    Saturn’s moon Mimas is known for its uncanny resemblance to the dreaded Death Star in the original "Star Wars" movie. But it has another intriguing distinction as well, according to researchers - a subsurface ocean hidden under its icy and crater-scarred outer shell.

    土星卫星「弥玛斯」因与初始「星际大战」电影中令人闻之色变的「死星」奇异地相似而闻名。但根据研究员说法,弥玛斯有另一个令人感兴趣的特点,那就是隐藏在其冰层和满目疮夷表壳之下的海洋。

    Mimas becomes the smallest of five moons in our solar system with compelling evidence of subsurface oceans, alongside Saturn’s Enceladus and Titan, and Jupiter’s Europa and Ganymede.

    弥玛斯成为太阳系中五个具有地下海洋有力证据卫星中最小的一个。其他为土星的恩克拉多斯和泰坦,木星的欧罗巴和盖尼米德。

    Mimas is the seventh-largest moon of Saturn, which all told has well over 100 moons ranging from Titan - larger than the planet Mercury - to some only the size of a city block.

    弥玛斯是土星第七大卫星。土星卫星数目超过100个,尺寸从比水星更大的泰坦,到部分仅有一个城市街区的大小。

    The liquid water inside Mimas represents more than half of this moon’s total volume, though it amounts to just 1.2-1.4% the amount in Earth’s oceans. The fact that the water is in contact with the rocky core of Mimas may facilitate the type of complex chemistry that could pave the way for life, they added.

    弥玛斯内部的液态水相当于其总体积的一半以上,不过这仅是地球海洋比例的1.2至1.4%。科学家补充说,水与弥玛斯的岩石核心交互作用之下,或许会催生复杂的化学反应型态,为生命铺平道路。
