地球上的深海热泉是生命的绝佳住所。那么土卫二呢?
So hydrothermal vents are a fabulous abode for life here on Earth. So what about Enceladus?
土卫二比飞行器更接近土星,它距离卡西尼的摄像机只有60000千米。
Closer to the spacecraft than Saturn, Enceladus is a mere 60, 000 kilometers from Cassini's camera.
土卫二的喷发泉有可能将存在于其内部地下海洋的钠元素喷发至土星的E环中。
Enceladus' geysers could have delivered sodium from its underground ocean and into Saturn's E ring
从土卫二号北半球的这个角度来看,大型坑洞以及坑洞地带是非常罕见的。
Craters and cratered terrains are rare in this view of the southern region of the moon's Saturn-facing hemisphere.
这种从下而来的加热使土卫二和木卫二都能在其冰凉寒冷的表面下蕴藏海洋。
Such heating from below allows both Enceladus and Europa to harbour oceans under their cold, icy surfaces.

土星的另一颗卫星——土卫二是喷冰的喷泉所在之地,也会得到详细的的探测。
Another of Saturn's moons, Enceladus, which is home to geysers that spew ice, will also be explored in detail.
正是这样的结果,让我们相信土卫二是太阳系中我们找到的最令人感到激动的地点。
Results like this make Enceladus one of the most exciting places we've found in the solar system.
据科学家推测,土卫二冰冷的表面99%被水冰覆盖,地表之下存在液态水的几率也很大。
The surface of the icy moon is thought to be about 99 percent water ice, with a good chance of liquid water beneath.
可以在图片左边看到土卫二Enceladus,它被蓝色包裹,拖着冰块组成的羽翼绕着土星飞行。
The moon Enceladus is also captured on the left, swathed in blue and trailing its plume of water ice particles through Saturn's E ring.
卡西尼号土星探测器最近发现了可能能够证明在冰冷的土星卫星土卫二的地下存在着地下海洋的确切的证据。
The Cassini spacecraft has found what may be the strongest evidence yet that Saturn's tiny moon Enceladus has an ocean beneath its icy surface.
“这些液体水深藏在土卫二的地壳内部中的岩石中,并逐渐通过过滤作用从岩石内部获得钠元素。”Lunine说。
"A liquid water layer or pocket in contact with the rock, which is deep below Enceladus' surface, will acquire sodium from the rock - essentially leaching the rock," he says.
据证实,土星的一颗小卫星,土卫二(上图所示)以及木卫二有充足的水:土卫二的水量可能有苏必利尔湖那么多。
And it hasturned out that Enceladus, a small moon of Saturn (illustrated above) and Europa have it in abundance: Enceladus may have as much as Lake Superior.

现在对温度的测量还不尽准确,越热的表面温度预示着越热的内部温度,这增加了土卫二内蕴含着大量液态水的可能性。
Although the temperature estimate is not yet definitive, the hotter the surface temperature makes for a hotter interior, strengthening the chances of pools of liquid water inside the moon.
土卫六的大气层使它成为太阳系中和地球最为相像的星体之一,至于土卫二,科学家则希望能更多的了解它的构造活动。
Titan's atmosphere makes it one of the most Earth-like bodies in our solar system, and scientists are hoping to learn more about Encaledus' tectonic activity.
该探测器在很短的检测时间内就发现了钠元素的存在,并确认了这些从土卫二中喷发出的物质含有支持生命产生的复杂有机分子。
The instrument, which looked for sodium only during short intervals of the flyby, did identify an array of organic compounds in the plumes that could support life.
科学家们认为土卫二冰火山的活跃时间只占其寿命时间的1%到20%,幸运的是,卡西尼号飞越土卫二的时候正好赶上了喷发期。
Scientists believe the cryovolcanism on Enceladus has only been active during 1 to 20 percent of its existence. We’re glad Cassini caught it in an eruptive phase.
这些裂缝被称为虎纹,天文学家最早在2005年从卡西尼的照片上发现它们,为活跃的土卫二上存在液态水提供了有力的证据。
The fissures have been dubbed tiger stripes. First discovered in Cassini images from 2005, the plumes are strong evidence that liquid water exists near the surface of surprisingly active Enceladus.
最早是在2005年卡西尼所拍摄的照片中发现的,这些缕缕水气是非常有力的证据,说明在这颗惊人地活跃的土卫二的表面附近存在液态水。
First discovered in Cassini images from 2005, the plumes are strong evidence that liquid water exists near the surface of surprisingly active Enceladus.
