Solar Atmosphere Layers Explained: Photosphere, Chromosphere, and Corona #59107 (License: Personal Use)

The image details the Sun’s atmospheric structure: the photosphere (5,800 K, emitting white light), the chromosphere (6,000-20,000 K, visible in H-alpha and UV), and the corona (1-3 million K, seen in X-rays and extreme UV). Each layer is paired with its characteristic emission wavelengths (e.g., Fe XII at 19.5 nm, Fe IX/X at 17.1 nm) and associated phenomena like solar magnetic maps and spicules. A transition region between chromosphere and corona marks a sharp temperature rise.

Used in astronomy education, solar physics resources, and science outreach websites to explain solar structure; matches user intent for learning about the Sun’s layers, space weather, or preparing STEM curriculum materials.
