宇宙星雲の空の下に佇む廃墟の断崖天文台

An abandoned observatory perched on a cliff edge, its domed roof partially collapsed, revealing a telescope pointed towards a sky ablaze with cosmic dust and nebulae. The surrounding landscape is rugged and ancient, with hints of forgotten civilizations. The image is rendered with extreme detail, emphasizing the textures of weathered stone and cosmic phenomena, in a photorealistic style with a mystical undertone.
