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

球状星团是一个好的线索，说明还有更多的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，以及球状星团。

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

说到这，大部分环绕银河系的球状星团都在光晕之中。

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：绕行银河系的球状星团里的脉冲星。

Unlike open clusters, though, globulars are old.

不过，与开放星团不同的是，球状星团。

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

产生了如此多的恒星，以至于学家甚至认为可能正在形成球状星团的过程中！

“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，球状星团中的恒星并不像我们善良的太阳。

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，是因为在大多数球状星团中，质量最大的恒星质量都比太阳的质量小。

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

因为球状星团太了，们包含了多死亡的恒星。

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

球状星团是比银河系更的恒星团，既美丽又神秘，而且简直是制造毫秒脉冲星的工厂。

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 这样的球状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.

剩下的正常恒星都是小质量的红色恒星，所以球状星团看起来都是红色的。

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

球状星团中的恒星往往也含有较少的重元素，如果们的话，这也是你所期望的。

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

圆圆的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.

因为球状恒星缺乏重金属，们不太可能形成像地球这样的行星。

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

球状星团更大，有几十万颗恒星，而且更像球状。

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.

在团团的青绿丛中，垂下粗大的球形果子，约一分米大，外表凹凸不平，好像六角形。

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

这样的碰撞在太空中极为罕见，但球状星团中的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.

尽管球状星团比开放星团大，但球状星团拥有更多的恒星，密度也更大，这也是们比开放星团寿命更长的原因之一。
