Flight Over Titan's Lakes
This computer animation gives us a glimpse of one of the Solar System's largest natural satellites -
Titan, the biggest moon of Saturn.
Titan, which is 50% bigger than our own
Moon, was the subject of the Huygens probe in 2005, glimpsed at the end of this clip. It is the only
known moon with a substantial atmosphere (of molecular nitrogen, as on Earth), but it is far, far
colder than even our Antarctica, at -180 degrees Celsius. Its surface is primarily rock and water
ice - and it is the only world aside from Earth on which stable bodies of liquid have been seen. But
these are not lakes of water, which freezes as hard as rock on Titan. No, Titan's seas are made of
methane.
