The air is crystal clear, with no light pollution, allowing the stars to shine brightly above. A gentle aurora borealis paints the sky in soft hues of green, blue, and purple, adding an ethereal touch to the landscape. In the background, futuristic buildings glow softly with ambient light, while lush greenery and forests surround the city. The night feels peaceful and tranquil, a harmonious balance between the natural world and the quiet brilliance of modern architecture. The scene exudes a sense of wonder, with the vastness of the universe contrasting beautifully with the serenity of the earth below.
