So the lack of light in Europa's subsurface ocean doesn't automatically rule out life forming.

因，并不能仅仅因为木卫二地下海缺乏阳光就排除其孕育生命的可能。

There had to be liquid water the crucial ingredient for life on Europa.

木卫二存在生命的关键元素，也就是水。

Scientists, myself included, have long been interested in the possibility of life on Europa.

包括我在内的科学家们长期以来一直对木卫二存在生命的可能性感兴趣。

Too distant, like the Jupiter's frozen moon Europa?

还是太远了，就像木星冰冻的卫星木卫二一样？

And it's already been discovered that just beneath Europa's icy surface there's an ocean.

人们已发现，在木卫二的冰面下有一片海。

The findings support other evidence of plumes from Europa, whose ocean may contain two times as much water as all of Earth’s oceans. In 2012, NASA’s Hubble Space Telescope collected evidence of ultraviolet radiation which suggests a plume.

这些发现支持了其他证明木卫二有羽状水汽的证据，木卫二的海水量可能是地球所有海水量的两倍。2012年，美国宇航哈勃太空望远镜收集到了紫外线辐射证据，暗示存在羽状水汽。

The ESA took the opportunity to do a test run of Juice's instruments, which it will use to look for molecular signatures of habitability on the moons Europa, Ganymede and Callisto.

欧洲航天机会对 Juice 的仪器进行了测试，这些仪器将用于寻找木卫二、木卫三和木卫四适宜居住的分子特征。

So this one is going to make at least 50 flybys of Europa, sometimes going as low as 16 miles or 25 kilometers above the surface — so that's close.

因这艘飞船将至少飞越木卫二 50 次，有时会飞到距离表面 16 英里或 25 公里的位置——这个高度很低了。

The amount of water that may be locked up on Europa is staggering; easily more than all the water in all the oceans on Earth!

木卫二储存的液态水是恒定的；其总量很容易就超过地球各大海之和。

In 1610, for example, Galileo used the first telescope to discover Jupiter's moons Io, Callisto, Europa, and Ganymede — now known as the Galilean Moons.

例如，1610 年，伽利略用第一台望远镜发现了木星的卫星木卫一、木卫四、木卫二和木卫三，这些卫星现在被称为伽利略卫星。

Characterizing Europa's frozen shell and the compounds on its surface is one of the highest priorities for both the Europa Clipper and JUICE missions.

木卫二独特的冰冻外壳及其表面的化合物是木卫二快艇号和JUICE任务的最高优先事项之一。

The question of life on Europa is probably the big meal unknown, because that would change our view of the Universe, basically.

木卫二的生命可能是未知的大餐，主要是它可能会改变我们对宇宙的认识。

Recently, close up pictures of Jupiter's moon Europa shows signs of water beneath its icy surface.

最近，木星的卫星木卫二的特写照片显示，在其冰冷的表面下有水的迹象。

Juice will investigate three of the so-called Galilean moons-Callisto, Europa and Ganymede, all of which are thought to have subsurface oceans.

“果汁”探测器将调查三颗所谓的伽利略卫星——木卫四、木卫二和木卫三，这三颗卫星都被认为拥有地下海。

Jupiter's moons include the largest in the solar system, Ganymede, an ocean moon called Europa and a volcanic moon named lo.

木星的卫星包括太阳系中最大的木卫三，一颗名为木卫二的海卫星和一颗名为lo的火山卫星。

The four largest moons, Io, Europa, Ganymede, and Callisto, are large enough to be seen from Earth with a telescope.

从地球就可以用望远镜看到最大的四颗卫星，木卫一，木卫二，木卫三，木卫四。

In other words, Daswani said, the makeup of Europa's ocean may have been very similar to oceans on Earth.

达斯瓦尼表示，换句话说，木卫二海的构成可能与地球海的构成非常相似。

Space probes have provided evidence that Europa has a large ocean under its surface.

航天探测器探测数据证明木卫二表层之下蕴藏着一片汪大海。

Astronomer, Professor Melissa McClure, worked with the Nasa scientists who found ice on Europa, one of Jupiter's moons.

天文学家梅丽莎·麦克卢尔教授与美国宇航的科学家们合作，他们在在木星的卫星之一——木卫二欧罗巴发现了冰。

Then there is Europa, the ice queen to Jupiter's king.

接着是欧罗巴(木卫二)，木星国王的冰王后。
