The image is generated by the Solar and Heliospheric Observatory (SOHO) spacecraft, which sits part way between Earth and the Sun. The LASCO (Large Angle Spectrometric Coronagraph) instrument on SOHO makes images like this one by blocking the light coming directly from the Sun with an occulter disk, creating an artificial eclipse within the instrument itself. The position of the solar disk is indicated in the images by the white circle. SOHO is a project of international cooperation between ESA and NASA. | About this solar image This real-time movie, which shows the most recent 48 hours of solar activity, is updated every hour if satellite communications permit. The image is generated by the Solar and Heliospheric Observatory (SOHO) spacecraft. The image shows magnetic activity in the Sun's corona. The most prominent features are usually the coronal streamers, nearly radial bands streaming outward. Occasionally, the Sun belches a giant coronal mass ejection, an explosion of charged particles that unfurl as they area hurled into space. The inner solar corona is seen up to 8.4 million kilometers (5.25 million miles) away from the Sun. The corona is the Sun's outer atmosphere, where the density of matter is low but temperatures are high. (For more, see Space Weather 101.) -- Robert Roy Britt More SPACE.com Cams Don't Miss ...
