A hyper-realistic cinematic sci-fi suspense scene at a remote mountain observatory beneath a crystal

A hyper-realistic cinematic sci-fi suspense scene at a remote mountain observatory beneath a crystal-clear star-filled night sky. A lone astronomer stands beside a massive telescope when they notice a strange patch of complete darkness among the stars. They look upward as stars begin vanishing rapidly in sequence, a gigantic wave of blackness sweeping silently across the sky. Within seconds, nearly half the heavens disappear. The astronomer steps backward in disbelief as moonlight briefly catches something overhead-the darkness is not empty space but the underside of an impossibly enormous object silently passing above Earth. As it moves closer, faint reflections reveal colossal metallic structures, kilometer-wide trenches, mechanical towers, and glowing geometric lines stretching beyond the horizon in every direction. The object now covers almost the entire sky, making the observatory appear microscopic beneath it. Then thousands of enormous circular lights ignite sequentially across its underside, revealing its terrifying scale. For the final payoff, the camera pulls high above the atmosphere and reveals that the structure passing over Earth is a planet-sized spacecraft, its shadow swallowing an entire hemisphere as it slowly turns toward the planet.
