Till now, the SDO has observed the Sun for over 10 years non-stop, gathering 425 million high-resolution images and collecting 20 million gigabytes of data.

In a stunning hour-long video, NASAs sun-pointing semi-autonomous spacecraft, the Solar Dynamics Observatory, has put together a time lapse of its 10 years of observing the Sun. "This information has enabled countless new discoveries about the workings of our closest star and how it influences the solar system", NASA said in a release.

Launched on February 11, 2010 from Cape Canaveral, SDO's mission is to study how solar activity is created and how Space Weather is spawned out of that intense activity that disrupt's Earth's technology systems and communications networks.

The Solar Dynamic Observatory of NASA has been looking over the Sun's activities for the past decade every day.

Equipped with a trio of sensitive instruments, the SDO's brilliant ten-year time lapse short spotlights photos taken at a wavelength of 17.1 nanometers, which is an extreme ultraviolet wavelength that unveils the Sun's outermost atmospheric layer, the shimmering corona.

The video captures the Sun over a period of 10 years into 61 minutes, compiling one photo per hour.

A number of particularly noteworthy solar events that are part of the Sun's 11-year solar cycle are captured in the video, including eruptions, flares, explosions, prominences, etc.

A few dark frames are caused by the Moon or Earth briefly eclipsing the Sun.

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

With a triad of instruments, SDO captures an image of the Sun every 0.75 seconds.

The custom music, titled "Solar Observer", was composed by musician Lars Leonhard. At some moments in the video the sun moves off centre, this is due to the SDO calibrating its instruments.
