How come we cannot see stars in space?
Firstly, seeing and photographing are two very different problems. Leaving that aside, however, stars are simply too dim to show up when the camera is correctly set to expose the film for a sunlit object like the shuttle or astronaut or lunar surface. You either get a correctly exposed object with no stars in the background, or stars but a hopelessly overexposed and washed out object. That’s a physical limitation of the image gathering technique, be it film or CCD, and there is no way round it. When you see shots in movies of people under a starry sky, the stars have been added in later. You can photograph stars, but only if you exclude any sunlit object from the frame.
