Above the methane clouds and rain lies two hundred kilometers worth of globe-enveloping red smog, making the Titan nights starless and the days eerie dark, where high noon is as dim as deep Earth twilight. Over eons, smog particles have drifted downwards, growing as they fell, to coat the surface in a blanket of organic matter. On high, steep slopes, methane rains have washed away this sludge, revealing the bright bedrock of ice. Could Xanadu, the brightest feature on Titan, be a high, methane-washed, mountain range of ice?
Occasional bolts of lightning momentarily brighten the gloomy landscape
, and wind-blown waves lap the shores of hydrocarbon lakes and seas dotting the scene.
This is a rich and complex environment, where oddly familiar terrain is carved by odd and unfamiliar substances ... a fascinating, virgin world whose only rival may be the Earth itself, with sights still unseen by human eyes.
