Rogue Planet Awakening

the prompt

Explorers approach a dark rogue planet drifting through interstellar space. Their tiny exploration ship passes over a seemingly dead metallic surface covered in enormous geometric structures. Suddenly kilometers of the planet begin moving. Gigantic plates separate, revealing glowing machinery deep beneath the crust. Entire mountain-sized structures rotate into position while enormous mechanical towers rise from the surface. The camera retreats rapidly as the explorers realize the entire planet is an ancient artificial machine. A gigantic circular eye opens on the planetary surface and emits a beam into deep space. Epic mysterious space opera, cosmic horror undertones, gigantic mechanical scale, photorealistic materials, slow build followed by massive reveal, cinematic lighting and dramatic camera motion.
