Hinode captures this very dynamic movie of the chromosphere. The chromosphere is a thin "layer" of solar atmosphere "sandwiched" between visible surface, photosphere, and corona. The chromosphere is the source of ultraviolet radiation. Before these images, scientists thought the chromosphere was a motionless "layer." Hinode shows that this description is obsolete. The observatory reveals a chromosphere that appears as constantly moving field lines like grassland with tall grass swaying under the wind.
