Solar Dynamics Observatory Shows Sun's Rainbow of Wavelengths...epa03995749 An undated handout picture released by NASA on 19 December 2013 shows a still image taken from a NASA movie of the sun based on data from NASA's Solar Dynamics Observatory (SDO), showing the wide range of wavelengths, invisible to the naked eye, that the telescope can view. SDO converts the wavelengths into an image humans can see, and the light is colorized into a rainbow of colors. Yellow light of 5,800 Angstroms, for example, generally emanates from material of about 5,700 degree Celsius, which represents the surface of the sun. Extreme ultraviolet light of 94 Angstroms, which is typically colorized in green in SDO images, comes from atoms that are about 6,300,000 degree Celsius and is a good wavelength for looking at solar flares, which can reach such high temperatures. By examining pictures of the sun in a variety of wavelengths, as it is done not only by SDO, but also by NASA's Interface Region Imaging Spectrograph, NASA's Solar Terrestrial Relations Observatory and the European Space Agency/NASA Solar and Heliospheric Observatory; scientists can track how particles and heat move through the sun's atmosphere.
