Solar flare in various wavelengths

On July 19, 2012, SDO captured images of a solar flare in numerous wavelengths. The 131 Angstrom wavelength, shown here in the middle and colorized in teal, portrays particularly hot material on the sun, at 10 million Kelvin, which is why the incredibly hot flare shows up best in that wavelength.

The 131 wavelength was also able to show kinked magnetic fields known as a flux rope that lay at the heart of a coronal mass ejection, which also erupted at the same time as the flare.
