Coronal Mass Ejection
Here we see a long filament of solar material erupting out into space at over 900 miles per second. Called a Coronal Mass Ejection, the eruption is a massive burst of solar wind and magnetic fields rising above the Sun's atmosphere and released into space. These eruptions can occur as often as three times per day, or as seldom as one every five days. The ejected material is plasma consisting mostly of electrons and protons.
