Solar Dynamics Observatory images solar filment leaving Sun

A long filament erupted on the sun on 31 August  2012.  The occurrence was captured by NASA's Solar Dynamics Observatory (SDO). The filament lies in the lower left corner of the sun. The movie shows light at 304 Angstroms and 171 Angstroms, both of which help scientists observe the sun's atmosphere, or corona. STEREO and SOHO also observed the associated coronal mass ejection (CME) and their views are shown, as well. Clip courtesy: NASA
