lakes on pluto

Sorry I don't have the image reference but the high res image of the heart region show what looks very much like lakes in the troughs. Probably liquid nitrogen or some hydrocarbon. Maybe both. The action from the nasa post of the image says some of the troughs are filled with some kind of "dark material". ha typical nasa scientist evasiveness. They are lakes!!!

Anyone else notice that? Fantastic!!!

This is the image i was refering to
