How Scientists Observe the Sun In Every Possible Way

Illustration for article titled How Scientists Observe the Sun In Every Possible Way

NASA has published this colorful collage that shows the Sun in every possible way using all the instruments from the Solar Dynamics Observatory. Scientists use these views to study different aspects of the Sun's structure and behavior:

Each of the wavelengths observed by NASA's Solar Dynamics Observatory (SDO) was chosen to emphasize a specific aspect of the sun's surface or atmosphere. This image shows imagery both from the Advanced Imaging Assembly (AIA), which helps scientists observe how solar material moves around the sun's atmosphere, and the Helioseismic and Magnetic Imager (HMI), which focuses on the movement and magnetic properties of the sun's surface.
