NASA's 10-year time-lapse of Sun leaves netizens awestruck

Still, every decade that our old sun burns on is a decade of turbulent, sometimes violent change - a fact that becomes beautifully evident in a new time-lapse video from NASA's Solar Dynamics Observatory (SDO).

The Atmospheric Imaging Assembly (AIA) instrument, for instance, takes a snapshot in 10 different wavelengths of light every 12 seconds.

"This information has enabled countless new discoveries about the workings of our closest star and how it influences the solar system".

The SDA mission of NASA was launched in the year 2010 to understand the origin of Sun's energy.

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

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.

Titled "A Decade of Sun", the video was released on Wednesday. It accomplishes these tasks by determining how the Sun's magnetic field is generated, and how this stored magnetic energy is converted and released into the heliosphere and geospace in the form of solar wind, energetic particles, and aberrations in the solar irradiance. The video condenses ten years of data into a 61-minute, showing the rise and fall in solar activity over the 11-year solar cycle along with eruptions and event planet transitions.

NASA has been recorded the Sun for over 10 years now, and to celebrate that achievement it has released a 10-year time-lapse video.

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

The video features a custom soundtrack, "Solar Observer" which was composed by musician Lars Leonhard.

The images where the Sun is off-center were observed when SDO was calibrating its instruments.
