Raw video: NASA sees massive filament erupt on Sun

A long filament erupted on the sun on August 31, 2012, shown here in a movie captured by NASA's Solar Dynamics Observatory (SDO) from noon EDT to 1:45 a.m. the next morning. 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 were witness to the associated coronal mass ejection (CME) and their views are shown, as well. Credit: NASA
