      According to the laws of relativity! The details depend on your scenario.

      Well, we don’t know how to make a space ship travel anywhere near as fast as the speed of light. So if you were on a space ship traveling between the planets in our Solar System, for instance, the stars would appear to move pretty much the same way they do from the Earth.

      Even if you were travelling really really Reeeealllllyy fast, because the stars are so so so far apart they would still seem static to the human observer on board the spaceship.

      The stars would however change colour. The ones behind you would get more red and the ones in front of you would look bluer. You would see stars that you wouldn’t normally see, like stars that only emit xrays would look like blue stars if they are behind you for example.

      Unfortunately it wouldn’t look like it does in star trek or star wars.
