Structure of the Sun: Layers, Dimensions, and Solar Features Explained #1851754 (License: Personal Use)

This scientific illustration reveals the Sun’s layered architecture: a dense core (175,000 km radius) where nuclear fusion occurs, surrounded by the radiative zone (500,000 km), convective zone (200,000 km), and visible surface layers-the photosphere (300 km thick), chromosphere, and expansive corona extending up to 2 million km. Labels in Czech identify features such as sunspot groups (sluneční skvrny), solar prominences (protuberance), and granulation patterns, with Earth’s size shown for scale at the bottom left.

Used in astronomy education, science textbooks, or planetarium exhibits to explain solar physics; targets students, educators, and space enthusiasts seeking visual comprehension of stellar structure and solar activity.
