We all know that red-shift or blue-shift indicate whether a light source is moving towards us or away from us, but I hypothesize another 'shift' involving stars with paths perpendicular to earth. If you are driving by person in a car, and you throw a ball directly at them, then you will miss because the car has a velocity of its own. If a star is emitting light, and it is in movement (all known are), then will the light move diagonally and outwards like if you threw a ball from a moving car, or will it radiate directly from its source on its own vector?
