Infografika hvězdného vývoje a planety soustavy

Astronomy infographic titled "Star Lifecycle: Main Sequence" using STAR LIFECYCLE flowchart archetype. Show a clear scientific flow from stellar nebula to protostar to main-sequence branches, emphasizing the main-sequence phase as the central largest panel, then branching into low-mass and high-mass outcomes. Include an explicit label: "Diagram not to scale". Render stars, gas clouds, and remnants with scientifically reasonable colors and proportions for an educational infographic, while noting that sizes and distances are not to true scale. Add 7 labeled callouts in English with canonical scientific names and one accurate fact each: "Stellar Nebula" — "Cold molecular cloud, typical temperature about 10 K"; "Protostar" — "Forms as gravity compresses gas and dust before hydrogen fusion begins"; "Red Dwarf Main-Sequence Star" — "Mass: less than 0.5 solar masses"; "Sun-like Main-Sequence Star" — "Surface temperature: about 5,800 K"; "Massive Main-Sequence Star" — "Mass: more than 8 solar masses"; "Red Giant" — "A Sun-like star can expand to more than 100 times its original diameter"; "Supernova" — "Peak luminosity can briefly outshine an entire galaxy"; "White Dwarf" — "Typical diameter: about 12,000 km"; "Neutron Star" — "Typical diameter: about 20 km". Use scale-aware labels such as "low mass", "solar mass", "high mass", "compact remnant" where appropriate. Add a small scale-reference strip in English: "Sun diameter = 1,392,700 km", "Earth diameter = 12,742 km", "1 solar mass = 1.989 × 10^30 kg". Visual style: editorial NASA-poster, aurora green and violet palette, luminous nebula gradients, crisp vector icons, subtle starfield background, clean arrows, modern scientific typography, high contrast for dark backgrounds, sophisticated and accurate mood for astrophysics enthusiasts. Include 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.
