它的地下海洋所含的水可能比地球上所有海洋的总和还要多。

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

因此，并不能仅仅因为木卫二地下海洋缺乏阳光就排除其孕育生命的可能。

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洋。

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

因此，并不能仅仅因为木卫二地下海洋缺乏阳光就排除其孕育生命的可能。

We can detect subsurface oceans on far-off icy moons, maybe even detect tiny ripples in space due to relativistic gravity.

我们可以在遥远的冰冷卫星上探测到地下海洋，甚至可以探测到相对论引力在太空中产生的微小涟漪。

And given the surprising revelations about its  possible subsurface ocean, you can be sure that there will be a lot more research on the subject.

鉴于有关其可能的地下海洋的令人惊讶的启示，您可以确信将会有更多关于该主题的研究。

Given the diminutive size of its core, you  wouldn't expect it to generate a lot of heat, so the evidence for a subsurface ocean  took a lot of people by surprise.

考虑到其核心的尺寸很小，你不会指望它会产生大量的热量，因此地下海洋的证据让很多人感到惊讶。

Then there's Titan, Saturn's largest moon, with its thick atmosphere and lakes of methane; and Europa, a moon of Jupiter, which may harbor a subsurface ocean, and with it, the potential for life.

然后是土星最大的卫星泰坦，它有厚厚的大气层和甲烷湖。木星的卫星木卫二可能蕴藏着地下海洋，并蕴藏着生命的潜力。
