Shadows on Kepler-16b
Kepler-16b has an unusual feature not mentioned in the article. Possibly the first visitors there can write up a scientific paper describing why the shadows appear to be the wrong colors.
I'm not really a shadow-scientist, but I would expect shadow from the white sun, since it is illuminated by the red sun, to have the more reddish color. The shadow from the red sun should be neutral in color, since it is illuminated by a white sun.
