Term: Corona
Definition:

The sun's dynamic atmosphere is called the corona. It is filled with electrically charged particles, whose movements are governed by the tangle of magnetic fields surrounding the sun. While the sun's surface is 6000K, the corona can reach up to millions of degrees, sparking questions from researchers on mechanisms heat the atmosphere so dramatically. Solar flares and coronal mass ejections originate in the corona.
