Last month, the biggest sunspot in 22 years traversed across the Sun. Labelled AR 2192, it was big enough to see without the need for a telescope. This awesome timelapse animation can show you what you missed. Created by processing 72GB of data from NASA's solar dynamics lab, the video is a composite of more than 17,000 images, rendered in 4K and set to the 'sun's heartbeat'. It definitely gives an incredible sense of the size and fluidity of the sun. via Sploid.
