The Smithsonian's Robert Noyes told a news conference ,"The planet is the largest planet that has ever been seen, inside our solar system or out, and it's the least dense planet."

史密森尼学会的 RN 在一个新闻发布会上谈到：这是迄今为止所发现的最大的行星，不论在太阳系内还是外太阳系外，也是密度最小的行星。

Planetary nebulas - so called because some of them resemble a planet when viewed through a small telescope - are produced in the late stages of a sun-like star's life.

行星状星云得名的原因是外观在小望远镜中类似行星，是类太阳恒星在演化后期产生的。

Planetary nebulas - so called because some of them resemble a planet when viewed through a small telescope - are produced in the late stages of a sun-like star's life.

因其外观在小望远镜中类似行星，故名行星状星云。它们产生于类太阳恒星生命的最后阶段。

Only when two planets revolves around one gravitation center, there exists the two process, and revolving time of the two process is complete same, but the direction of quadrature component deflecting orbital plane is complete opposite and values of quadrature component aren't equal.

15摘 要：本文通过建立一个行星绕太阳运行的模型，发现行星在绕太阳的过程存在同向绕行和异向绕行过程，只要两颗天体同绕一个吸引中心，就存在这样的过程，这两个过程的运行方向完全相反，运行时间完全相同。

Of course , in this well-studied example of a planetary nebula , the glowing material does not come from planets .

当然，这个已被仔细研究了的行星状星云范例，其中炽热的物质不是来源于行星。

Of course, in this well-studied example of a planetary nebula , the glow in g material does not come from planets.

当然，这个已被仔细研究了的行星状星云范例，其中炽热的物质不是来源于行星。

Of course , in this well-studied example of a planetary nebula , the glowing material does not come from planets .

当然，在这个被细致地研究过的行星状星云样本中，炽热的物质并非来自行星，而是一颗正在死亡的太阳型恒星向外扩散的气壳。

Just a fortnight ago, astronomers using the Hubble space telescope identified water vapour in the atmosphere of an exoplanet, albeit a gaseous exoplanet some 150 light years away.

就在两周前，天文学家使用哈勃太空望远镜，在一颗外星行星的大气中确定了水蒸气的存在，尽管该行星离我们有大约150光年。

Research has been done on the coupling form between the two-row planetary gear train and the shift restriction based on the matrix,and then the method of establishing mathematics model has been presented to analyze the planetary gear transmission using MATLAB.

在设计自动变速器时，总体结构方案主要由行星齿轮变速机构确定，因此，研究行星齿轮机构传动方案的结构特征，对其所有可能的方案进行分析，是理想的设计途径。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
