Our Sun is highly active. At about 4.5 billion years old, it influences nearly everything in the solar system, from the smallest Earthly organisms to the biggest planets.
This image is a blend of 10 wavelengths taken every 12 seconds by our Solar Dynamics Observatory (SDO) in 2015. The mission's 100 millionth image is part of this blend. Along with a fleet of other spacecraft, SDO keeps an eye on the Sun. It tracks changes in its atmosphere, interior, and records space weather like solar flares that can reach Earth.
Image description: A mosaic image of the Sun in different wavelengths shows the swirling surface of the Sun in yellow, red, orange, and purple. Some areas of the star appear black, while light dances off the its atmosphere.
