Colossal Alien Spaceship Over a Ringed Planet

Create a breathtaking science fiction scene of a colossal alien spaceship in orbit around a Saturn-like planet. The spacecraft should have a mysterious, non-human design with intricate geometric structures, glowing energy conduits, and an immense scale that dwarfs conventional spacecraft. Below, the planet features swirling clouds, a thin, luminous atmosphere along its curved horizon, and a thin ring. The scene is viewed from space, with countless stars, colorful nebulae, and a distant sun casting dramatic light across the ship's metallic surfaces. The planet's limb glows with soft blues and golds, while the alien vessel is illuminated by eerie cyan and violet energy. The overall mood should evoke awe, mystery, and the feeling of encountering an advanced extraterrestrial civilization. Render the image in a highly detailed, cinematic, photorealistic style with stunning lighting, sharp textures, and an epic sense of scale.
