NASA's Spitzer Space Telescope showing a band of dust around the bright star that strongly matches the contents-such as water ice, organics, and rock-of a comet busted apart in a collision.

nasa斯必泽太空望远镜的资料，资料显示这颗明亮的恒星周围环绕着一个尘埃带，其中的物质包含水冰、有机物和岩石，跟碰撞后粉碎的彗星物质极为相似。

Just a fortnight ago, astronomers using the Hubble space telescope identified water vapour in the atmosphere of an exoplanet, albeit a gaseous exoplanet some 150 light years away.

就在两周前，天文学家使用哈勃太空望远镜，在一颗外星行星的大气中确定了水蒸气的存在，尽管该行星离我们有大约150光年。

Kepler is the first telescope to be designed to find Earth-sized planets that orbit in the "habitable zone" where temperatures are neither too hot nor too cold for water to remain in its liquid state.

开普勒号则是第一个设计用来寻找地球大小的行星的望远镜，这些行星的轨道处于“可居住区域”内，温度既高也不太低，水份可以以液态形式存在，适宜生物生存。

ECONOMIST: Is there anybody out there?

The sub-millimeter radiation that the telescope will collect is usually absorbed by water, but the lack of moisture in the atmosphere will enable scientists to enjoy a clear view of the sky.

The idea that the surface of Mercury has ice has been kicking around since the 1970s, and radio telescope images in 1991 showed some signs that were consistent with there being water ice on the surface.
