Question:
Is there a part in space where you cannot see a star with the human eye?



Replies:
I can think of two situations for not being able to see any stars with the naked eye. One is: you are too far away from any stars to see any. There are surely vast regions of the universe, in intergalactic space, where no stars may be seen. (Every star we see at night is in our own galaxy; I have read that the Andromeda galaxy, the nearest galaxy to ours, may be seen as a faint, fuzzy patch of light in the night sky [I have never seen it myself], but no individual stars from that galaxy may be seen. Thus, it seems reasonable to me that one could be far enough away from all of the "local" galaxies that none of their stars could be seen.) The second situation: something in your environment obscures all starlight. This would certainly be the case if you were on the surface of a planet with permanent thick clouds, like Venus or Jupiter, or merely with a deep, hazy atmosphere like Uranus or Neptune. And I suspect that there are dust clouds in our galaxy that do not allow starlight to penetrate completely into their interiors.
