From Astronomy Pic of the Day comes this fascinating shot of a CME (Coronal Mass Ejection), a comet, and your planet.
The Comet PanSTARRS, which brightened and was visible for the papal election process (along with another comet, by the way…. two comets as Benedict stepped down and Francis was elected…. portentous?). On March 13 finds , finds comet PanSTARRS in a view with Earth seen from the STEREO Behind spacecraft. On the left you see an enormous coronal mass ejection (CME) is erupting from a solar active region. The CME, comet, and Earth are at different distances from the spacecraft. (The comet is closest.) This is a flattened stereo image.
