The Solar and Heliospheric Observatory (SOHO) captured this image of a coronal mass ejection (CME), erupting on the left side of the sun, on Nov. 23, 2012, at 1:30 p.m. EST as it was moving away from the sun into space. This image from SOHO is what's known as a coronagraph, in which the bright light of the sun is blocked in order to make the dimmer structures in the sun's atmosphere, or corona, visible.
