The NASA He returns to give us another impressive video, this time the product of his 10-year work taking photographs of the Sol. How to get a little closer to the incredible universe that surrounds our planet land.
He Solar Dynamics Observatory NASA (SDO) has been observing the Sun non-stop for more than a decade. From its orbit in space around Earth, SDO collected 425 million high-resolution images of the Sun, accumulating 20 million gigabytes of data in the past 10 years.
This information enabled countless new discoveries about how our closest star works and how it influences the solar system, according to the Nasa.gov site.

The NASA report gives technical details of how he produced this incredible work: he did it through three instruments, capturing an image of the Sun every 0.75 seconds.
The Atmospheric Imaging Assembly (AIA) instrument captured images every 12 seconds at 10 different wavelengths of light. This 10-year time span shows photos taken at a wavelength of 17.1 nanometers, which is an extreme ultraviolet wavelength showing the Sun’s outermost atmospheric layer – the corona. Compiling a photo every hour, the film condenses a decade of the Sun in 61 minutes.

He documented the cycles for a decade. And he condensed them into a 61-minute video. Look.

As explained by NASA on its website, the video shows the increase and decrease in activity that is part of the 11-year solar cycle, so it can be seen that the stage that the Sun is going through at the moment is perfectly normal and occurs regularly.
The film has as background the personalized music, titled “Solar Observer”, composed by the musician Lars Leonhard.
