Enceladus continues to exhale water ice into saturn orbit , keeping the e ring topped off with tiny particles 土卫二继续喷发冰粒到土星轨道中，使处于外围的e环充满了微小的微粒。

The find suggests that the moon ' s core once reached temperatures around 1 , 070 degrees fahrenheit ( 577 degrees celsius ) ? hot enough to convert enceladus ' s internal stores of ammonia into nitrogen 这个发现还指出，卫星内核的温度曾达到过华氏1070度左右（摄氏577度） ? ?这个温度足够内部贮藏的氨气分解出氮。

Enceladus , a moon of saturn , stunned scientists two years ago when nasa ' s cassini orbiter discovered geyser - like jets of water vapor shooting into space from its south pole 恩克拉多斯（土卫二）是土星的一个卫星。两年前卡西尼号人造卫星发现一股喷泉状的水蒸气从它的南极射向外太空，令美国宇航行局感到非常震惊。

For example , saturn ' s e ring reaches across a broad region that encompasses the satellites mimas , tethys , dione and rhea , peaking in brightness at the orbit of the smooth , icy moon enceladus 例如，土星的e环所跨过的一大片区域中，包含了土卫一、土卫三、土卫四与土卫五等卫星，亮度的最高峰就处于平滑冰冷的土卫二之轨道上。

During a rare observation last weekend , cassini ' s cameras revealed a new ring at saturn and other spectacular sights , including wispy fingers of icy material stretching out tens of thousands of kilometers from enceladus and even an image of distant planet earth 在上周少有的观测中，卡西尼的照相机显示出土星的一个新环和其他一些壮观景象，包括从土卫二伸展出的数万千米细指状冰物质以及回望地球的一张照片。
