Paintings in the Art Nouveau style, mucha_style. A solitary female astronaut wearing a retro-futuristic spacesuit with sleek, flowing metallic armor plates. Her glass helmet reflects distant nebulas. The circular halo behind her is composed of stylized planetary orbits, stars, and intertwining fiber-optic cables emitting a soft blue glow. The background features a cosmic mosaic in muted blues, silvers, and gold. Strong outlines, highly decorative.
