The sun's activity has been ramping as it approaches its 11 year peak
A plume of"dark plasma" hurled from the sun will be engulfed to form a"cannibal" coronal mass ejection which will sideswipe the Earth on Thursday , causing a strong G3 geomagnetic storm.
Sunspots are areas on the sun's surface where powerful magnetic fields, created by the flow of electrical charges, knot into kinks before suddenly snapping. The resulting release of energy launches bursts of radiation called solar flares, or plumes of solar material called coronal mass ejections.
Geomagnetic storms occur when planets with strong magnetic fields, like our own, absorb the high speed barrage of solar debris from CMEs. During these storms, Earth's magnetic field gets compressed slightly by waves of highly energetic particles. These particles trickle down magnetic-field lines near the poles and agitate molecules in the atmosphere, releasing energy in the form of light to create colorful auroras, similar to the ones that make up the Northern Lights.
More extreme geomagnetic storms can disrupt our planet's magnetic field powerfully enough to send satellites tumbling to Earth, Live Science previously reported, and scientists have warned that extreme geomagnetic storms could even cripple the internet.
