These are recordings that have never been seen before: A NASA video shows the sun’s activity over the past ten years in a time-lapse video within an hour.

The images were recorded using an instrument called the Atmospheric Imaging Assembly (AIA) on board the “Solar Dynamics Observatory” (SDO).

Here you can see the video:

In the video, the heat-glowing sphere rotates calmly around itself. In the background: the black of space. Only sometimes does the picture shake, such as 2012, when Venus passed the sun, as reported by krone.at. The phenomenon repeated itself in 2017. When the sun briefly disappears in the video, “the earth or the moon obscured the SDO as they moved between the satellites and the sun,” said Nasa.

20 million gigabytes of data were collected for the project. The artist Lars Leonhard composed the piece “Solar Observer” for the video and, if everything goes well, you will hear it again in 2030 for another review. That’s how long SDO should be in use. – kse
