Astronaut Overlooking Alien City From Crystalline Mountains

A lone astronaut stands on the edge of a colossal, crystalline mountain range that pierces the atmosphere of an alien planet. Below, a city of impossible geometry glows with soft, pulsating lights. The sky is a canvas of swirling auroras in hues of emerald and amethyst. This is a high-resolution, photorealistic render with a touch of cosmic horror and a profound sense of scale, inspired by the works of H.R. Giger and Zdzisław Beksiński.
