Hinode's Extreme ultraviolet Imaging Spectrometer (EIS) captured this mosaic set of images during the miminum and maximum phases of the solar cycle. EIS uses a slit to disperse
the light and observe the sun at very specific temperatures. Each full scan takes a few days to complete. This false-colored image is composed of three different temperatures, increasing
from blue to red. During solar maximum, the atmosphere of the sun becomes full of very hot material above the active regions. EIS is designed to show us where that material comes from
and where it is going.
