High-Resolution UV Image of the Sun - Solar Activity & Coronal Features #1661082 (License: Personal Use)

Captured by NASA’s Solar Dynamics Observatory (SDO), this ultraviolet image reveals the Sun’s outer atmosphere at a wavelength of 171 Å, emphasizing million-degree plasma trapped in magnetic loops. Bright regions indicate active sunspots and emerging flux, while darker areas represent cooler coronal holes. The image provides critical data for space weather forecasting and solar physics research.

Used on astronomy, space science, and educational websites to illustrate solar dynamics, space weather, or heliophysics concepts; targets users seeking scientific imagery, classroom resources, or科普 content about the Sun.
