San Francisco Chronicle: When Earth was very young a few billion years ago, a thick smoggy haze shrouded the planet -- a haze much like the one that kept astronomers from seeing the surface of Saturn’s moon Titan until last year, when the Huygens space probe parachuted through the moon’s atmosphere onto its tarry landscape.
The finding that the Saturnian moon may host layers of icy slush instead of a global ocean could change how planetary scientists think about other icy moons as well.
