2020考研英语双语阅读之NASA发现超级地球或存在生命篇 如果要想提高我们的英语阅读能力，经常看一些双语阅读文章是一个不错的选择。为此出guo了“2020考研英语：双语阅读之NASA发现超 级地球 或存在生命篇”的文章，希望对大家有所帮助。 以下是2020考研英语：双语阅读之NASA发现超 级地球 或存在生命篇的具体内容： NASA发现超 级地球 或存在生命 After pleting its first year of observations in the southern sky， NASAs Transiting ExoplaSurvey Satellite has spotted some intriguing new exoplas only 31 light-years away fromEarth. 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。 Multiple exoplas - plas orbiting stars outside our solar system - were discoveredorbiting an M-dwarf star， called GJ 357 in the Hydra constellation. The star is 40% cooler thanour sun and only about a third of the suns mass and size. A study describing the three plaswas published this week in the journal Astronomy & Astrophysics. 科学家发现了数颗围绕着长蛇座M矮星GJ 357运行的系外行星，系外行星指的是围绕太阳系外恒星运行的行星。这颗恒星的温度比太阳低40%，质量和体积只有太阳的三分之一左右。一项描述这三颗行星的研究本周发表在天文学与天体物理学期刊上。 The first exopla 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GJ 357 b。 The exopla is 22% larger and 80% more massive than Earth， making it a super-Earth. Theresearchers estimate that it has an average temperature of 490 degrees Fahrenheit. Itpletes one orbit around the star every 3.9 days. 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”。研究人员估计它的平均温度为490华氏度（约合254摄氏度）。这颗行星的公转周期为3.9天。 We describe GJ 357 b as a hot Earth， said Enric Pall， study co-author and astrophysicist atthe Institute of Astrophysics of the Canary Islands. Although it cannot host life， it isnoteworthy as the third-nearest transiting exopla known to date and one of the best rockyplas we have for measuring the position of any atmosphere it may possess. “我们将GJ 357 b描述为一个热地球，”研究的合作者、加那利群岛天体物理研究所的天体物理学家恩里克怕列说。“尽管它不能承载生命，但值得注意的是，它是迄今为止已知的第三近程过境系外行星，也是可以用来测量其拥有的任何大气成分的最 佳岩质行星之一。” The researchers also discovered more signals of exoplas in the system. 研究人员还在星系中发现了更多系外行星的信号。 GJ 357 d， a super-Earth that is 6.1 times the Earths mass， is the most intriguing because itorbits the star at a distance where the temperature might be just right to support liquidwater on the surface. 另一颗“超 级地球”GJ357d的质量是地球的6.1倍，最令研究人员感兴趣，因为它围绕恒星运行的距离使其表面的温度可能刚好适宜液态水的存在。 GJ 357 d is located within the outer edge of its stars habitable zone， where it receives aboutthe same amount of stellar energy from its star as Mars does from the Sun， said DianaKossakowski， study co-author at the Max Planck Institute for Astronomy. If the pla has adense atmosphere， which will take future studies to determine， it could trap enough heat towarm the pla and allow liquid water on its surface. “GJ 357 d位于其恒星宜居带的外边缘，它从恒星接收到的能量与火星从太阳接收到的能量差不多，”马克斯普朗克天文研究所的研究合著者戴安娜科萨科夫斯基说。“如果这颗行星有稠密的大气层，它可能会捕获足够的热量使自身变暖，表面就可以留存液态水，而是否存在大气层还需要进一步研究。” The researchers dont know if the super-Earth is rocky like our own pla， but it orbits thestar every 55.7 days and has a temperature of negative 64 degrees Fahrenheit. Anatmosphere could cause it to be warmer. 科学家尚不清楚这颗“超 级地球”是否和地球一样属于岩质行星，但它的公转周期为55.7天，温度为零下64华氏度。如果行星上有大气层，温度会更高 。 This is exciting， as this is humanitys first nearby super-Earth that could harbor life - uncovered with help from TESS， said Lisa Kaltenegger， study author， associate professor ofastronomy and director of Cornells Carl Sagan Institute. With a thick atmosphere， thepla GJ 357 d could maintain liquid water on its surface like Earth and we could pick outsigns of life with uping telescopes soon to be online. 研究报告的撰写者、天文学副教授、康奈尔大学卡尔萨根研究所所长莉萨柯廷安说：“这很令人兴奋，因为这是人类在TESS的帮助下发现的第一颗可能存在生命的近距离超 级地球。如果存在稠密的大气层，行星GJ357 d可能像地球一样表面可留存液态水，我们或许可以通过即将上线的望远镜找到生命的迹象。 If GJ 357 d were to show signs of life， it would be at the top of everyones travel listand wecould answer a 1，000-year-old question on whether we are alone in the cosmos. “如果GJ 357 d行星上有生命迹象，它将成为每个人旅行清单上的第一目的地，那个困扰我们上千年的问题或许也将有答案，那个问题就是：人类是不是宇宙中唯一存在的生命。” In the middle of those two
