So over time, through collisions and crashes, the cloud loses its loft and flattens into a spinning, roughly 2 dimensional disk shape, like a solar system or a spiral galaxy.

所，随着时间的推移，通过碰撞和崩解，云失去了它垂直于旋转平面上的粒子高度变成扁平状（大概是二维的盘）旋转，像太阳或螺旋。

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.

银河是一个螺旋，太阳和太阳都是它的一部分。除此外，还有一群恒聚集在一起，形成了一个明亮的中心。

But only Hubble was able to accurately pinpoint its location — about 50,000 light-years from a nearby spiral galaxy and roughly 15,000 light-years from a smaller galaxy.

但是只有哈勃望远镜能够准确地确定它的位置——大约距离附近一个螺旋约 50000 光年，距离一个较小约 15000 光年。

Based on other galaxies we see outside of our own is why we conclude that our galaxy's spiraled as I'm shown.

通过观察其他，我了解自己之外的世界，那是为什么我断定，银河呈螺旋状。

Most spiral galaxies have disks that are a vibrant blue in color, the massive hot luminous stars dominating their emission.

大多数螺旋都有充满活力的蓝色盘，由大质量的炽热发光恒控制着它光芒的散射。

From a time near the birth of the cosmos to the rise of spiral galaxies like our own Milky Way.

从宇宙诞生的初期到像银河一样的旋状的兴起。

It also contains many bright galaxies, including the Leo Triplet, a group of three spiral galaxies.

它也包括很多发光的，包括狮子座Triplet，由三个螺旋组成的一组。

Like the Milky Way, Andromeda is a spiral galaxy, two ringed arms circling a light-filled centre.

仙女座和银河一样，也是个漩涡，它有两支旋臂，围绕着光四溢的中心旋转。

It doesn't have the beauty of a spiral galaxy or a nebula but to a scientist, to a cosmologist, it is the most beautiful picture ever taken, because it contains a vast amount of information about the very earliest history of our universe.

上面没有漂亮的螺旋，或是云什么的，但对于研究宇宙的科学家来说，这张照片意义非凡，因为它详尽地记载着宇宙最早期的样貌。

It captured these 19 spiral galaxies using near and mid-infrared technology that highlights stars and glowing dust in a level of detail astronomers have never seen before.

它利用近红外和中红外技术捕捉了这19个螺旋，突显了和发光尘埃的细节，这是天文学家前从未见过的。

Another was a spiral galaxy, sometimes called the " Hidden Galaxy, " which looks much like our home galaxy, the Milky Way.

另一个是螺旋，有时被称为“隐藏”，它看起来很像我的家乡银河。

Spiral galaxies we've seen: We live in one!

我见过螺旋的——我生活在这样一个中！

This makes them similar to the stars in the central bulges of spiral galaxies.

这使得它类似于螺旋中央凸起的恒。

The arms of spiral galaxies seem to move faster than the laws of physics would allow.

旋状的旋臂运行的速度似乎比用物理法则算出的速度快。

About half of spiral galaxies have a straight structure, called a bar, coming out from the center.

大约一半的螺旋有一个直的结构，称为棒，从中心出来。

In the 1960s and 1970s, astronomer Vera Rubin was observing spiral galaxies.

在20世纪60年代和70年代，天文学家维拉·鲁宾一直在观察螺旋。
