Comet Anatomy Astronomy Infographic | venus in d9

Astronomy infographic titled "Comet Anatomy" using a STAR LIFECYCLE flowchart adapted into a scientific structure-and-evolution sequence for a comet, for a general public audience. Show a left-to-right flowchart of a comet approaching the Sun: distant inactive nucleus in the Kuiper Belt / Oort Cloud context, warming active comet, coma formation, dust tail, ion tail, and inner solar system passage. Include a clear label "Not to scale" on the main diagram because comet sizes, coma widths, tail lengths, and orbital distances are not shown at true scale. Render scientifically reasonable proportions and colors: dark irregular nucleus, bright icy jets, diffuse greenish coma, curved pale dust tail, straight blue ion tail pointing away from the Sun, small inset Sun to indicate solar radiation and solar wind direction. Add 7 labeled callouts with exact English labels and one accurate fact each: "Nucleus — solid core, typically about 1 to 20 km wide"; "Coma — diffuse gas cloud that can expand to more than 100,000 km across"; "Dust Tail — sunlight pushes dust into a broad curved tail"; "Ion Tail — charged gas forms a straighter tail directed away from the Sun by the solar wind"; "Jets — localized outgassing occurs when surface ices sublimate"; "Water Ice — sublimation begins strongly as a comet nears the inner Solar System"; "Organic Compounds and Dust — comets preserve primitive material from early Solar System formation about 4.6 billion years ago". Add a small scale-reference strip in English with: "Reference: nucleus 10 km | coma 100,000 km+ | tail can extend millions of km". Include subtle flowchart arrows labeled "Heating", "Sublimation", "Outgassing", "Tail Formation". Visual style: editorial NASA-poster, aurora green & violet palette, dramatic but educational, high-contrast typography, clean scientific icons, 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.
