It is named after Giovanni Cassini, the discoverer of Iapetus; 'Regio' is a term used in planetary geology for a large area that is strongly differentiated in colour or albedo from its surroundings. The brighter half of Iapetus is called the Roncevaux Terra. The nature of the material that caused the extensive discoloration of Cassini Regio is not known, but it appears to be quite thin. It may be the result of cryo-vulcanism, a spattering of material from outer moons, or residue left by the sublimation of brighter ice. In December 2004 an image taken by the NASA ''Cassini'' probe revealed that a long ridge of high mountains runs down the centre of Cassini Regio, almost perfectly following Iapetus's equator. The origin of this extremely unusual feature is as yet unknown. ''Cassini'' completed a flyby of Iapetus in September 2007, and the images it has transmitted are helping to clarify the nature of Cassini Regio. For more details, see the main article on Iapetus. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Cassini Regio」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
