So, they assigned each of us something celestial to do.

所以我们要给己分派一些角色。

In their rotational and orbital movements, stars and their satellites go from right to left.

行星它们卫星公运动，都是从右向左。

For the first time ever, we will measurably change the orbit of a celestial body in the universe.

这是有史以来第一次我们将可测量地改变宇宙中轨道。

It was the first ocean discovered on another planet.

这是在除地球外上发现第一个海洋。

This is still so fresh that we don't actually have this object's orbit totally refined.

这对于我们仍然很新，我们实际上还没有完全确定这个轨道。

In fact, it was the first ocean ever discovered on another celestial body.

事实上，这是在除地球外上发现第一个海洋。

Astronomers detect and study dark matter by observing its effects on the visible celestial bodies around it.

文学家通过观察暗物质对周围可见影响来探测研究暗物质。

That there was a scientific way of thinking about the Heavens beyond simply saying " God did it."

运行可以用科学方式思考，而不仅仅是简单地说“这是上帝作为”。

Now, by tracking the orbits, it's possible to work out the mass of the thing at the centre.

通过跟踪这些星轨道，我们便能算出银河系中心质量。

Or perchance a celestial contrivance navigating the skies?

或者也许是空中导航装置？

This is the first-time scientists have witnessed a planet potentially being formed outside of our celestial neighborhood.

这是科学家首次目睹在我们附近之外一颗潜在行星形成过程。

So let's talk about our Mexican light show.

It's the first time humans have deliberately changed the path of a celestial object.

这是人类第一次故意改变路径。

So these had to be very bright objects.

因此必须是那些极为明亮。

But if we use infrared measurements from infrared telescopes, this allows to constrain much more the size of the object.

但如果使用红外望远镜进行红外测量，就能更精确地限定该大小。

Let's try another set of puzzle pieces from astronomical, non-black hole objects.

让我们尝试另一组来文非黑洞拼图。

The debate only intensified when objects approaching Pluto's size were discovered.

And you’d be suspended, weightless, only encountering the tiny pulls from other celestial bodies.

你会被悬空， 失重，只会遇到来其他微小拉力。

The objective of astronomy is the exploration of all phenomena outside the earth.

文学探索地球以外一切现象。

It scales with mass, so the more massive the planet or star, the stronger its gravity.

它依附于质量而存在，质量越大，它引力也就越大。
