外行星

The planet's temperature is around 260 degrees, but that's cool by comparison to other exoplanets.

这颗行星的温度为260度，但与其它系外行星相比，它算是凉的。

Astronomers led by Fritz Benedict and Barbara McArthur, of the University of Texas, Austin, examined the Earth's nearest known exoplanet neighbour—a gaseous giant orbiting the sun-like star Epsilon Eridani, 10.5 light years away in the constellation Eridanus.

在弗里兹·本尼迪特和芭芭拉·麦克阿瑟带领下，得克萨斯大学的天文学家们探测了一颗系外行星，这是已知的系外行星中离地球最近的一颗。

Mayor said many more planets meeting scientists' requirements for habitability would be found, but that that the most significant short-term discovery would be that of a low-mass planet even more similar to Earth.

梅杰说，将有很多符合科学家对可居住性要求的行星被发现，但最为重大的短期发现为该与地球极为类似的小型行星的发现。581c约为地球的5倍重，但仍是目前发现的最小的外行星。

Sometimes, they happen to see the orbits of exoplanets edge-on. In those cases, the planet alternately shows more of its dayside and then more of its nightside as it circles its star.

有时，天文学家们碰巧从侧面观察到系外行星的轨道，在这种情况下，行星在围绕恒星旋转的时候就会交替地呈现出有时光面较多、有时暗面较多。

The recent batch of exoplanets were all spotted with the High-Accuracy Radial-Velocity Planet Searcher, a 3.6-metre telescope and spectograph perched atop La Scilla mountain at the southern edge of Chile's Atacama Desert.

最近一批系外行星全部是科学家利用高精确度视向速度行星搜寻器发现的。

According to Farihi and his team, studying white dwarf stars is a good way to study planetary systems outside of our own Solar System.

根据Farihi团队的研究，白矮星周围的行星系统是了解太阳系外行星的一个好途径。

Today, at an international ESO/CAUP exoplanet conference in Porto, the team who built the High Accuracy Radial Velocity Planet Searcher, better known as HARPS, the spectrograph for ESO's 3.6-metre telescope, reports on the incredible discovery of some 32 new exoplanets, cementing HARPS's position as the world's foremost exoplanet hunter.

今天，在波尔图市召开的ESO/CAUP系外行星会议上，高精度径向速度法行星搜寻光谱仪研究团队宣布，他们新发现了32颗系外行星。

To accomplish this, scientists focused the telescope on two of the 14 extrasolar planets that are known to pass directly in front of their star when observed from Earth.

为实现这一目标，科学家将望远镜锁定在14颗太阳系外行星中的两颗上，这些行星是已知的从地球可以看到其直接从它们的主星前面经过的系外行星。

Transits of exoplanets are rare. Even among those that tightlycircle their parent star, only 10% would be expected to transit in the Earth'sline of sight.

系外行星凌日现象是罕见的，即使是那些紧密围绕母恒星公转的行星，在地球上也只能探测到其中10%的行星可能会有凌日现象。

Generally, the best time to observe an outer planet like Jupiter is when the planet is retrograding. That's because then it is roughly opposite the sun in Earth's sky. This causes it to be brighter (think of it as full like the full moon), and be visible longer at night.

一般来说，想观测像木星这样的带外行星，最好就是当它出现向后运行现象的时候，这是因为此时在地球上的我们会看到行星是与太阳相对的，这也导致行星更亮（想象它就像满月那样又圆又亮），而且在夜晚出现的时间也变长。

Methods: Five patients with parkinsonism or dystonia were assigned to general anesthesia using an modified endotracheal tube.

本实验依照人体实验之相关规定进行，五位患有帕金森氏症或肌张力异常的病人接受神经立体定位手术。
