Free Health Infographics Style Space Observatory Poster

Educational infographic poster titled "How Space Observatories Read Cosmic Signals"; portrait layout, clean vertical composition, text labels must be sharp, high-contrast, and fully readable in crisp English sans-serif typography. Create a simple 4-step educational sequence for a general public audience, with large numbered labels, short captions, and clear connecting arrows flowing from top to bottom.

1. heading: "1. Capture Light"; caption: "Telescopes collect light and other signals from distant space."; visual: retro 1950s-style observatory telescope dish and tube telescope aimed at a star field, with cyan and magenta beams entering the instruments, small icons for visible light, radio waves, and infrared, plus a curved arrow showing signals traveling inward.

2. heading: "2. Focus The Signal"; caption: "Mirrors, lenses, or dishes concentrate the incoming energy."; visual: cutaway diagram of a telescope interior showing a parabolic dish and reflective mirror funneling glowing cyan-magenta rays toward a focal point, with dotted guide lines and a small labeled focal target symbol.

3. heading: "3. Convert To Data"; caption: "Detectors turn cosmic energy into measurements scientists can study."; visual: simplified sensor panel and readout module converting incoming rays into clean graph lines, waveform icons, and pixel-grid data squares, with arrows from detector to data display and small meter-like diagram elements.

4. heading: "4. Build The Picture"; caption: "The data is combined into maps and images of space."; visual: final panel showing a stylized space map with planets, nebula swirls, star clusters, and a glowing chart overlay, plus a small comparison from raw dots to a finished celestial image, with a bold concluding arrow pointing to the final result.

Connect all stages with bright directional arrows, dotted path lines, and sequence numbers in circular badges; ensure the flow is obvious and easy to follow from stage 1 to stage 4. Include a small legend box with the exact labels "Light", "Signal", and "Data" next to matching simple icons. Visual style: retro 1950s science poster fused with futuristic educational design; optimistic, accessible, informative mood; tech neon cyan and magenta palette with deep navy or charcoal background, cream accent text panels, geometric mid-century shapes, subtle halftone print feel, magazine-grade editorial illustration, vector-clean lines, no photographic textures. No real-brand logos, no copyrighted characters, no identifiable people, no medical diagrams or graphic medical content.
