希尼爾翻譯公司（www.marshallsfreshproduce.com）2016年7月24日了解到：It has also detected nine small planets within so-called habitable zones, where conditions are favourable for liquid water - and potentially life.

NASA還在所謂的“可居住帶”內(nèi)發(fā)現(xiàn)了9顆較小的行星，就這些行星的空間位置來看，很有可能存在液態(tài)水和生命。

The finds are contained within a catalogue of 1,284 new planets detected by Kepler - which more than doubles the previous tally.

這一結(jié)果是從NASA開普勒望遠(yuǎn)鏡新發(fā)現(xiàn)的1284顆行星（兩倍多于之前發(fā)現(xiàn)的行星）中分析得出的。

Nasa said it was the biggest single announcement of new exoplanets.

NASA說這是有史以來最大的太陽系外星系發(fā)現(xiàn)報(bào)告。

Space agency scientists discussed the new findings in a teleconference on Tuesday.

周二的時(shí)候，航天局的科學(xué)家們?cè)谝粓?chǎng)電話會(huì)議上討論了這一結(jié)果。

Statistical analyses of Kepler’s expanding sample of worlds help astronomers understand how common planets like our own might be.

天文學(xué)家們對(duì)開普勒望遠(yuǎn)鏡的觀測(cè)結(jié)果進(jìn)行了統(tǒng)計(jì)分析，結(jié)果表明像地球一樣的行星在宇宙中可能非常普遍。

Dr Natalie Batalha, Kepler mission scientist at Nasa’s Ames Research Center in California, said calculations suggested there could be more than 10 billion potentially habitable planets in the Milky Way.

據(jù)加州NASA埃姆斯研究中心開普勒項(xiàng)目科學(xué)家娜塔莉·巴塔利亞博士透露，計(jì)算表明在銀河系存在有超過100億顆適合居住的行星。

"About 24% of the stars harbour potentially habitable planets that are smaller than about 1.6 times the size of the Earth. That’s a number that we like because it’s below that size that we estimate planets are likely to be rocky," said Dr Batalha.

巴塔利亞博士說：“銀河系大約有24%的恒星系統(tǒng)擁有適合人類居住的行星，這些行星都小于地球體積的1.6倍。這個(gè)數(shù)值是合適的，因?yàn)樗∮谖覀冇?jì)算出的行星處于巖石狀所必須的臨界值。”

"If you ask yourself where is the next habitable planet likely to be, it’s within about 11 light-years, which is very close."

“如果你想知道下一個(gè)適合居住的行星可能在哪，那么我告訴你它就在據(jù)我們11光年遠(yuǎn)的地方，非常近?！?span id="y4mwsemgwi0" class="style52">

Future observatories such as the James Webb Space Telescope could examine starlight filtered through the atmospheres of exoplanets for potential markers of biology.

NASA將用韋伯太空望遠(yuǎn)鏡等觀測(cè)設(shè)施對(duì)這些行星進(jìn)行進(jìn)一步的觀測(cè)，將對(duì)從這些系外行星大氣層里透過來的光進(jìn)行檢驗(yàn)，以篩選那些有可能存在生命的行星。

"The ultimate goal of our search is to detect the light from a habitable exoplanet and analyse that light for gases like water vapour, oxygen, methane and carbon dioxide - gases that might indicate the presence of a biological ecosystem," said Paul Hertz, director of astrophysics at Nasa.

NASA天體物理學(xué)主任保羅·赫茲說：“我們觀測(cè)的最終目的是探測(cè)從系外可居住行星傳過來的光，并且對(duì)其進(jìn)行透光氣體分析。我們將對(duì)氣體中的水蒸氣、氧氣、甲烷和二氧化碳進(jìn)行分析，從而推定那兒是否可能有生態(tài)系統(tǒng)的存在。”

Of the telescope’s finds to date, the planets Kepler-186f and Kepler-452b are arguably the most Earth-like in terms of properties such as their size, the temperature of their host star and the energy received from their star.

就目前的觀測(cè)結(jié)果來說，開普勒-186f和開普勒-452b是和地球最像的兩顆行星。它們的大小、中心恒星的溫度以及它們可以從其吸收到的能量都和地球相類似。

Dr Batalha said the new finds Kepler 1638b and Kepler-1229b were intriguing targets in the search for habitable planets.

巴塔利亞博士說新發(fā)現(xiàn)的開普勒-1638b和開普勒-1229b都是在尋找可居住行星過程中的有趣的目標(biāo)。

The Nasa Ames researcher said the Kepler mission was part of a "larger strategic goal of finding evidence of life beyond Earth: knowing whether we’re alone or not, to know... how life manifests itself in the galaxy and what is the diversity".

她說開普勒任務(wù)是“一個(gè)尋找地外生命證據(jù)的偉大戰(zhàn)略目標(biāo)，以求證地球是否是宇宙中唯一存在生命的行星，以求證銀河系中生命的起源，以及探究到底什么是多樣性?！?span id="y4mwsemgwi0" class="style52">

She added: "Being able to look up to a point of light and being able to say: ’That star has a living world orbiting it.’ I think that’s very profound and answers questions about why we’re here."

她補(bǔ)充說道：“從光的角度開展研究，使得我們能夠說‘圍繞那顆恒星的行星里，有一顆行星上有生命’。我認(rèn)為那樣的發(fā)現(xiàn)具有很深遠(yuǎn)的意義，而且能夠回答為什么我們?cè)诘厍蛘Q生的問題?！?span id="y4mwsemgwi0" class="style52">
