A '''coronal mass ejection''' (often abbreviated to CME) is a large outburst of [[plasma]] from the solar [[corona]], the outermost layer of the [[Sun]].<ref name=britannica>{{cite web|url=https://www.britannica.com/topic/coronal-mass-ejection|title=Coronal mass ejection|accessdate=2019-01-04}}</ref> These travel radially outwards from the Sun at [[speed]]s ranging from 250-3,000 km/s.<ref name=noaa>{{cite web|url=https://www.swpc.noaa.gov/phenomena/coronal-mass-ejections|title=CORONAL MASS EJECTIONS|accessdate=2019-01-5}}</ref> Coronal mass ejections can contain billions of tons of material and also possess an internal [[magnetic field]]. CMEs can be responsible for [[geomagnetic storm]]s on [[Earth]], which disturb the Earth's own magnetic field and may damage electronics.
