Vertical (3:4) Surrealist Poster for a Cosmic Observatory

Design a vertical (3:4) surrealist poster for a cosmic observatory with a 4K resolution, set against an ultra-dark navy backdrop (#0A0A2C). At the center, place a delicate 3D crystalline sphere resembling an ancient astrolabe, accentuated with intricate metallic engravings that emit a faint glow in ultraviolet (#8F00FF) and pale gold (#FFD700). Surround the sphere with a dynamic, ethereal mist composed of swirling nebulae transitioning through shades of soft pink (#FFC0CB) and midnight blue (#191970), creating a celestial and dreamlike ambiance. Use cool directional ambient lighting to enhance the visibility of the carvings while casting fragmented light refractions into the misty surroundings, evoking floating stardust and subtle otherworldly halos. Incorporate typography overlapping the sphere and designed in a style reminiscent of vintage astronomical charts: • The main title, written in elegant serif font and shimmering in pale gold, reads “THE COSMIC ARCHIVE,” centrally aligned and intersected by the glowing edges of the sphere. Behind the sphere, the text appears distorted and refracted, mirroring the crystalline aesthetic. • Below the main title, the subtitle reads: “UNVEILING THE STARS” in slender italicized sans-serif lettering in silvery white (#E0E0E0). The subtitle remains smaller in size, softly glowing as though illuminated by the sphere without distortion. Ensure the composition achieves a balance between intricate detailing and expansive negative space, utilizing cinematic lighting and HDR luminance to maintain sharpness and clarity.
