Closeup of Comet Encke from STEREO

This is a closer view of Comet Encke's collision with a Coronal Mass Ejection (CME) as seen by the STEREO satellite on April 20, 2007. The collision is notable because it completely removed Encke's tail. The blue color here is a gradient added to help make the comet and CME more visible.
