查询词典 light years

The new technique reduced the distance ladder to three "rungs":(1) The distance to galaxy NGC4258 is measured using straightforward geometry and Kepler's laws;(2)Cepheids in six more distant galaxies are used to calibrate the luminosity of Type Ia supernovae;(3) The Hubble constant is measured by observing a brighter milepost marker, Type Ia supernovae, in more distant galaxies hundreds of millions of light-years away, embedded in the expanding universe.

这种新技巧简化了距离跳跃为三个&阶梯&：1、星系NGC 4258的距离采用开普勒定律和简单直接的几何方法精确测量；2、在6个更远的星系中的造父变星用来校准Ia超新星的光度；3、深嵌于数亿光年外的膨胀宇宙中的星系中的Ia超新星——一种遥远而明亮的量天尺，被用于精确测定哈勃常数。

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。

The galaxy is of type Sc and it is very nearly face-on. The distance to M51 is about 9 Mpc (or about 30 million light years), and it is moving away from us at about 500 km/s.

银河是Sc类型，而且它几乎非常面对着。M51的距离大约是9Mpc(或大约3千万光年)，而且它是以大约500 km/s速度移动远离我们而去。

However, spanning about 50,000 light-years, NGC 55 is seen nearly edge-on, presenting a flattened, narrow profile in contrast with our face-on view of the LMC.

而NGC55大约覆盖了5万光年，从侧面看去，扁平狭窄的外观与大麦哲伦星系正面外观形成鲜明的对比。

Explanation: In visual appearance, M74 is a nearly perfect face-on spiral galaxy, about 30 million light-years away toward the constellation Pisces.

正如我们所见，M74是一个几乎正面朝向我们的旋涡星系，它位于双鱼座方向，距离我们约3000万光年。

Happily, the Chinese seem to have no global pretensions One can't see them interfering in some far-distant conflict, and in both military and economic terms they are still light years behind America.

正好满足了这个过渡条件。
