Sun’s north pole

North Pole of the Sun as photographed by the SECCHI Extreme UltraViolet Imager (EUVI) mounted on the STEREO-B spacecraft

Recent missions by NASA have provided us with brand new and unique views of the Sun. These three dimensional views of structures in the Sun’s atmosphere have resulted in an increased understanding of solar physics and better space weather forecasting. The above picture is the “virtual left eye” image of the Sun’s north pole; taken by SECCHI Extreme UltraViolet Imager (EUVI) mounted on the STEREO-B spacecraft. STEREO-B is located behind the Earth and follows it in orbit around the Sun while STEREO-A is ahead of the Earth, leading it around the Sun. The EUVI imager is sensitive to wavelengths of light in the extreme ultraviolet portion of the spectrum (including bands at wavelengths of 304, 171 and 195 Angstroms).
