I'm with a half dozen scientists who are hunting peculiar landforms called pingos -- or, more specifically, the microbes that live within them.

我跟着一群科学家去找一种名叫冰丘的特殊地形，或者更精确地说，找生存在其中的生物。

The microbes populating the pingos could offer a glimpse at how alien life might survive on other worlds in the solar system -- icy moons with global seas tucked beneath frozen rinds.

生活在冰丘里的生物，能让我们稍在太阳系的其他世界--也就在冰壳底下藏着全球性海洋的那些冰冷卫星上--外星生命可能的生存方式。

" That's because, in winter, life inside the pingo doesn't rely at all on solar energy -- it's only using chemical energy, " says microbiologist Dimitri Kalenitchenko of Norway's University of Tromso, who is leading the project.

“因为在冬天，冰丘里的生命完全不依靠太阳能，只利用化学能”，领导这一项目的挪威特罗姆瑟大学生物学家迪米崔·卡列尼琴科如说。
