Sun's surface at different wavelengths. Composite image of the Sun's surface and atmosphere viewed using visible light and nine different wavelengths
Sun's surface at different wavelengths. Composite image of the Sun's surface and atmosphere viewed using visible light and nine different wavelengths of ultraviolet light, as seen by NASA's Solar Dynamics Observatory (SDO). The visible light is recorded by the HMI (Helioseismic and Magnetic Imager) sensor, while the ultraviolet images (segments) are from the Atmospheric Imaging Assembly (AIA) sensor. The main image (orange, across bottom) is the HMI visible light observation at nanometres (nm). The ultraviolet wavelengths are (clockwise from left): 170 nm (pink), 160 nm (green), nm (blue), nm (orange), nm (violet), nm (bronze), nm (gold), nm (aqua) and nm (green). Image published in 2013.
