Coronal mass ejections (CMEs) are colossal expulsions of plasma and magnetic field from the sun's corona. Explore CMEs in more detail here in our guide.

The coronal mass ejection video was captured over one hour and 15 minutes, Ayoub shared in his Reddit post. He then sped up the video to around five seconds so that viewers could watch the action ...

The sun launched this coronal mass ejection at some 900 miles/second (nearly 1,500 km/s) on Aug. 31, 2012. The Earth is not this close to the sun; the image is for scale purposes only.

Coronal mass ejections (CMEs) are quite possibly the most terrifying storms in the solar system (yes, even more horrifying than Jupiter's Great Red Spot). Imagine an explosion that sends 100 ...

A coronal mass ejection (CME) being launched by a solar flare (highlighted) on July 15. The CME later cannibalized another CME that launched earlier on July 14 and is now heading straight for Earth.

NASA has captured the moment a "cannibal" coronal mass ejection (CME) was launched from the surface of the sun on August 15 in incredible footage. Sunspot region 3078, which currently contains 13 ...

A coronal mass ejection (CME) is a huge expulsion of plasma from the sun’s corona, which travels across the solar system as solar wind. These solar winds travel all the way to Earth and can ...

A coronal mass ejection (CME) followed the flare but is not expected to hit Earth. More solar activity is anticipated from sunspot AR4046 and AR4048, with a 15% ch ...
