It's amazing to see how different the sun looks depending on the filters you use. Here you can see it in ultraviolet light, looking as evil as the darkest pits of Mordor. I imagine those sinuous filaments are nefarious serpents made from the souls of dead evil people.

Shown in ultraviolet light, the relatively cool dark regions have temperatures of thousands of degrees Celsius. Large sunspot group AR 9169 from the last solar cycle is visible as the bright area near the horizon. The bright glowing gas flowing around the sunspots has a temperature of over one million degrees Celsius.
