Wheel of Colorful Sun - SDO 5 Years

The power of AIA lies in its ability to constantly image the entire solar atmosphere in multiple wavelengths. This composite image reveals some of that potential: Each color represents a different wavelength of extreme ultraviolet light present in the sun's corona. The wavelengths in turn correlate to material of different temperatures, resulting sometimes in completely different views of the same sun.

Scientists examine the combined images to reveal the solar atmosphere in all its detail.
