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.

Emily Mason, a heliophysicist at San Diego-based research firm Predictive Science, and her colleagues observed coronal loops ...

Coronal mass ejections, or CMEs, are dramatic outbursts during which the Sun blasts charged particles into space at incredibly high speeds. These outbursts occur more often when the star is in one ...

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