A corona mass ejection (CME), associated with a solar flare, blew out from just around the edge of the Sun today in a glorious roiling wave (May 1, 2013). The video, taken in extreme ultraviolet light by NASA's Solar Dynamics Observatory spacecraft, covers about 2.5 hours. SOHO's C2 and C3 coronagraphs shows a large, bright, circular cloud of particles heading out into space. STEREO spacecraft, from their different perspectives in space, observed the flare. CME's carry over a billion tons of particles at over a million miles per hour. Credit: NASA/SDO
