This is a picture of the sun by the STEREO-B spacecraft. The dark disk in front of it is actually the moon. The sun is purple because the photo was taken in four wavelenghts of extreme ultraviolet light. STEREO-B has a sister ship STEREO-A. STEREO-B lags behind earth while STEREO-A orbits a million miles ahead. The big gap allows the spacecrafts to take pictures of the same scene of the sun at slightly dirrerent angles to allow the production of 3D stereo movies of solar storms.
