Pair A and B

A celestial diagram illustrates the orbital paths of the stars Castor and Pollux, with a smaller orbit for the binary system of Castor B and Castor C, all set against a starfield with a grid overlay. The scene then cuts to a low-angle view of a tall, cylindrical industrial smokestack against a cloudy sky, where several large, flat, circular objects with faces painted on them are seen rotating around the structure.
