A gothic arch in a vintage illustration reveals the vast universe

In a deep blue retro-styled illustration, a Gothic stone arch stands against a pitch-black background, with the arch frame intricately carved with classical column details. Through the arch, the vast cosmos unfolds before the eyes: a bright spiral galaxy spins in the center, its core glowing white-hot, stars twinkling, and several meteors streaking across the night sky. Below, the horizon of a desolate planet and the contours of circular mountains are faintly visible. The overall composition employs a monochrome blue-black contrast, filled with printing noise, creating a mysterious and tranquil surreal space illusion, as if peering into an alien sky through an ancient oracle's window.
