Saturn’s moon Titan is one of the most intriguing bodies in our
solar system. Its dense atmosphere and lakes of liquid methane
make it both beautiful and bizarre, as well as a tantalizing
target for those seeking extraterrestrial life. To me, though,
the most amazing thing (so far) has been the revelation that is
Titan’s meteorology. There’s something extraordinary about
imagining liquid methane falling as rain on another world—it’s
so similar to our experience, yet so very different. Earth has a
familiar hydrologic cycle; Titan has an alien methane cycle.  In
a letter published in Nature, researchers describe a model that
successfully simulates some key aspects of Titan’s weather. The
model offers possible explanations for some of the moon's quirky
features that have long been puzzling.  Previous attempts to
