On the left we see a series of magnetic loops on the sun as captured by NASA's Solar Dynamics Observatory on July 18, 2012.
The image on the right has been processed to better define the edges of each loop, called flux rope, and further define the structures which are at the center of coronal mass ejections.
This is the first time scientists were able to discern the timing of a flux rope's formation.
