This amazing image is of a sunspot three times the size of the Earth. The photograph was taken using the National Science Foundation's Dunn Solar Telescope at Sunspot, NM, which was recently upgraded with an adaptive optics system. The Dunn telescope has a flexible mirror which can be deformed 130 times a second to compensate for atmospheric distortion. This image was made with 80 individual photographs combined together.
