Solar EjectionMaterial from the sun's surface stretches high into its atmosphere in a combined picture of an extremely bright coronal mass ejection seen on February 28 by NASA's STEREO spacecraft.

Released on March 5, the new picture combines a STEREO view of the sun (orange) with a picture from the craft's coronograph, which blocks out the sun's glare to capture the fainter light of the sun's upper atmosphere, or corona (green).
