They show about 100,000 star clusters and millions, or even billions, of individual stars.

它们展示了大约10万个星团和数百万甚至数十亿颗恒星。

If galaxies were high school lunchrooms, the star cluster named HVGC-1 would be a social pariah.

如果说银河系是学校食堂，HUGC-1 星团就像是一个餐厅里不受欢迎的学生。

Yeah, there's a new moon, so it's the perfect night to observe faint star clusters.

是新月，所以今晚特别适合观测微弱的星团。

The discovery of planetary material thus raises more questions. Are star clusters indeed inhospitable to planets?

行星物质发现也因此产生了许多问题。星团确实不适合行星吗？

We saw this in the last episode; the dust surrounding the Pleiades star cluster is a reflection nebula.

我们在上一期看到过；昴宿星团周围的尘埃是一个反射星云。

Astronomers identified the silicon-rich rocky material by training the Hubble Space Telescope on the nearby Hyades star cluster.

天文学家通过培训哈勃望太空远镜观测附近的毕宿星团来确认富含硅元素的岩石物质。

In the bull's shoulder you can find the Pleiades, a bright star cluster recognized by stargazers for thousands of years.

在牛的肩膀处你可以找到昂宿星团，这个明亮的星团被观星者观察了几千年。

Galaxies, nebulae and star clusters have been seen like never before.

星系、星云和星团以前所未有的方式出现。

We've sent radio waves like the Arecibo message  and the Cosmic Call to distant star clusters.

我们已经向遥远的星团发送了诸如阿雷西博信息和宇宙呼唤之类的无线电波。

Intagliata:  And it's also suggestive of just how much we could be missing in other star clusters like Pal 5.

Intagliata：这也暗示了我们在 Pal 5 等其他星团中可能遗漏了多少。

It's been thought to have two for a long time, but a recent study of the locations of star clusters seems to indicate there are actually four!

长期以来，人们一直认为它有两个，但最近对星团位置的研究表明，实际上有四个！

There are about 150 star clusters in our galaxy, the Milky Way. In most of them, star formation stopped over 10 billion years ago.

在我们的银河系中大约有150个星团，银河系。在它们中的大多数中，恒星形成在100多亿年前就停止了。

The Pleiades are one of the closest and brightest star clusters in the sky, made of hot blue stars surrounded by a dust cloud that reflects their light.

昴宿星团是天空中彼此距离最近也最明亮的星团之一，由蓝热星组成，被能反射它们光芒的尘雾包围。

Intagliata:  Now researchers in Europe claim to have stumbled upon an unexpected trove of these stellar-mass black holes—in a puffy star cluster called Palomar 5.

Intagliata：现在，欧洲的研究人员声称在一个名为 Palomar 5 的蓬松星团中意外发现了这些恒星质量黑洞的宝库。

The Milky Way is a spiral galaxy that both the Sun and solar system are a part, along with a bunch of stars clustered together that create a brightly lit center.

银河系是一个螺旋星系，太阳和太阳系都是它的一部分。除此以外，还有一群恒星聚集在一起，形成了一个明亮的中心。

Like star clusters, galaxies in galaxy clusters are bound to the cluster by their own mutual gravity, and move through the cluster on long orbits that can take billions of years to complete.

就像星团一样，星系团中的星系通过自身的相互引力与星系团结合在一起，并沿着可能需要数十亿年才能完成的长轨道在星系团中移动。

Scientists have observed BZ with ground-based telescopes in the American states of Hawaii and Arizona. They said BZ apparently left its home star system when the star system interacted with other systems in a tight fitting star cluster.

在美国夏威夷州和亚利桑那州，科学家们用地面望远镜观测到了BZ。他们说，很明显，BZ所在星系与其他星系的星团相互作用后，BZ离开了它所在星系。
