re: IAPETUS' eye
Reminding of Clarke's 2001, Iapetus looks like it has an eye...
But a dark one, on the right side
Those familiar with the Moon, know about crater Proclus forming the area of Palus Somni, an ejecta area coming from what caused Proclus crater!
Could what has formed the big crater on Iapetus, also has spread dark material on the surface?
