Leaving space enthusiasts smitten, the National Aeronautics and Space Administration shared a stunning 10-year timelapse of the Sun’s outermost atmospheric layer – the corona by keeping an unblinking watch over it for a decade. As of June 2020, NASA’s Solar Dynamics Observatory had been watching the Sun non-stop and from its orbit in space around the Earth, the SDO had gathered 425 million high-resolution images of the Sun.

Countless new discoveries about the workings of our closest star and how it influences the solar system, enabled after amassing 20 million gigabytes of data over the past 10 years. Showing the rise and fall in activity that occurs as a part of the Sun’s 11-year solar cycle, SDO shared the incredible video with notable events like transiting planets and eruptions.

Compiling one photo of the Sun’s corona every hour, NASA shared the video on its social media handle where a decade of the Sun is condensed into 61 minutes. In a statement released by the space agency, it elaborated that “the dark frames in the video are caused by Earth or the Moon eclipsing SDO as they pass between the spacecraft and the Sun. A longer blackout in 2016 was caused by a temporary issue with the AIA instrument that was successfully resolved after a week. The images where the Sun is off-center were observed when SDO was calibrating its instruments.” Also Read - Mars 2020 Mission: NASA's Perseverance Rover Lifts Off, Begins 7-Month Journey to the Red Planet | Watch
Check out the impressive video here:
The music in the video was composed by musician Lars Leonhard and is titled “Solar Observer.” SDO had captured an image of the Sun every 0.75 seconds with a triad of instruments like the Atmospheric Imaging Assembly (AIA) which alone captures images every 12 seconds at 10 different wavelengths of light.
In order to provide further insights about our place in space and keep our astronauts and assets safe by providing them with adequate information, SDO and other NASA missions will continue to watch our Sun in the coming years.
