Space Mysteries　太空搜密

by Kevin Lustig

The universe is a big place. In all of that space, humans have discovered many things that both fascinate and mystify us. Tune in to the National Geographic Channel this month to learn about some intriguing Space Mysteries.

When bright objects with long tails flew through the skies over the ancient world, people were often terrified. Now when we see these impressive lights in the sky, we know they aren't omens of disaster, but comets. Of course, comets are more than just beautiful displays in the sky. The water they hold may someday be used to support human space exploration. NASA's Deep Impact project crashed a spacecraft into one of these balls of rock and ice to discover more about the secrets of Comets.

When we look up into the night sky, what we see is just a fraction of all of the bodies in space. It takes powerful telescopes to see much of what's out there. However, even the most powerful telescope can't see black holes. These are dark points in the universe where the gravity is so strong that even light can't escape. By simulating these mysterious objects on computers, scientists are learning about the many ways in which the universe relies on Black Holes.

There is a lot of debate about the existence of aliens. If they are real, the people at the Search for Extra-Terrestrial Intelligence (SETI) will probably know about it first. This group of scientists and amateur astronomers are searching the skies for evidence of alien life. To do it, they're using huge collections of satellite dishes and advanced computing power. Today, this technology continues mankind's decades-old search for Extra-Terrestrial Intelligence.

Think you know a lot about outer space? There may be more going on out there than you think. Let the National Geographic Channel show you some of the most incredible, unexpected parts of our universe in Space Mysteries.

中文翻译＆标准答案

宇宙浩瀚无涯，在这广大的空间中，人类已经发现许多既迷人又神秘的事物。请收看本月份的国家地理频道，一睹令人好奇的《太空搜密》系列节目。

在古代，当拖着长尾巴的发光体划过天际，常引起人们的恐慌。现在看到天空中出现这夺目的光体时，我们知道这是彗星飞过，而不是灾难发生的预兆。当然，彗星不只是空中炫丽的景观，它们夹带的水气也许有一天可以供应人类从事太空探险所需的水源补给。美国航天总署的 Deep Impact 计划发射了一艘宇宙飞船，去撞击一颗岩石和冰所组成的球体以发现更多关于《彗星》的秘密。

当我们仰望夜空，所窥见的不过是沧海一粟，需要高倍数望镜才能看得更多。然而，就算是透过最高倍数的望远镜，我们也无法看见黑洞。它们是存在宇宙中的黑点，其引力大到连光线都无可避免被吸入。藉由计算机仿真这些谜样的物体，科学家逐渐了解许多宇宙依赖《黑洞》的地方。

外星人是否存在有诸多争议。如果真有外星人，SETI（寻找外层空间高等生物计划）的人应该会最先知道。这个团体由科学家和业余天文爱好者所组成，他们试图找出太空中有外星生物的证据，为此，他们运用大量的碟形卫星天线和先进的计算机科技。今日，这些科技被用来继续人类数十年来寻找《外层空间高等生物》的工作。

你以为自己够了解外层空间了？也许还有更多你所不知道的等待发掘。就让国家地理频道的《太空搜密》，为你呈现一些宇宙中最令人难以置信且意想不到的部分。
