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.

(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.
（中國(guó)日?qǐng)?bào)）美國(guó)宇航局科學(xué)家周四表示，離太陽(yáng)最近的星球水星，盡管有熾熱的日間溫度，但是在它的北極的永久陰影區(qū)的隕石坑中有冰和凝固的有機(jī)物質(zhì)。
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.
第一個(gè)探測(cè)水星軌道的是美國(guó)宇航局的信使號(hào)太空飛船，它的研究人員表示，地面望遠(yuǎn)鏡已經(jīng)花了20年的時(shí)間收集證據(jù)表明水星上有冰，但是發(fā)現(xiàn)有機(jī)物確實(shí)是個(gè)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.
冰和有機(jī)物質(zhì)，類(lèi)似于柏油和煤炭，被認(rèn)為是百萬(wàn)年前由彗星和小行星與水星碰撞時(shí)產(chǎn)生的。
