Coronal mass ejection

In this composite image of a coronal mass ejection captured by the Solar and Heliospheric Observatory spacecraft, an image of the sun in extreme UV light taken by the Extreme Ultraviolet Imaging Telescope (EIT) around January 4, 2002 was enlarged and superimposed on an image taken by the Large Angle and Spectrometric COronagraph (LASCO) instrument .

Direct sunlight is blocked by the sun here to reveal the surrounding faint corona.
