zodiac sun moon and rising Star Lifecycle Main Sequence

Astronomy infographic titled "Star Lifecycle: Main Sequence" using an ORBITAL diagram archetype, redesigned as a scientifically accurate educational diagram for high school students: central glowing yellow-white main-sequence star, surrounded by orbital-style concentric annotation rings that explain the main-sequence phase within stellar evolution, with clear English label "Not to scale" placed near the diagram because stellar sizes, lifespans, and comparison distances are schematic. Show the central diagram with realistic stellar color and scientifically reasonable structure: hydrogen fusion in the core, radiative zone, convective zone, photosphere, and outward energy flow. Add 7 labeled callouts in English, each with canonical scientific naming and one accurate fact: "Protostar — Forms from a collapsing molecular cloud; core temperature rises toward 10 million K before sustained fusion.", "Main-sequence star — Stable hydrogen fusion in the core; the Sun remains in this stage for about 10 billion years.", "Red dwarf (M-type main-sequence star) — Mass: about 0.08-0.6 solar masses; lifespan can exceed 1 trillion years.", "Sun-like star (G-type main-sequence star) — Surface temperature: about 5,778 K.", "Blue giant main-sequence star (O-type or B-type) — Mass can exceed 10 solar masses; lifespan is only a few million years.", "Hydrogen fusion core — 4 hydrogen nuclei fuse into helium, releasing energy.", "Habitable-zone example orbit — Around a Sun-like star, Earth orbits at 1 AU = 149.6 million km." Include scale-aware labels where relevant such as "Radius: 1 solar radius" for the Sun-like star, "Lower mass, smaller radius" for red dwarf, and "Higher mass, larger radius" for blue main-sequence star. Add a small English scale-reference strip at the bottom: "Sun diameter = 1,392,700 km", "Earth diameter = 12,742 km", "1 AU = 149.6 million km". Visual style: photorealistic cosmic rendering blended with vector-clean infographic structure, luminous nebula background in purple and cyan, crisp rings, subtle starfield, high contrast dark-mode-friendly layout, educational editorial composition, precise legends and clean callout lines, editorial astronomy illustration, dark-mode-friendly cosmic palette, vector-clean infographic layout. 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 UFO / pseudoscience imagery, no watermarks Scientifically accurate facts, no UFO / pseudoscience imagery, no astrology framing. Sizes and distances are typically not to true scale — label as such.
