Don: Nice telescope, Yael, what are you looking at?
唐：不错的望远镜，雅艾尔，你在看什么？
Yale: Bacteria.
雅艾尔：细菌-kC(lz(9wmtp7(boI+5。
Don: In space?
唐：在太空吗？
Yale: Not that far out, Don. Scientists recently collected three brand new species of bacteria from the Stratosphere. When I heard about it, I couldn't believe it. Researchers have been using balloon lifted cryosamplers to collect bacteria and fungi from the stratosphere for years.

Don: I didn't think that anything can live that high in the amosphere.
唐：我不认为在那么高的大气中会有生命存在Q)=ekW@e(G1b。
Yale: Neither did I. The stratosphere extends from ten to thirty miles above the surface. That's above the clouds where temperatures can get as cold as minus 76 degrees Fahrenheit, and there's lots of ultra violet radiation.
雅艾尔：我以前也是36,ezYgvQc3*EJiX。平流层位于距地表10英里至30英里的高度eNePel[H7O6,zbtyD5。那里在云端之上，温度可低至零下76摄氏度，并且有大量的紫外线辐射IgWlhX2qDBR~R[ss8w.。
Don: So How do they think bacteria got up there?
唐：那他们认为细菌是如何到达那里的？
Yale: Some scientists think they ride up on particles ejected from volcanoes. Others think bacteria might be sucked through updrafts caused by a special kind of lightning that travels upwards from cloud tops. Forest fires can also cause thunderstorms that toss immense plumes of smoke into the stratosphere. Bacteria could ride on the soot.
雅艾尔：有些科学家认为细菌是由火山喷射出的粒子带上去的R7=Br*eci&U[8K%I|。还有人则认为，细菌也许是卷入了一种自云层顶端向上运行的特殊闪电造成的上升气流+1[_,qd6R(xykfN。森林火灾会引起雷暴，将大量浓烟掷入平流层q@JRjm[8ki7a(AD。细菌可能会驾尘而上NK,te^p-9f。
Don: And they are the same kind Of bacteria that live here on the surface?
唐：那么它们与生活在地表的细菌是同一种类吗？
Yale: Some are known species. They have found rod-shaped Bacillus that are very common here as well as Staphylococcus species related to disease causing bacteria. Others are completely new, including two new Bacillus species. There's also a third group of bacteria found in clumps that can't be cultured in normal bacterial nutrients. So far, they are a puzzle.

Don: That's really out of this world, Yael. But you really are trying to see bacteria with your telescope, are you?
唐：那真是不可思议，雅艾尔t|H9%;E_v,)zOue92。但你真的在用望眼镜观察细菌，是吗？
Yale: No, Don. They are away too small. I'm just out enjoying the stars.
雅艾尔：不，唐]@rTphshS&o,y3M。它们太远，并且太小dT8R[9z[sJQn28W*A。我只是在观赏星星njC|50n99*。
