NASA’s Solar Dynamics Observatory captured these images of a solar flare – as seen in the bright flash on the left – on May 5, 2015. Each image shows a different wavelength of extreme ultraviolet light that highlights a different temperature of material on the sun. By comparing different images, scientists can better understand the movement of solar matter and energy during a flare. From left to right, the wavelengths are: visible light, 171 Angstroms, 304 Angstroms, 193 Angstroms and 131 Angstroms. Each wavelength has been colorized. Unlabeled.
