Solar Fireworks

January 26, 2013
The second of two coronal mass ejections (CMEs) on Jan. 23, 2013, is seen erupting in the top of the picture, away from the sun, which is obscured by the disk in the center. The Solar and Heliospheric Observatory captured this image, called a coronagraph: the bright light of the sun itself is blocked to provide a better view of the sun's atmosphere, the corona. This CME left the sun at speeds of 375 miles per second (1.35 million mph), which is almost 10 times lower than the very fastest CMEs.
