Is There a Hidden ''Super-Earth'' Exoplanet Orbiting Our Closest Stellar Neighbor?

存在一个绕着离我们最近的恒星运行的隐藏着的“超级地球”吗？

Scientists have found evidence of a new exoplanet candidate orbiting our closest stellar neighbor, Proxima Centauri.

科学家们已经发现了绕着离我们最近的恒星——比邻星运行的一颗系外行星。

This exoplanet candidate, Proxima c, likely has a mass six times that of Earth.

这颗系外行星叫做比邻c行星，它的质量差不多是地球质量的六倍。

But it''s unlikely that life would survive on the planet, given its frigid temperatures.

但是看上去在那个行星上没有生命存在，因为那里的温度太低了。

But because Proxima Centauri is a relatively dim star, Proxima c is likely to be an extremely frigid world. Temperatures on the planet could dip as low as -388 degrees Fahrenheit, Space.com reports. It''s unlikely we''d find life on such a chilly world.

但是由于比邻星是一颗相对暗淡的恒星，所以比邻星c行星可能是一个极度寒冷的世界。这颗行星上的气温可能会低至零下388华氏度。或许我们不可能在如此严寒的世界里找到生命的迹象。

An international team of researchers analyzed 17 years worth of data from the HARPS (High Accuracy Radial Velocity Planet Searcher) and the UVES (Ultraviolet and Visual Echelle Spectrograph)—both of which are installed on European Southern Observatory telescopes in Chile. The scientists noticed that Proxima Centauri experienced an unexplained wobble that could be explained by the gravitational tug of another planet.

一个国际研究团队分析了17年来自位于智利的欧洲南方天文台的HARPS光谱仪和紫外可见分光光度计的数据。科学家们注意到比邻星正在经历无法解释的不稳定期，这可能是由于另一颗行星对它产生的重力场造成的。

For now, Proxima c remains only an exoplanet candidate as scientists train additional planet-hunting instruments on the star system to confirm the obxt''s existence. But such a startlingly discovery so close to home would show just how much more there is to learn about the stars lying in our cosmic backyard.

现在，比邻星c星只是入选了可能宜居的系外行星的候选名单，因为科学家们还在用行星观测设备来确认这颗星球是否存在。但是这样一个惊人的发现（这颗行星离我们的地球如此之近）也提醒着我们那些离我们的星系近的那些星球还有很多值得我们去探索的地方。

What causes a planet to be tidally locked?

是哪些原因会导致一颗行星出现潮汐锁定现象呢？

It makes no sense to call it a super earth when the gravity is a crushing six times greater and it’s too cold to support life

如果一颗行星的重力糟糕到是地球的六倍大并且上面的气温严寒到不适合生命存活，那么是不适合将其称之为“超级地球”的。

NASA will send the Enterprise at warp speed to look for life.

美国宇航局会迅速让一些企业探索外太空、寻找其它星球上的生命。

How many new planets have been discovered in recent years? Yet they still want to teach our kids in school theres only 9 planets. How many other lies are they teaching our kids?

在最近几年有多少新行星被发现了呢？可我们还是在学校里教我们的孩子们说行星只有9颗。那些老师还在教我们的孩子多少其它的错误的知识呢？

Is there a news article based on actual facts anymore??

世界上还有没有哪篇文章是基于事实的呢？

An astronomer I know has told me that anything with more than about 2.5 times the mass of Earth will not be a rocky planet (like Earth), but will instead be an ice giant or a gas giant. It has to do with the nature of planet formation, but there aren''t going to be any ginormous earth-like rocky planets with water and land and atmosphere remotely like ours.

我认识的一名天文学家对我说任何天体，只要它的质量超过了地球的2.5倍，它就一定不会是一颗岩石固体行星（就像地球这样），在这么大的质量条件下，它可能会是一颗充满了冰雪的巨行星或者是一颗气态巨行星。我们必须考虑到行星形成的一些规律，宇宙中不存在像我们的地球一样的巨大的类似于地球的拥有水和陆地和大气层的其它行星。

I find it odd that suddenly we are finding a lot of earth like planets...... Did someone turn the drip feed disclosure tap up to run?

我们居然突然间找到了那么多像我们的地球一样的行星，而且我们还不断发现这种行星，这种事在以前从未有过。我觉得这种事实在是很奇怪。难道是有人打开了行星观测的“滴水的水龙头”吗？
