This page describes an image Enceladus
Image caption:
On 9 Oct. 2008, just after coming within 25 kilometers (15.6 miles) of the surface of Enceladus, NASA's Cassini probe captured this stunning mosaic of Saturn's 500 km large ice-moon. Craters and cratered terrains are rare in this view of the southern region of the moon's Saturn-facing hemisphere. Instead, the surface is replete with fractures, folds, and ridges — all hallmarks of remarkable tectonic activity for a relatively small world. In this enhanced-color view, regions that appear blue-green are thought to be coated with larger grains than those that appear white or gray. Similar to Europa, Enceladus has a subsurface ocean of liquid water spanning the entire moon.

Image caption: Le 9 octobre 2008, juste après s'être approchée à 25 km de la surface d'Encelade, la sonde Cassini de la NASA a capturé cette étonnante mosaïque de la lune glacée de Saturne, d'une taille de 500 km. Les cratères et les terrains cratérisés sont rares dans cette vue de la région sud de l'hémisphère de la lune faisant face à Saturne. Au contraire, la surface est remplie de fractures, de plis et de crêtes, autant de signes d'une activité tectonique remarquable pour un monde relativement petit. Dans cette vue en fausses couleurs, les régions qui apparaissent en bleu-vert sont supposées être recouvertes de grains plus gros que ceux qui apparaissent en blanc ou en gris. À l'instar d'Europe, Encelade possède un océan souterrain d'eau liquide qui s'étend sur l'ensemble de la lune.

Image caption: Il 9 ottobre 2008, poco dopo essersi avvicinata fino a 25 chilometri dalla superficie di Encelado, la sonda Cassini della NASA ha catturato questo straordinario mosaico della luna ghiacciata di Saturno, grande 500 chilometri. Crateri e terreni craterizzati sono rari in questa visuale della regione meridionale dell'emisfero della luna rivolto verso Saturno. La superficie è invece ricca di fratture, pieghe e creste, tutti segni di una notevole attività tettonica per un mondo relativamente piccolo. In questa immagine a colori potenziati, si ritiene che le regioni che appaiono blu-verdi siano ricoperte da rocce più grandi rispetto a quelle che appaiono bianche o grigie. Come Europa, anche Encelado ha un oceano sotterraneo di acqua liquida che si estende su tutta la luna.

Image caption: 2008年10月9日，美国国家航空航天局的卡西尼号探测器在从距离表面25千米（15.6英里）的位置飞掠土卫二之后，拍摄到了土星这颗500千米大的冰质卫星令人惊叹的图像。在这颗卫星面向土星的半球上，南部区域的陨击坑和火山口地形非常罕见。相反，月球表面充斥着裂缝、褶皱和山脊——对于一颗相对较小的星球来说，这些都是显著构造活动的标志。在这个增强彩色视图中，与那些呈现白色或灰色的区域相比，呈现蓝绿色的区域被认为覆盖着更大的颗粒。与木卫二类似，土卫二也有一个覆盖了整颗星球的液态水海洋。
部分被照亮的土卫二的假彩色图像。白色的表面上有许多方向不规则的直线和曲线裂缝。
