Phi Hành Gia Nhí Vũ Trụ

A cute, colorful cartoon illustration of outer space designed for children, featuring two happy kids dressed as astronauts standing on a large yellow ringed planet (similar to Saturn). The kids have big round eyes, cheerful smiles, rosy cheeks, and are wearing white astronaut suits with helmets and control panels on their chest. Their poses are playful and energetic, with arms raised as if floating in zero gravity.

The central planet is bright yellow-orange with circular crater patterns and a large ring wrapping around it horizontally. The background is a deep dark blue starry sky filled with many colorful elements: multiple planets of different sizes and colors (green, blue, purple, orange), some with rings, some with craters.

Include several cartoon-style rockets flying around with bright orange flames, a small comet with a glowing tail, and tiny stars scattered everywhere in yellow and white. Add soft purple clouds floating in space for a dreamy, whimsical effect.

Style: kawaii, children's book illustration, vibrant colors, smooth shading, clean outlines, highly detailed, playful and imaginative.
Lighting: bright and even, high saturation.
Composition: centered main subject (two astronauts on the ringed planet), surrounded symmetrically by space elements.
Resolution: high detail, 4K, sharp focus.
