PD 8 - Image created by NASA.
Taken by Hinode's Solar Optical Telescope on Jan. 12, 2007, this image of the sun reveals the filamentary nature
of the plasma connecting regions of different magnetic polarity. Hinode captures these very dynamic pictures of the chromosphere.
The chromosphere is a thin "layer" of solar atmosphere "sandwiched" between the visible surface, photosphere, and corona.
