The sun-orbiting SOHO spacecraft captured this snapshot of the development of a coronal mass ejection (CME), an explosive sun storm. It shows erupting filaments lifting off the active solar surface and blasting enormous bubbles of magnetic plasma into space. CMEs occur anywhere from once a week to two or more times a day, and they can profoundly influence space weather.
