  • Title: Evidence for the exposure of water ice on Titan's surface.
    Author: Griffith CA, Owen T, Geballe TR, Rayner J, Rannou P.
    Journal: Science; 2003 Apr 25; 300(5619):628-30. PubMed ID: 12714742.
    Abstract:
    The smoggy stratosphere of Saturn's largest moon, Titan, veils its surface from view, except at narrow wavelengths centered at 0.83, 0.94, 1.07, 1.28, 1.58, 2.0, 2.9, and 5.0 micrometers. We derived a spectrum of Titan's surface within these "windows" and detected features characteristic of water ice. Therefore, despite the hundreds of meters of organic liquids and solids hypothesized to exist on Titan's surface, its icy bedrock lies extensively exposed.
