The blurring effects of Titan's aerosol are obvious in this image, where the orange moon peeks from behind two of Saturn's rings. Small, battered Epimetheus, another of Saturn's 62 moons, appears just above the rings.Every day is a bad-air day on Saturn's largest moon, Titan. Blanketed by haze far worse than any smog belched out in Los Angeles, Beijing or even Sherlock Holmes's London, the moon looks like a dirty orange ball. Described once as crude oil without the sulfur, the haze is made of tiny droplets of hydrocarbons with other, more noxious chemicals mixed in. Unlike Titan's brownish haze, the ice clouds have the pearly white appearance of freshly fallen snow.
