Hail folks.

I've been reading a lot about generation ships lately and this occurred to me: imagine a ship that tries to emulate perfectly life on earth (atmosphere and all).

Leaving aside the matter of how they emulate the sun, let's say the night sky view is just plain space through where the ship flies.

Does that mean the sky will be different at each nightfall (misplaced stars and stuff) since the ship is moving?

I would appreciate if you guys could elaborate detailed on this.

Sorry for my poor english; I'm not fluent.

Thanks.
