A 6-second artistic video. 0-2 seconds: the astronaut's wrist lifts slightly as an airbrush sprays fine golden particles; 2-4 seconds: the particles aggregate in the dark universe into a pink-to-orange gradient spiral galaxy (ink wash textures rotate with the galaxy); 4-6 seconds: the camera slowly pushes from the astronaut's silhouette to a close-up of the galactic center, mineral pigment and gold leaf particles float at the edges of the galaxy, matte granular canvas texture is visible throughout, 4K/60fps, cosmic background with faint blue nebula shadows, transparent ink watermarks interweave with heavy mineral pigment color blocks, creating an artistic interstellar creative atmosphere.
