Ejections

Just as weather varies on Earth, occasionally bringing thunderstorms and gusty winds, the ever-changing Sun sometimes hurls massive clouds of solar material and magnetic fields into space, called coronal mass ejections, or CMEs.

These outbursts from the sun, which eject energy in the form of magnetic fields and billions of tons of plasma gas known as "coronal mass ejections," are unpredictable and difficult to anticipate.

The Sun’s magnetic field changes over a repeating 11-year cycle that causes an ebb and flow of solar activity such as sunspots, solar flares and coronal mass ejections.
