Blast from the sun

A huge prominence erupts from the left side of the sun's disk in one of a series of images recorded in the ultraviolet spectrum over a 30-hour period by NASA's STEREO spacecraft. The Sept. 26-27 prominence, which was powered by the sun's magnetic field, was one of the first that was large enough for both of the STEREO (Solar Terrestrial Reflection Observatory) spacecraft to observe it over a period of hours.
