Structure of the Sun: Core to Corona Explained #1851746 (License: Personal Use)

This scientific illustration depicts the Sun’s internal architecture-inner core (blue), radiative zone (green-yellow), and convection zone (orange-red)-alongside its atmospheric layers: photosphere (visible surface), chromosphere (pinkish layer above), and corona (outermost halo). Subsurface flows are shown just beneath the photosphere, illustrating plasma motion that drives solar activity. The color scale reflects increasing temperature from core outward, peaking in the corona despite its low density.

Used in astronomy education, science textbooks, and space agency outreach pages to explain solar physics; targets students, educators, and enthusiasts seeking foundational knowledge of stellar structure and solar phenomena.
