For 10 points, name this phenomenon, a stream of plasma emitted from the Sun, which maintains its heliosphere.
This phenomenon can create corotating interaction regions, which are bounded by a forward shock and a reverse shock. This phenomenon may have taken away as much as a third of Mars' atmosphere by ripping away gas caught in bubbles of magnetic field. This phenomenon can be either "fast" or "slow" based on whether its source is open or closed, and it is discharged by coronal mass ejections. The northern lights, also known as Aurora Borealis, are seen close to the pole because of this phenomenon.
