NASA celebrated the 10th anniversary of its Solar Dynamics Observatory (SDO) with a breathtaking time-lapse video that shows the development of the solar atmosphere during this period.
The video compresses photos to 61 minutes in a decade, with individual images an hour apart. Some memorable events can be seen in the film, such as the transit of the planet Venus, which took place on June 5, 2012.
The SDO mission has collected around 20 million gigabytes of data since its launch in February 201
The photos used for the time-lapse video were created by the Atmospheric Imaging Assembly – a multi-channel imaging device used for observations on full disks. They were taken in an extreme ultraviolet region of the spectrum, which is well suited for studying the corona, the outermost layer of the sun’s atmosphere.
