Alien thunder

From Astrobiology Magazine:

The sound of alien thunder, the patter of methane rain and the crunch (or splash) of a landing, all might be heard as Huygens descends to the surface of Titan on 14 January 2005.

What's more, they will be recorded by a microphone on the probe and relayed back so that everyone on Earth can hear the sounds of Titan.
