With its C2 coronagraph instrument, NASA's satellite SOHO captured a blossoming coronal mass ejection (CME) as it roared into space from the right side of the Sun (Dec. 28, 2013).

This technique strongly emphasizes the changes that occurred. Here we have taken a single white light frame and shift it back and forth with a running difference image taken at the same time to illustrate the effect. Credit: NASA/GSFC/SOHO …
