A celestial woman embodying the night sky stands gracefully on a marble observatory balcony high above the clouds, draped in flowing midnight-blue silk robes embroidered with glowing zodiac constellations in gold thread. She holds a delicate armillary sphere that emits soft cosmic light, while translucent astral ribbons spiral gently around her body. A radiant halo of starlight floats behind her head, and her calm, timeless expression reflects galaxies in her eyes. The deep indigo sky is filled with stars and nebulae, rendered in a painterly fantasy style with intricate ornamentation, luminous highlights, and elegant Art Nouveau linework.
