Celestial Night Sky Enchantress

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