The Sun's hot and "cold" atmosphere - AIA
May 17, 2012
AIA's many wavebands allow us to see regions on the Sun corresponding to a range of temperatures. The first image is a composite made from three of the AIA wavelength bands, corresponding to temperatures from .7 to 2 million degrees (hotter = red, cooler = blue). The second movie shows a prominence eruption made showing 50,000 and 700,00 degrees.
