Phi hành gia giữa ngân hà

A cute cartoon-style astronaut floating in outer space, centered in the composition, wearing a clean white spacesuit with blue accents and a glossy black reflective helmet visor. The astronaut has a soft, rounded, chibi-like design with simplified details, giving a friendly and playful appearance. Arms are slightly spread outward as if drifting in zero gravity, with a relaxed floating pose.

Surrounding the astronaut are multiple colorful planets of varying sizes scattered across the scene. Some planets have rings similar to Saturn, while others are smooth or softly textured. The planets are rendered in pastel tones such as teal, blue, purple, orange, and pink, with subtle gradients and soft shading.

The background is a vibrant cosmic nebula with a smooth gradient blend of deep blue, purple, pink, and cyan colors, creating a dreamy galaxy atmosphere. Small glowing stars, sparkles, and light dots are evenly distributed throughout the space, along with thin constellation-like lines connecting some stars, adding a whimsical and magical feel.

Lighting is soft and evenly diffused, with gentle glow effects around stars and planets. The overall style is flat illustration combined with soft gradient shading, clean vector-like outlines, and high color saturation. The image has a polished digital art look, suitable for wallpapers or children-friendly space themes.
