A majestic interstellar library floating in the sky above a lush, Earth-like planet. The library is a massive, radiant structure inspired by the ancient Library of Alexandria, reimagined with futuristic materials — translucent domes, golden inscriptions, hovering platforms, and intricate light patterns. Small spacecraft glide gracefully in and out of the structure, like knowledge-seeking pilgrims, docking at luminous gateways. In the distance below, a harmonious futuristic city is nestled in green landscapes, blending seamlessly with rivers, trees, and gentle hills. The atmosphere is ethereal, with soft clouds surrounding the floating library like a protective veil. The entire scene conveys reverence — a sacred temple of knowledge suspended between earth and stars.
