coronal mass ejections

The coronal mass ejection traveled between 1,800 and 2,200 miles per second.

The flares unleashed two coronal mass ejections that hit Earth on June 16.

The solar flare kicked up a massive explosion of super-heated magnetic plasma.

The trigger for explosive solar flares may be found.

The sun unleashed two major X-class solar flares in about one hour on March 6, 2012.

Four of the eruptions came within a 24-hour period.

The sun's violent activity expands Earth's atmosphere, which increases the rate that space junk falls from orbit.

An X-class flare, the most powerful type of solar storm, erupted from the sun today.

Sunspots on the sun's surface are responsible for some recent major solar storms.

The six residents of the International Space Station are safe from a massive solar storm erupting on the sun.
