NASA Releases Stunning 10-Year Time-Lapse Of The Sun

In order to capture the Sun's movement, scientists use special devices, such as the Solar Dynamics Observatory (SDO) which is created to keep an eye on the star.

The SDO mission of NASA was launched in the year 2010 to understand the origin of Sun's energy, how the inside of the Sun works, and how energy is stored and released in the Sun's atmosphere. "SDO has gathered 425 million high-resolution images of the Sun, amassing 20 million gigabytes of data over the past 10 years. 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.

But the space probe is home to many different instruments and not just one powerful camera.

NASA said: "This 10-year time-lapse showcases photos taken at a wavelength of 17.1 nanometers, which is an extreme ultraviolet wavelength that shows the Sun's outermost atmospheric layer - the corona".

This week the Centers for Disease Control and Prevention estimated that for every reported case, there were 10 other infections. China, New Zealand and Australia have seen new outbreaks in the past month, despite largely stifling local transmission.

The photos used for the time-lapse video were made by the Atmospheric Imaging Assembly - a multichannel imaging device used for full-disc observations.

The time lapse footage is believed to hold much value for the scientists who are interested in knowing about the functioning of the Sun and rise and fall in its activity during its 11 year solar cycle.

During that decade, the sun undergoes a sea change, slowly bubbling with enormous magnetic ripples known as sunspots, which peaked around 2014 before fading away again.

The custom music, titled "Solar Observer", was composed by musician Lars Leonhard. An instrument failure in 2016 resulted in a longer blackout. Occasional frames where the Sun disappears entirely or appears off center represent periods during which the probe was forced to take a quick break from stargazing in order to re calibrate its delicate instruments.
