A 3D Solar Wave


Truth feeder
When a coronal mass ejection (CME) erupts from the Sun, movies in extreme ultraviolet light often show enormous waves, spreading over a large area on the solar surface, just as tsunamis travel far from the original seismic event. Now STEREO data have been used to show that these waves are the footprints of giant domes that spread upward into the corona as well as outward across the surface.
