Winter is coming

For the south pole of Titan.

A seven-year autumn has begun on the south pole of Saturn's largest moon, scientists believe. An ice cloud made from an unknown material taking shape over Titan’s south pole has led experts to deem that an important pattern of global air circulation on the moon has reversed direction.

The same type of cloud has been hanging over Titan's north pole, but it is now fading and spring has arrived there, according to observations made by an infrared spectrometer on NASA's Cassini craft.
