NASA published yesterday on Youtube a video of 30 minutes of the Sun at 4K resolution – 4 times the FullHD. AS images were captured from the Solar Dynamics Observatory (SDO – Solar Dynamic Observatory), which records images of the star constantly. The video can be viewed below (or click here to view on Youtube).
The maximum video resolution 4K (3840×2160 pixels), but it’s worth a little assitir even if your monitor – as the vast majority of monitors in the market today – does not support this resolution. The detailed images and the soundtrack for Lars Leonhard create a very immersive experience.
The SDO records images of the star in ten different wavelength bands – which accounts for the color changes that occur throughout the video. Each of these groups, according to NASA, helps highlight solar material at different temperatures
