exoplanet

In February NASA will decide whether to pay for a new planet-hunting spacecraft called the transiting exoplanet survey satellite ( TESS ) .

在明年二月，美国航空航天局将会决定，是否会再投资建造一个新寻找行星太空船“检测过境系外星球卫星（tess）”。

Both of these effects could potentially be detected from an exoplanet .

这两种效应都很有可能被地外星球上的外星人探测到。

Step one : examine the Earth as if it were an exoplanet .

步骤一：把地球当做一个（太阳）系外行星进行研究。

The first exoplanet discovered around the star was GJ 357 b.

科学家发现的首颗围绕这颗恒星运行的系外行星是GJ357b。

This makes it impossible for life to exist on the exoplanet , according to NASA .

美国宇航局称，这种近距离不可能让“开普勒-10b”上有生命迹象。

The exoplanet Fomalhaut b was the first one photographed with visible light .

这个名为“北落师门b”的系外行星是第一个用可视光拍到的行星。

The exoplanet , called WASP 12 b , is a gas giant , like Jupiter .

这颗被称为WASP12b的地外行星是一个巨大的气体行星，就像木星那样。

But the presumably rocky composition can be hypothesized simply based on the exoplanet 's size .

但我们可以根据它的大小判断出这很有可能是一颗岩石行星。

The sighting made big news , because almost all exoplanet discoveries before or since were indirect detections .

这一发现引起轰动，因为此前几乎所有系外行星的发现都是间接探测到的。

And a recently discovered exoplanet orbiting a red dwarf had some Earth-like qualities .

而近期一项研究发现了在红矮星周围绕轨道运行的系外行星有着和地球相似的特征。

NASA 's best exoplanet hunter is limping into retirement .

NASA最好的行星探索望远镜慢慢退役。

LTT 1445Ab is very different from the 2016 discovery of HD 131399Ab , another exoplanet with three suns .

LTT1445Ab与2016年发现的另一个有“三个太阳”的系外行星HD131399Ab差别很大。

This is quite remarkable in view of the fact that the discovery of the first exoplanet was confirmed only in the mid-1990s .

鉴于二十世纪九十年代中期才确定发现了第一颗外星星球，这相当值得一提。

The ultimate aim of Kepler is to search extrasolar lives , so it is necessary to study exoplanet atmosphere in detail .

Kepler计划的最终目的是寻找系外生命，这就要求深入的研究系外星大气。

The other group favors the hypothesis that Fomalhaut b is an exoplanet , albeit one shrouded in dust .

另一组更倾向于“北落师门b”是笼罩在尘云中的系外行星这一假设。

The first exoplanet discovered in the habitable zone could be a mirage , according to reports from an exoplanet meeting yesterday .

昨天召开的外行星会议陈述称，在太阳系外的“适宜栖身带”发现的首个系外行星可能只是个海市蜃楼。

Researchers found the exoplanet while looking at the star HIP 13044 or Sergio , for Star of Extra-Galactic Origin .

研究人员是在研究HIP13044恒星的时候发现了这颗太阳系外行星。恒星HIP13044又名Sergio（塞尔吉奥），取在银河系外起源的恒星之意。

The exoplanet is 22 % larger and 80 % more massive than Earth , making it a super-Earth .

这颗系外行星体积比地球大22%，质量比地球高80%，使之成为“超级地球”。

A super-Earth is an exoplanet that is up to 10 times more massive than our Earth .

超级地球是指体积比地球大十倍的太阳系外行星。

Known as HD 131399Ab , the unusual exoplanet is located 320 light-years from Earth in the large southern constellation Centaurus .

这颗不同寻常的地外行星被命名为HD131399Ab，它位于南方巨大的人马星座上，距地球320光年。

This " super-Earth " is a recently discovered exoplanet that is in its star 's habitable zone .

这颗“超级地球”是最近发现的太阳系外行星，它位于其恒星的宜居带内。

With the improvement of the observational accuracy and the diversity of observational methods , exoplanet researches will advance from statistics to specifics , from simpleness to details .

随着观测精度的提高和观测手段的多样性，系外行星的研究将由统计到具体，由粗略到细微。

Finding Goldilocks planets closer to home will be the job of TESS , the Transiting Exoplanet Survey Satellite , scheduled to be launched in 2017 .

寻找离地球较近的适居带行星将是凌日系外行星勘测人造卫星（TransitingExoplanetSurveySatellite，简称TESS）的任务。这种卫星将于2017年发射。

But with a mass around seven times greater than the Earth , and hence a much higher density , it implies that the exoplanet is probably made of rock with a dense iron core .

但是它的质量大约是地球的7倍，所以密度要比地球高得多，这意味着这颗外部行星很有可能是由内核为高密度铁的岩石组成。

Because astronomers have found the first carbon-rich exoplanet , with more carbon than oxygen in its atmosphere - instead of the 1 to 2 carbon to oxygen ratio found in our solar system .

因为天文学家发现了第一个富含碳的系外行星，其大气中碳含量远超过氧含量，而非太阳系的1:2碳氧比。

Because astronomers have found the first carbon-rich exoplanet , with more carbon than oxygen in its atmosphere & instead of the1 to2 carbon to oxygen ratio found in our solar system .

因为天文学家发现了第一个富含碳的系外行星，其大气中碳含量远超过氧含量，而非太阳系的1：2碳氧比。

While most of the exoplanets found so far are hellishly hot , OGLE-2005-BLG-390L b has the distinction of being the coldest exoplanet yet discovered .

到目前为止，绝大多数发现的外部行星都是可怕的炎热，OGLE-2005-BLG-390Lb却很特别，它是至今发现的最冷的外部行星。

Chinese researches who are banned from attending a NASA conference on exoplanet research have received a letter of clarification from the committee organizing the event informing them of a revised decision .

被禁止参加美国航空航天局外星球研究大会的中国研究人员，日前收到了组委会的澄清信，通知他们修改后的决定。

After completing its first year of observations in the southern sky , NASA 's Transiting Exoplanet Survey Satellite has spotted some intriguing new exoplanets only 31 light-years away from Earth .

美国宇航局的过境系外行星测量卫星（TESS）在完成对南半球天空的第一年观测后，发现了几颗距离地球仅31光年的有趣的新系外行星。

Q. Let 's assume there 's life on the nearest habitable exoplanet and that they have technology comparable to ours . If they looked at our star right now , what would they see ?

Q.不妨假设在离我们最近的一颗适于居住的地外星球上有生命存在，而且他们拥有和我们人类相近的科技。如果他们现在朝我们这边看过来，会看到什么？
