Why Does NASA Observe The Sun in Different Colors?

On February 11, 2010, the Solar Dynamics Observatory, or SDO, spacecraft was launched, and a few months later it started gathering scientific data. The Atmospheric Imaging Assembly and the Helioseismic and Magnetic Imager, which were created in tandem to give complimentary views of the Sun, are two imaging devices that allow SDO to see the Sun in more than 10 different light wavelengths, revealing solar material at various temperatures. Using a method known as helioseismology, SDO also analyzes the Sun's magnetic field and the movement of solar material at its surface. It also enables researchers to see far into the Sun's core, where its intricate magnetic fields originate.
