coronal mass ejection

A recent X-class flare, which was split into two simultaneous explosions, launched a coronal mass ejection that smashed into Earth, triggering the most powerful disruption to our planet's magnetic field for more than six years.

A gigantic plasma eruption from the sun's hidden far side recently launched a sizable coronal mass ejection that slammed into Mercury, potentially triggering invisible X-ray auroras around the planet's rocky surface.

A recent solar flare unleashed a massive plasma plume from the sun's south pole, where these stellar eruptions rarely happen. The unusual phenomenon is a sign of the impending solar maximum.

A photographer recently snapped an incredibly detailed photo of gigantic, ghostly plasma loops towering above the sun's fiery surface after a powerful solar flare exploded from the sun.

In the final hours of Dec. 31, 2023, the sun launched its most powerful solar flare in 6 years. On Jan. 2, radiation from the blast may bring auroras to Earth's skies.

On Dec. 14, a 2.8 magnitude X-class flare exploded from the sun, triggering radio blackouts on Earth and unleashing a CME that could also hit our planet in the next few days. It is the most powerful solar flare in more than six years.

A recent solar explosion that almost reached "X-class" status has hurled a massive coronal mass ejection toward Earth, which will likely hit our planet and trigger a geomagnetic storm on Dec. 1.

A striking new image shows bright orange auroras dancing in the night sky above Canada. But auroras should never be this color, so what's going on?

High radiocarbon levels in the rings of subfossil tree stumps suggest that an incomprehensibly powerful solar storm, known as a "Miyake event," smashed into our planet more than 14 millennia ago.

After surviving its closest approach to the sun, Comet Nishimura was buffeted by a possible coronal mass ejection that briefly blew its tail away. The rare event was captured by a NASA spacecraft.
