Incandescent Sun

This video takes SDO images and applies additional processing to enhance the structures visible. While there is no scientific value to this processing, it does result in a beautiful, new way of looking at the sun. The original frames are in the 171 Angstrom wavelength of extreme ultraviolet which shows plasma at around 600,000 Kelvin. The video covers 24 hours of activity on September 25, 2011.
