Vídeo de Sunspot activity with Earth overlay

"Time-lapse sequence spanning several days showing sunspot activity photographed from the Swedish Solar Telescope on La Palma in the Canary Islands with silhouette of Earth overlaid. Sunspots appear dark because they are cooler than the surrounding surface due to strong magnetic fields that cause bottlenecks that prevent the Sun's core heat from reaching the surface. The average sunspot is about 4, 500 degrees C while the surrounding area is about 6, 000 degrees C. Sunspots can last for weeks or more and can reach 80, 000 km across which is equivalent to six planet Earths. The darkest area of the large sunspot featured here is about 15, 000 km across which is large enough to swallow the Earth. The sunspots are surrounded by smaller convections cells called granules which are roughly 1, 500 km in diameter."
