NASA just released epic 10-year timelapse of Sun

NASA unveils 10 years of solar activity in stunning time lapse video

In these 10 years, the SDO has accumulated more than 20 million gigabytes of data for scientists to analyse. The Sun has been under the watch of NASA's Solar Dynamics Observatory (SDO) for over a decade, a release from NASA said.

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.

"A Decade of Sun" condenses 425 million high-definition images, snapped once every 0.75 seconds within the period of June 2, 2010 and June 1, 2020.

The Atmospheric Imaging Assembly (AIA) instrument alone captures images every 12 seconds at 10 different wavelengths of light.

And though NASA's SDO has watched the Sun without respite for 10 years, there are notable anomalies during the time-lapse.

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.


NASA has released a stunning 10-year time-lapse video of the Sun, bringing a decade of activity into a one-hour film. Apart from the rise and fall in the activity of the Sun, the video might also help space scientists gather new information about the transiting planets and other eruptions in the Solar system. 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.

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

While an instrument failure resulted in a longer blackout in 2016.

The custom music, titled "Solar Observer", was composed by musician Lars Leonhard.

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