To send messages using a Cepheid, Learned and his colleagues suggest that extraterrestrials might change the star's cycle.

-
His first great discovery was made when he recognized a Cepheid variable star.
他识别出造父变星，做出了第一个重大发现，在仙女座星云的外围区域。
-
This property can be used to reveal the distance to a cepheid's parent galaxy, because the star's period reveals its intrinsic brightness.
这一特性可以用来测算出一造父变星与其源星系之间的距离，因为变星的周期能显示出其内在亮度。
-
Such stars periodically wax and wane in brightness: the longer a cepheid's period the bigger and brighter it is.
这类星的亮度有周期性盈亏：周期越长，该造父变星体积就越大，亮度也越高。
-
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。
-
Another refinement of our ladder is the fact that we have observed the Cepheids in the near-infrared parts of the electromagnetic spectrum where these variable stars are better distance indicators than at optical wavelengths.
我们这些距离台阶的另一个改进是：我们已经观测了造父变星的近红外波谱，这些变星在红外电磁波段的量天尺性能比可见光波段更好。
-
At this distance some non-variable stars may by chance appear to grow brighter and fainter in the same fashion as Cepheids due to the physical impossibility of perfect measurements of such dim objects.
在这个距离上，由于仪器的物理测量极限，测量不可能在完全理想状态下进行，某些非变星也会显得有时亮有时暗，就如同造父变星的模式似的。
-
Because NGC 4603 is much farther away than the other galaxies studied with Hubble by the Key Project team, 108 million light-years, its stars appear very faint from the Earth, and so accurately measuring their brightness, as is required for distinguishing the characteristic variations of Cepheids, is extremely difficult.
由于它远在1.08亿光年外，远超项目组团队研究的其他星系，故此恒星变得非常黯淡，而任务要求必须正确测定其中的特定变星——造父变星——的光度，显得格外困难。

cepheid：造父变星
造父变星(Cepheid)是恒星死亡前,膨胀成红巨星的必经过程,其亮度会因星体收缩与扩张而改变,当遥远的星系旋臂充满蓝色新星时,突然出现的红巨星就比较容易被看到,然而并非每次都如此幸运,大部份还是会因为周遭的星尘遮蔽了光线而看不见.
