The picture that cropped image was taken from is from the Solar Dynamics Observatory, a NASA satellite stationed between the Earth and the Sun to capture information about sunspots (a few are visible toward the bottom of the image), coronal mass ejections, and other solar phenomena. The pictures alone are priceless, I think.
