Globular clusters were a good clue that there was more going on.

星团是一个很好线索，说明还有更多秘密等待着我们去发掘。

Open, or galactic clusters, and globular clusters.

开放星团或疏散星团，以及星团。

Speaking of which, most of the globular clusters orbiting the Milky Way are in the halo.

说到这，大部分环绕银河系星团都在光晕之中。

In addition, Scott included another layer of signposts: pulsars in globular clusters orbiting the Milky Way.

此外，斯考特还查了另一层路标：绕行银河系星团里脉冲星。

Unlike open clusters, though, globulars are old.

不过，与开放星团不同是，星团很古老。

It's producing so many stars that astronomers think it may be in the process of forming a globular cluster!

它产生了如此多恒星，以至于文学家甚至认为它可能正在星团过程中！

“We don't know everything, but that doesn't mean we know nothing, ” reminds a globular character on a few occasions.

“我们不是什么都懂，但这不意味着我们什么都不懂。”

First of all, the stars in a globular cluster aren't exactly like our good old Sun.

首先，星团中恒星并不像我们善良老太阳。

We know this because in most globulars, the MOST massive stars are LESS massive than the Sun.

我们之所以知道这一点，是因为在大多数星团中，质量最大恒星质量都比太阳质量小。

Because globulars are so old, they contain a lot of dead stars.

因为星团太老了，它们包含了很多死亡恒星。

Ancient clumps of stars that predate the Milky Way, globular clusters are gorgeous and mysterious, and they are veritable millisecond pulsar factories.

星团是比银河系更古老恒星团，既美丽又神秘，而且简直是制造毫秒脉冲星工厂。

Natarajan: If those globular clusters like Pal 5 are further littered with black holes, the inventory just explodes, basically.

Natarajan：如果像 Pal 5 这样星团进一步散布着黑洞，基本上，存量就会爆炸。

What normal stars are left are low mass red stars, so globulars tend to look red.

剩下正常恒星都是小质量红色恒星，所以星团看起来都是红色。

The stars in globular clusters tend to have less heavy elements in them too, which you expect if they're old.

星团中恒星往往也含有较少重元素，如果它们很老话，这也是你所期望。

The globular young man, red with annoyance, had torn himself from his family and was hastening across the room to her.

圆圆年轻人气得满脸通红， 他从家人身边挣脱出来， 急忙穿过房间向她走去。

Because globular stars lack heavy metals, it's unlikely they would've formed planets like Earth.

因为恒星缺乏重金属，它们不太可能像地这样行星。

Globular clusters are larger, have hundreds of thousands of stars, and are more spherical.

星团更大，有几十万颗恒星，而且更像。

From its mass of greenery, huge globular fruit stood out, a decimeter wide and furnished on the outside with creases that assumed a hexangular pattern.

在团团青绿丛中，垂下粗大果子，约一分米大，外表凹凸不平，好像六角。

Such collisions are extremely rare in space, but the stars are so tightly packed in globulars that collisions are more common.

这样碰撞在太空中极为罕见，但星团中恒星非常紧密地聚集在一起，因此碰撞更为常见。

Despite being larger than open clusters, globulars have more stars and are denser, which is one reason they live longer than open clusters.

尽管星团比开放星团大，但星团拥有更多恒星，密度也更大，这也是它们比开放星团寿命更长原因之一。
