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

这张是船底座图像。

So planetary nebulae really may owe their existence to planets!

所以行状存在可能真要归功于行！

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

Gas inside a nebula can be in turmoil, too.

内气体也可能处于混乱状态。

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

这一次，韦伯向我们展示了巨大鹰状中创造之柱。

From spectral lines, the composition of nebulae.

从谱线看，组。

That's a very common shape for planetary nebulae.

这是行状很常见形状。

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

发射颜色取决于其中气体和它温度。

But sometimes nebulae do have sharp edges.

但有时确实有锋利边缘。

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!

我本人在猎户座拍摄中也亲眼见过这种现！

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

2010年其低温冷却剂消耗殆尽，而低温冷却剂是其绘制地图必备。

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，和太阳分一样。

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

气体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.

这张图片显示了一个由50颗正在形恒组集合。

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