This composite image of the Sun reveals the entire solar atmosphere in multiple wavelengths.
This is an awesome image of the Sun through SDO’s many filters. It is one of my favorites.
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.
