Few months ago, the major sunspot in 22 years traversed through the Sun. Named AR 2192, it was giant enough to observe without the necessity for a telescope. Produced by processing 72GB of files from NASA's solar dynamics lab, the video is a compound of more than 17,000 images, condensed in 4K and set to the 'sun's heartbeat'. It absolutely gives an unbelievable sense of the magnitude and variability of the sun. This splendid timelapse animation can show you what you overlooked or missed.
