Coronal Mass Ejection Accompanies X-class Flare


Coronal Mass Ejection

A giant cloud of solar particles, called a coronal mass ejection, explodes off the sun on Jan. 7, 2014

The Jan. 7, 2014, X-class flare was also associated with a coronal mass ejection, or CME, another solar phenomenon that can send billions of tons of particles into space that can reach Earth one to three days later. These particles cannot travel through the atmosphere to harm humans on Earth, but they can affect electronic systems in satellites and on the ground.

The European Space Agency and NASA's Solar and Heliospheric Observatory, or SOHO, captured an image of the giant particle cloud as it burst away from the sun.
