Scientists are particularly interested in Saturn's moon Titan because it's one of the few known moons with its own dense atmosphere. Titan's atmosphere is also thought to be very similar to what Earth's atmosphere was a long time ago. By learning about Titan, we'll learn about our own planet.

Rainbows on Titan

When the European Space Agency's Huygens probe visited Saturn's moon Titan in January, the probe parachuted through humid clouds, photographed river channels, and landed in mud. Titan's "water" is liquid methane, better known on Earth as natural gas. Regular Earth-water would be frozen solid on Titan where the surface temperature is 290 degrees F below zero. Methane, on the other hand, is a flowing liquid.

Titan is of particular interest to astrobiologists because it is the only known moon in the Solar System with a thick atmosphere. Studying the organic chemistry of Titan's atmosphere, which could resemble that of early Earth, may help scientists understand the origin of life on our planet. Understanding how life emerges from cosmic and planetary precursors is a primary goal of astrobiology.
