Obrazem: Sluneční erupce na snímcích NASA

A coronal hole, the dark spot beginning just below the sun's center and extending to the right, is shown opening up in this image by NASA satellite STEREO. The NASA satellite SABER has detected a periodic "breathing" response in the Earth's upper atmosphere in response to never before observed regular coronal hole openings on the sun's surface. The coronal holes release high-powered solar winds that disturb the upper atmosphere of Earth and force it to emit energy to maintain the earth's radiation budget. Image credit: NASA/STEREO
