Incredible 10-Year Time Lapse of Sun From NASA’s Solar Dynamics Observatory

Of course, the SDO couldn't fix its gaze on the Sun 100 percent of the time.

The SDO mission has collected some 20 million gigabytes of data since its launch in February 2010.

Till the end of the decade, SDO had utilised total of 20 million GB of space to capture 435 million high resolution images of the Sun.

The video shows the Sun moving between its maximum and minimum phases. The photos featured in the video were captured using the SDO's Atmospheric Imaging Assembly (AIA) instrument, which is capable of capturing images every 12 seconds under 10 different light wavelengths. The Sun has been under the watch of NASA's Solar Dynamics Observatory (SDO) for over a decade, a release from NASA said.

Aside from the corona, other notable solar features and events can also be spotted in the video.

Images from the SDO are produced by capturing only a specific ultraviolet wavelength that lets scientists see the star's corona, which is its outermost layer.

Another puzzling shaking effect is seen just after 57 seconds, which was unexplained by NASA, while the camera briefly goes offline in the 38th minute. There are also frames in the video that showcase rare instances during which planets pass between the observatory and its fiery quarry.

A longer blackout in 2016 was also caused by a temporary issue with the probe's AIA instrument.

Extreme Ultraviolet Variability Experiment (EVE), meanwhile, measures fluctuations in the Sun's ultraviolet output. To this end it was equipped with three cutting edge scientific instruments capable of probing a range of processes occurring in and around the Sun, including keeping track of its magnetic field and the nature of the stellar wind that streams throughout our solar system.

Helioseismology, a term coined by British astronomer Douglas Gough, is the study of the solar interior using observations of waves on the Sun's surface.

The space agency has an online library of the SDO's greatest shots in the last decade, including unusual plasma tornados in 2012 and dark patches called "coronal holes" where extreme ultraviolet emission is low.
