Coronal mass ejection is an exploding bubble of plasma, charged particles, and magnetic fields that expands out into space from the Sun's corona. During this bursting of bubble-shaped solar plasma, the charged particles are sent out at the speed of light. The ejected plasma is composed mainly of protons and electrons, as well as quantities of elements. This phenomenon usually causes disruption in satellites and magnetic storms on Earth. Coronal mass ejection is caused by magnetic reconnection, which is the rearrangement of magnetic field lines in the Sun.
