　　A radar image of Mercury’s North Polar Region acquired by the Arecibo Observatory in Puerto Rico is shown superposed on a mosaic of Mercury MESSENGER images of the same area in this NASA handout photo released Nov 29, 2012. Yellow areas denote regions of high radar reflectivity.
　　图释：以上是由波多黎各的阿雷西博天文台收集的一张水星北部极地地区的雷达图片。它与2012年11月29日美国宇航局发布的一张信使号太空船在同一地区收集的加了马赛克的资料图片反映的信息重复了。黄色区域表示雷达高反射率地区。

　　(China Daily) Despite searing daytime temperatures, Mercury, the planet closest to the sun, has ice and frozen organic materials inside permanently shadowed craters in its north pole, NASA scientists said on Thursday.
　　（中国日报）美国宇航局科学家周四表示，离太阳最近的星球水星，尽管有炽热的日间温度，但是在它的北极的永久阴影区的陨石坑中有冰和凝固的有机物质。

　　Earth-based telescopes have been compiling evidence for ice on Mercury for 20 years, but the finding of organics was a surprise, say researchers with NASA’s MESSENGER spacecraft, the first probe to orbit Mercury.
　　第一个探测水星轨道的是美国宇航局的信使号太空飞船，它的研究人员表示，地面望远镜已经花了20年的时间收集证据表明水星上有冰，但是发现有机物确实是个意外。

　　Both ice and organic materials, which are similar to tar or coal, were believed to have been delivered millions of years ago by comets and asteroids crashing into the planet.
　　冰和有机物质，类似于柏油和煤炭，被认为是百万年前由彗星和小行星与水星碰撞时产生的。
