Galaxy Types Astronomy Infographic | moon phase diagram with sun

Astronomy infographic titled "Galaxy Types" using ORBITAL diagram archetype, designed for an astrophysics enthusiast. Central composition: a hub-and-orbit layout with a luminous core labeled "Galaxy Morphological Types", surrounded by scientifically accurate illustrated examples of major galaxy classes placed on orbital tracks; include a clear caption "Diagram not to scale" because galaxy sizes and distances are comparative only. Render each galaxy with realistic morphology, structure, dust lanes, star-forming regions, halo glow, and color appropriate to stellar populations in a photorealistic cosmic style. Include 6 labeled callouts, each with canonical scientific name and one accurate fact in English: "Elliptical Galaxy (E0-E7)" — "Typical diameter: 10 000-300 000 light-years"; "Lenticular Galaxy (S0)" — "Disk galaxy with little ongoing star formation"; "Spiral Galaxy (Sa-Sd)" — "Typical diameter: about 30 000-200 000 light-years"; "Barred Spiral Galaxy (SBa-SBd)" — "Central bar channels gas toward the nucleus"; "Irregular Galaxy (Irr)" — "No stable spiral or elliptical structure"; "Dwarf Galaxy" — "Typical stellar mass: about 10^7-10^9 solar masses". Add small secondary annotations near representative examples: "Milky Way — Barred spiral galaxy"; "Andromeda (M31) — Diameter: about 220 000 light-years"; "Large Magellanic Cloud — Distance from Milky Way: about 163 000 light-years". Add a compact comparison legend showing shape classes and a small scale-reference strip in English: "Reference: Milky Way diameter = about 100 000 light-years". Include subtle metric tags such as "stellar population", "gas and dust content", and "star formation rate" in clean editorial labels. Visual style: photorealistic cosmic, nebula purple & cyan palette, high contrast on dark background, soft volumetric glow, editorial astronomy illustration, dark-mode-friendly cosmic palette, vector-clean infographic layout. No astrology framing, no UFO / pseudoscience imagery. 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.
