, like the fact that we do actually see the atmosphere because we see the blue, but I'm thinking of how we see objects in the atmosphere.
