Planetary science:  Shades of Titan

Louise Prockter1

Instruments aboard the Cassini spacecraft can 'see' through the dense atmosphere of Titan, Saturn's largest moon. Returned images hint at the existence of features such as ridges and valleys, and perhaps an icy volcano.

Wreathed in clouds and haze, Titan has long been the focus of Earth-based telescopes, and their probings have yielded tantalizing clues about the nature of the moon's surface. The main obstacle to studying Titan's surface is its atmosphere of nitrogen and methane — peeking through the dense fog is a tough task.
