Ten years of solar activity in an impressive video courtesy of the SDO observatory

425 million high resolution images of the Sun and 20 million gigabytes of data have been summarized in [this splendid video] (NASA’s Solar Dynamics Observatory (SDO)) courtesy of NASA’s Solar Dynamics Observatory (SDO), after a decade of service.

You can see the ten-year time-lapse below.

Solar Dynamics Observatory

SDO captures an image of the Sun every 0.75 seconds . Only the AIA (Atmospheric Imaging Assembly) instrument captures images every 12 seconds at 10 different wavelengths of light.

The video consists of photos taken at a wavelength of 17.1 nanometers, which is an extreme ultraviolet wavelength that shows the outermost atmospheric layer of the Sun: the corona . The video shows the rise and fall of activity that occurs as part of the Sun’s 11-year solar cycle.

The music, entitled "Solar Observer", has been composed expressly by musician Lars Leonhard .
