Such is the case for a nearby star called TW Hydrae.

一颗被称作长蛇座TW的邻近恒星也属于这类情况。

They can glow on their own or reflect light from nearby stars.

它们可以自己发光，也可以反射附近恒星的光。

It will not be we who reach Alpha Centuri and the other nearby stars.

我们这一代不会到达阿尔法星座的，或是任何它附近的行星。

In the past year, the Kepler space observatory has found hundreds of planets just around nearby stars.

在过去的时间里，开普勒空间瞭望台发现了几百颗行星在恒星附近环绕。

Instead of pointing Hubble's eye at nearby stars or distant formations, Robert Williams wanted to peer into the void.

并不是用哈勃望远镜指向附近的星星或者遥远的星型，罗伯特·威廉姆斯想要探索空洞。

But now we also see a planet bathed in the light of a nearby star: the Sun.

太阳。

For a long time, astronomers looked really hard for this motion in nearby stars.

很长一段时间以来，天文学家一直在努力寻找邻近恒星的这种运动。

That meant thousands of stars, galaxies, and other objects nearby were candidate progenitors of the detected bursts.

这意味着附近的数千颗恒星、星系和其他物体都是探测到的伽玛射线爆的候选祖先。

At just about the same time, astronomers found that another nearby star, called Gliese 229, had an extremely faint companion.

几乎与此同时，天文学家发现了附近的另一颗名为 Gliese 229 的恒星，它有一个极其暗淡的伴星。

Still, this method only works for relatively nearby stars, ones that are less than about 1000 light years away.

不过，这种方法只适用于相对较近的恒星，即距离我们不到1000光年的恒星。

There are plans to construct Dyson Spheres, of varying sizes, in nearby star systems as well.

还有计划在附近的恒星系统中建造不同大小的戴森球。

I hope we're traveling frequently throughout the solar system, perhaps preparing for missions to nearby star systems.

我希望我们经常在整个太阳系旅行，也许是为前往附近恒星系统的任务做准备。

They might even be able to reach the nearby star system Alpha Centauri only 15 years after they launch.

他们甚至可能在发射 15 年后到达附近的恒星系统半人马座阿尔法星。

Another goal will be to search for and study asteroids that threaten to strike the Earth or to look for nearby stars and planets.

另一个目标是寻找和研究有撞击地球威胁的小行星或寻找附近的恒星和行星。

Nearly all astronomical objects in space emit radio waves, whether nearby stars, objects in far away galaxies, they all give off radio waves.

太空中几乎所有的天体都会发射无线电波，无论是附近的恒星，还是遥远星系中的物体，它们都会发射无线电波。

But then something happened: perhaps the shockwave from a nearby exploding star slammed into it, or maybe another cloud lumbered by and rammed it.

也许是周边爆炸的恒星产生的冲击波撞上了它，又或者是另一团云轰隆轰隆地经过并撞了上去。

While EMISSION nebulae glow due to their own light, REFLECTION nebulae are bright because — can you guess? — they reflect the light of nearby bright massive stars.

发射星云由于自身的光线而发光，而反射星云之所以明亮，是因为——你能猜到吗？——它们反射了附近明亮的大质量恒星的光。

But you can infer that there's one in there, by looking at the pattern of the light, that does get around it from stars behind it, and nearby stars.

但是你可以通过观察光的模式推断出那里有一个，它确实从它后面的恒星和附近的恒星那里绕过了它。

Well, not all ordinary matter is glowing brightly or is illuminated by nearby stars It's not dark matter but it is ordinary matter that is just in darkness.

好吧，并不是所有的普通物质都在发光或被附近的恒星照亮。这不是暗物质， 而是处于黑暗中的普通物质。

Now, a big heavy, floating lump, it starts to orbit its nearby star, pulling anything in its path into its gravity along the way, making it even bigger and even globbier.

一个巨大、沉重、漂浮着的大块头开始围绕它附近的恒星运行，一路上把它路径上的任何东西都拉入它的引力之中，这使得它变得越来越大，也越来越呈球体。
