此外，斯考特还查了另一层路标：绕行银河系球状星脉冲星。

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，以于天文学家甚认为它可能正在形成球状星过程中！

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

“我什么都懂，但这意味着我什么都懂。”

Unlike open clusters, though, globulars are old.

过，与开放星同，球状星很古老。

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

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

球状星比银河系更古老恒星，既美丽又神秘，而且简直制造毫秒脉冲星工厂。

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

我之所以知道这一点，因为在大多数球状星中，质量最大恒星质量都比太阳质量小。

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 这样球状星进一步散布着黑洞，基本上，存量就会爆炸。

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

因为球状星太老了，它包含了很多死亡恒星。

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

球状星中恒星往往也含有较少重元素，如果它很老话，这也你所期望。

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。

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

剩下正常恒星都小质量红色恒星，所以球状星看起来都红色。

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，它太可能形成像地球这样行星。

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.

在青绿丛中，垂下粗大球形果子，约一分米大，外表凹凸平，好像六角形。

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

球状星更大，有几十万颗恒星，而且更像球状。

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

尽管球状星比开放星大，但球状星拥有更多恒星，密度也更大，这也它比开放星寿命更长原因之一。

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，但球状星中恒星非常紧密地聚集在一起，因此碰撞更为常见。
