Hubble made precise measurements of Cepheid variable stars in the galaxy, highlighted by green circles in the four inset boxes.

哈勃望远镜精确测量了星系中的造父变星（四个小图中用绿色圆圈标出）。

Wendy freedman of the carnegie observatories in pasadena, california, and her colleagues used the space telescope to examine the spiral galaxy m100, in which they discovered cepheid variables.

加州帕萨迪那卡内基天文台的温迪弗里德曼和她的同事们使用空间望远镜来观察螺旋状星系m100，并在其中发现了造父变星。

Cepheid variable stars – a class of stars named in honor of Delta Cephei – serve as cosmic yardsticks, enabling astronomers to measure the distances to faraway galaxies.

造父变星——以Delta Cephei的名义命名的一类星——充当宇宙的标尺，使得天文学家可以测量与更为遥远的星系之间的距离。

The SHOES team used Hubble's Near Infrared Camera and Multi-Object Spectrometer and the Advanced Camera for Surveys to observe 240 Cepheid variable stars across seven galaxies.

SHOES团队使用哈勃望远镜的近红外相机和多目标光谱仪、高级巡天相机观测了综括7个星系的240颗造父变星。

Hubble observations of pulsating stars called Cepheid variables in a nearby cosmic mile marker, the galaxy NGC 4258, and in the host galaxies of recent supernovae, directly link these distance indicators.

哈勃望远镜观测了一个近距离的星系NGC 4258中一类被称为造父变星的脉动变星和当前的超新星，直接比对了这些距离指示器。

Baktoid closed down factories throughout the Inner Rim and Colonies regions, including plants on Foundry, Ord Cestus, Telti, Balmorra and Ord Lithone.

于是，拜托伊德工厂关闭他们在内部星系和殖民地的制造厂，其中包括位于泛德里、奥德·瑟斯图、特尔第、巴尔莫亚以及奥德·里松的车间。

Although the Deimos project culminated in the maiden voyage of the first FTL ship to Tau Ceti in 2108, the billions spent on it created resentment and even rioting in some of the poorer Alliance member-states.

尽管Deimos计划最终还是达到了终极目标——飞向Tau Ceti星系的第一艘FTL动力太空船于2018年开始了她的首航，但为之投入的数十亿经费导致了一些贫瘠的联盟加盟国的不满甚至暴乱。

Arp 256 is located in the constellation of Cetus, the Whale, about 350 million light-years away.

Arp 256位于鲸鱼座，约3.5亿光年远，是Arp的特殊星系图表的第256个。

Much of the gas in the disk of the Circinus spiral is concentrated in two specific rings -- a larger one of diameter 1,300 light-years, which has already been observed by ground-based telescopes, and a previously unseen ring of diameter 260 light-years.

在圆规座的漩涡星系中的大部分气体都与两个具体的"环"有密切的联系。那个较大的，直径大约有1，300光年，它已经被地基望远镜观测到了。而先前，我们没有观测到的那个小"环"，直径大约有260光年。

Located near the plane of our own Milky Way Galaxy, the Circinus galaxy is partially hidden by intervening dust along our line of sight.

由于靠近银盘的附近，圆规座星系就被灰尘部分的遮挡了。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
