Composite Image of the Sun
The four images of the Sun (Dec. 7, 2011), taken by NASA at almost the same time, showing various wavelengths in various temperatures and layers of the Sun. The first section shows the photosphere that displays the various sunspots on the “surface" of the Sun. Then it transitions into the region between the chromosphere and the corona where, in extreme UV light, the active regions appear lighter. Next is a composite of three different wavelengths showing temperatures up to 2 million degrees C. The last image is an overlay of a science-based estimation of the complex magnetic field lines extending from and connecting the active regions before going back to the sunspot image. Who says the Sun is boring?
