NASA Sees a Circular Coronal Mass Ejection (video) NASA/Goddard Space Flight Center Share Print E-Mail Loading video... Caption A coronal mass ejection (CME) erupted from just around the edge of the sun on May 1, 2013, in a gigantic rolling wave. CMEs can shoot over a billion tons of particles into space at over a million miles per hour. This CME occurred on the sun's limb and is not headed toward Earth. The video, taken in extreme ultraviolet light by NASA's Solar Dynamics Observatory (SDO), covers about two and a half hours.
