And then, there was this image of the Carina Nebula.

这张是船底座星云的图像。

So planetary nebulae really may owe their existence to planets!

This is Hubble's first picture of the Eagle Nebula, some 6,500 light-years away.

这是哈勃拍摄的第一张老鹰星云的图，距离地球6500光年。

Gas inside a nebula can be in turmoil, too.

This time Webb showed us the Pillars of Creation from the vast Eagle Nebula.

这一次，韦伯向我们展示的鹰状星云的创造之柱。

From spectral lines, the composition of nebulae.

从谱线看，星云的组。

That's a very common shape for planetary nebulae.

这是行星状星云很常见的形状。

The color of an emission nebula depends on the gas in it and how hot it is.

发射星云的颜色取决的气体和它的温度。

But sometimes nebulae do have sharp edges.

但有时星云确实有锋利的边缘。

A cloud of agglutinated dust particles, similar to so many similar clusters in the universe.

And even I myself have seen it in  my own shot of the Orion Nebula!

我本人在猎户座星云的拍摄也亲眼见过这种现象！

In 2010 it ran out of the cryogenic coolant that enabled its primary mission of mapping the skies.

2010年低温冷却剂消耗殆尽，而低温冷却剂是绘制星云地图的必备。

The theory is that there was this cloud in the galaxy that had the same composition of the Sun.

理论上那里有银河系的星云，和太阳的分一样的。

A typical density in a gas nebula is only a few thousand atoms per cubic centimeter.

气体星云的典型密度只有每立方厘米几千个原子。

The image showed a cloud collection of 50 stars in the process of forming.

这张图片显示一个由50颗正在形的恒星组的星云集合。

He saw clusters of stars, brightly colored nebulas, even entire galaxies!

At the centre of the nebula lies the remnant of the star, its core, crushed by the force of gravity.

在星云的心处，这颗恒星的星核依然存在着，在引力的作用下它已是面目全非。

A nebula the diameter of the Earth would only have a mass of a few kilograms.
