A new study has provided precise atomic data that shed light on the impact of charged ions from coronal mass ejections (CMEs) ...

This activity is connected to a fast-moving coronal mass ejection, or CME, that left the Sun on Friday. According to SWPC’s ...

Sometimes, a solar flare and a coronal mass ejection (or CME) happen at the same time. A CME is an eruption of plasma and ...

These events are called coronal mass ejections, or CMEs. When two of these ejections collide, they can generate powerful geomagnetic storms that can lead to beautiful auroras but may disrupt ...

This composite image shows a coronal mass ejection, a type of space weather linked to solar energetic particles, as seen from two space-based solar observatories and one ground-based instrument.

Solar flares are bursts of radiation from the sun’s surface, sometimes followed by a bubble of magnetized plasma particles called a coronal mass ejection (CME). If they happen to spray out in ...
