Yet an another incredible 61-minutes time lapse movie from NASA is drawing attention of millions of users across social media.



Recently on 24 June 2020, NASA's Goddard space flight center shared an incredible 61-minutes time lapse movie with public called 'A decade of Sun'. Now, this video is trending on social media with more than 1.2 million views and 12 thousand likes.

"The SDO captured 425 million High resolution images of the Sun since last 10 years which taken 20 million gigabytes of data to store. The High quality instruments used in SDO helped NASA to capture images of the Sun for every 0.75 Seconds. Atmospheric Imaging Assembly (AIA) captured images for every 12 seconds at 10 different wavelengths of light. Actually, this movie is a 10 year time lapse of the photos taken at a wavelength of 17.1 nanometers, which is extreme ultraviolet wavelength showing the Sun's outermost atmospheric layer called Corona" NASA said.

This video is made from the combination of one photo every hour for a total of 10 years giving a 61 minutes movie. It shows the dynamic activity of the Sun occurs as a part of Sun's 11 years solar cycle. The SDO unceasingly observing the Sun since its launch, on 11 February 2010.

The custom music used in the movie titled as the ‘Solar Observer’, was composed by Lars Leonhard.
This video is made from the images captured between 2 June 2010 to 1 June 2020, but SDO missed few moments due to the Earth and moon eclipsing as they pass between the Sun and SDO.

As we can watch the Venus transit at 12 minutes 24 seconds, Partial solar eclipse at 2 minutes 17 seconds and a long blackout at middle of the video due to temporary issue with AIA instrument in 2016.
While the people watching this video are stunned.
