Create Infographic Space Poster for Classroom Steps

Educational infographic poster titled "How to Create a Space Infographic" in portrait layout, designed for students / classroom use, with sharp readable text labels in clean sans-serif English typography. Simple 4-step composition with large numbered badges, short captions, and clear connecting arrows flowing from top to bottom. Theme: astronomy / space, presented as a retro 1950s science poster fused with a tech neon cyan & magenta palette; upbeat, educational, futuristic classroom mood. Use magazine-grade editorial illustration, vector-clean lines, no photographic textures.

1. heading: "Choose Topic"; caption: "Pick one clear space idea to explain." Visual: a glowing poster board with a ringed planet, crescent moon, and small star cluster, plus a magnifying glass hovering over the icons; large number "1" in a circular badge.

2. heading: "Gather Facts"; caption: "Collect 3 key points and one simple metric." Visual: a clipboard with neat data cards showing a rocket, Earth, and telescope icons, a small bar chart, and tiny labeled dots orbiting a planet diagram; large number "2" badge.

3. heading: "Arrange Layout"; caption: "Place title, icons, labels, and arrows in order." Visual: a wireframe infographic panel with boxes for title, captions, and circular diagrams, connected by arrows; include a ruler, grid lines, and a small orbit path guiding the eye; large number "3" badge.

4. heading: "Add Visual Style"; caption: "Use bold colors and clean space symbols." Visual: the final polished poster shown on an easel-like frame, featuring neon cyan and magenta planets, comet trails, stars, and crisp labels, with sparkle accents and a finished checklist icon; large number "4" badge.

Connect all four stages with thick directional arrows and dotted orbit lines, clearly numbered in sequence 1 to 4. Include a small side legend panel with the exact labels "Icon", "Caption", "Arrow", and "Metric" next to tiny sample symbols. Background: dark navy space field with subtle starbursts, atomic-age geometric shapes, concentric circles, and mid-century sci-fi poster framing. Keep the composition uncluttered and easy to read for beginners.

All text MUST be written in English (array). Every heading, label, caption, legend and metric name in the image must be in English — not English. Spell each English word correctly using English characters and diacritics. Numbers stay as digits, no watermarks Render labels and headings in clean English typography (sans-serif). No real-brand logos, no copyrighted characters, no people that could be identified, no graphic medical content. If the topic touches a regulated domain (medicine, finance, law), keep the explanation conceptual and add no specific dosages, prices or legal advice.
