For the past three years, NASA’s Solar Dynamics Observatory (SDO) has continuously observed and documented the sun’s activity from space, taking an image of the sun every 12 seconds across 10 different wavelengths.
And now we get to take advantage of some of that data (estimated at about 1.5 TB every single day) through this incredible video put together into a “time-lapse” with two images of the sun from each day.
“SDO’s Atmospheric Imaging Assembly captures a shot of the sun every 12 seconds in 10 different wavelengths.
The images shown here are based on a wavelength of 171 angstroms, which is in the extreme ultraviolet range and shows solar material at around 600,000 kelvins (about 1.08 million F).
In this wavelength it is easy to see the sun’s 25-day rotation as well as how solar activity has increased over three years.” – NASA
