File:Coronal Mass Ejection.gif
Summary
Arcs rise above an active region on the <a href="//commons.wikimedia.org/wiki/Category:Surfaces" title="Category:Surfaces">surface</a> of the <a href="//commons.wikimedia.org/wiki/Sun" title="Sun">Sun</a> in this series of images taken by the STEREO (Behind) spacecraft. The arcs are plasma, superheated matter made up of moving charged particles (<a href="//commons.wikimedia.org/wiki/Category:Electron" title="Category:Electron">electrons</a> and ions). Just as <a href="//commons.wikimedia.org/wiki/Iron" title="Iron">iron</a> filings arc from one end of a <a href="//commons.wikimedia.org/wiki/Magnet" title="Magnet">magnet</a> to another, the plasma is sliding in an arc along magnetic field lines. Most coronal mass ejections are more bulbous and wide: this one is quite narrow and contained. Nonetheless, <a href="//commons.wikimedia.org/wiki/NASA" title="NASA">NASA</a> solar scientists agree that its speed and characteristics suggest that it was indeed a non-typical coronal mass ejection.
