X-ray image of the Sun showing a pre-CME sigmoid (left inset) evolving into a post-CME arc (right inset). The main image shows the sun in X-rays, highlighting regions where solar explosions originate, specifically S-shaped regions where magnetic fields interact. The images illustrate the process of a Coronal Mass Ejection (CME).
