查询词典 light years

For many years, right up until the launch of the Hubble telescope - the range of measured values for the expansion rate was from 50 to 100 kilometers per second per megaparsec (a megaparsec, or mpc, is 3.26million light-years).

但直到哈勃望远镜发射前，哈勃常数的值还在每百万秒差距50~100km/s这么大范围内（百万秒差距缩写为mpc，相当于326万光年）。

So, using infrared light, astronomers have just found a small galaxy of about a billion stars in the constellation Canis Major, that is -- astonishingly -- only about 25,000 light-years away from the Sun.

碰巧，通过红外线，天文学家已经发现了一个较小的由数十亿恒星组成的名为&Canis Major&星座的星系，这是非常令人惊讶的！

The Hubble images show the planet, named Fomalhaut b, as a tiny point source of light orbiting the nearby, bright southern star Fomalhaut, located 25 light-years away in the constellation Piscis Australis.

这张哈勃的图像显示的是一颗名为Fomalhaut b的行星，在轨道附近就像一个小点，它坐落造位于25光年外的南鱼座。

The new infrared image shows the object as a speck of light near the star Beta Pictoris , which is 70 light-years from Earth, toward the constellation Pictor.

这张新的红外线图片显示，该物体就象一个光点位于绘架座β星附近。绘架座β星距地球70光年，位于绘架座。

As their light zips across billions of light-years to Earth, the gravity of matter along the way stretches, splits, and contorts their images.

这是因为当它们发出的光线跨越数十亿光年到达地球的时候，其图象可能会由于沿途的物质引力作用而被拉伸、撕断或扭曲。

This star-forming nebula, which lies 5,000 light-years away in the constellation Monoceros, is named for its rosebud-like shape when seen using only optical light.

这个恒星形成星云，它是5000个光年之遥，在星座Monoceros ，命名为蔷薇花蕾般的形状时，看时只用视力的光。

The data showed that the light from the supernovas had traveled nearly 11 billion light-years to reach Earth.

资料表明来自这些的光线穿行了将近110亿年才到达地球，这意味着爆炸是110亿年前发生的，而爆炸之光却刚刚到达我们这里。

Using existing observations, the researchers analyzed the polarized light emissions from 25 dense areas within several nebulas that are up to 6500 light-years from Earth.

研究人员利用现有的观测资料，对距地球6500光年以外的几团星云内部中25个高密度区域所释放的偏振光进行了分析。

Using data collected from previous sky surveys, the researchers analyzed the polarized light emissions from 25 dense areas within several molecular clouds, or nebulas, which are up to 6500 light-years from Earth.

使用从以前的天空调查所收集的数据，研究人员分析了来自25多个密集地区分子云内，或星云，这是高达6500光年的距离地球年偏振光排放。
