Tableau système solaire style infographie des types de galaxies

Astronomy infographic titled "Galaxy Types"; GALAXY anatomy comparison infographic adapted as a set of profile-card panels for the general public, showing the major galaxy classes side by side in a scientifically accurate comparative layout. Main composition: 5 elegant labeled galaxy cards arranged in a clean grid on a dark background, each card featuring a detailed illustrated galaxy portrait with a small scale-aware caption and one accurate scientific fact; include a visible note reading "Diagram not to scale" because galaxy sizes and distances are comparative, not true scale. Cards and callouts to include: 1) "Elliptical galaxy (E0-E7)" — smooth ellipsoidal stellar distribution, little cold gas or dust, key fact: "Typical diameter: 30,000-300,000 light-years". 2) "Spiral galaxy" — flat rotating disk, central bulge, spiral arms rich in gas and young stars, key fact: "Milky Way diameter: about 100,000 light-years". 3) "Barred spiral galaxy" — central bar feeding spiral arms, canonical example shown structurally distinct, key fact: "The Milky Way is classified as a barred spiral galaxy". 4) "Lenticular galaxy (S0)" — disk plus bulge but weak or no spiral arms, intermediate morphology, key fact: "Contains less interstellar gas than most spiral galaxies". 5) "Irregular galaxy" — asymmetric form without stable spiral or elliptical structure, key fact: "Large Magellanic Cloud diameter: about 14,000 light-years". Add 2 more small labeled comparison callouts around the central layout: "Dwarf galaxy" — "Typical stellar mass: 10^7-10^9 solar masses" and "Giant elliptical" — "Can contain more than 10^12 stars". Include 5-9 total labeled callouts with canonical scientific wording and accurate facts. Add subtle annotation lines identifying structural features in the spiral and barred spiral examples: "Central bulge", "Spiral arms", "Bar", "Halo", "Dust lanes". Include a small scale-reference strip in English at the bottom with examples such as: "Milky Way diameter = about 100,000 light-years", "Andromeda diameter = about 220,000 light-years", "Large Magellanic Cloud diameter = about 14,000 light-years". Visual style: vintage astronomy plate, sunset warm cosmic palette, copper, amber, muted rose, deep plum, sepia-gold highlights, finely shaded editorial star atlas engraving feel blended with modern clarity; calm educational mood, high legibility, textured paper-grain effect, thin ornamental borders, elegant legends, editorial astronomy illustration, dark-mode-friendly cosmic palette, vector-clean infographic layout. No planets or moons as the main subject; use galaxy morphology as the true content despite the profile-card presentation. 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.
