An instrument on our Solar Dynamics Observatory (SDO) captured its 100 millionth image of the sun. The instrument is the Atmospheric Imaging Assembly, or AIA, which uses four telescopes working parallel to gather eight images of the sun – cycling through 10 different wavelengths -- every 12 seconds.

This is a processed image of SDO multiwavelength blend from Jan. 19, 2015, the date of the spacecraft's 100th millionth image release.
