Solar Observations Across Wavelengths: SDO HMI & AIA Image Gallery #1851767 (License: Personal Use)

This composite displays solar imagery from NASA’s Solar Dynamics Observatory (SDO), using the Helioseismic and Magnetic Imager (HMI) and Atmospheric Imaging Assembly (AIA) instruments. The images span wavelengths from Doppler velocity and magnetograms (HMI) to extreme ultraviolet channels (AIA 1700 Å to 131 Å), revealing structures like sunspots, active regions, flaring plasma, and the quiet corona. Temperatures range from 4,500 K in the photosphere to over 10 million K in flare loops.

Used on astronomy education sites, NASA outreach pages, or solar physics resources to illustrate multi-wavelength solar observation techniques; matches user intent for learning how different wavelengths reveal solar atmospheric layers and dynamic phenomena.
