Description:
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.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Griffith, Caitlin A -- Owen, Tobias -- Geballe, Thomas R -- Rayner, John -- Rannou, Pascal -- New York, N.Y. -- Science. 2003 Apr 25;300(5619):628-30.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Planetary Sciences, University of Arizona, 1629 East University Boulevard, Tucson, AZ 85721-0092, USA. griffith@lpl.arizona.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12714742" target="_blank"〉PubMed〈/a〉
