What you're looking at is thousands of light years away, it's a planetary nebula, a giant cloud of gas that forms around an ancient star that hasn't yet exploded.

你正在看是数千光年以外一团行星状星云，是在尚未爆炸古老恒星周围形大气体云。

Spirals fascinated Smithson, and in his writings, he also mentioned their occurrence in galaxies and nebulae, in the structure of crystals, in the human ear, and in particular in Constantin Brancusi's famous portrait of James Joyce.

史密森对螺旋很着迷，在他著作中，他也提到了在星系和星云中出现，在晶体结构中出现，在人耳中出现，特别是在康斯坦丁·布朗库西对詹姆斯·乔伊斯著名肖像中。

However, this nebula started off more or less as a big shapeless blob.

但是一开始这星云或多或少更像个不形水滴。

On Monday, new images were released showing thousands of never seen before stars and this image of a newborn star from the Orion nebula.

星期一，一组新公布照片展现了数千颗前所未见恒星，这张照片是户座星云一颗新生恒星。

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

他看到了无数星团，明亮星云，甚至还看到了整个银河！

Those older telescopes had to focus on nebulae, where the interstellar gas is most concentrated (a familiar one, visible through binoculars, is the gas cloud around the stars that make up Orion's sword).

以往望远镜必须关注星云，那里是星际气体最集中之处。一个可用双筒望远镜看到典例是气体环绕恒星所形户座”剑”。

If scientists had to read or write them out in full when they were discussing things like the molecules of water in a swimming pool or the distance to the Orion nebula, it would take up pages of books.

如果科学家在讨论游泳池里水分子或距离户座星云距离等问题时，必须完整地全部读出来或写出来，就会占用好几页书。

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.

上面没有漂亮螺旋星系，或是星云什么，但对于研究宇宙科学家来说，这张照片意义非凡，因为详尽地记载着宇宙最早期样貌。

Without them there would be no water or air or rocks, no stars and planets, no distant gassy clouds or swirling nebulae or any of the other things that make the universe so usefully material.

没有原子，就没有水，就没有空气，就没有岩石，就没有恒星和行星，就没有远方云团，就没有旋转星云，就没有使宇宙如此动人、如此具体任何别东西。

It began with Professor Stephen Hawking describing the mysteries of the universe, then, in a burst of fireworks, the stadium was transformed into a nebula of gases in deep space – the big bang coming to Stratford.

开幕式一开始，史蒂芬·霍金讲述了宇宙神秘，一阵烟火点燃后，整个场馆变外太空星云，宇宙大爆炸来到斯特拉特福。

While EMISSION nebulae glow due to their own light, REFLECTION nebulae are bright because — can you guess? — they reflect the light of nearby bright massive stars.

发射星云由于自身光线而发光，而反射星云之所以明亮，是因为——你能猜到吗？——反射了附近明亮大质量恒星光。

If the sky is dark enough, you can see the nebula with just your eyes—but you can get a better look with binoculars or a telescope.

如果天空够暗，肉眼就能看到星云，不过用双筒镜或望远镜可以看更清楚。

It's a presence that surrounds us always, from beginning to end, like a golden nebula looming over our lives even in the most mundane moments.

是自始至终都环绕在我身边现实，像金色星云萦绕天空，即使在最平凡日子里也熠熠生辉。

In the night sky, plasma gives out light in the form of stars, nebulas, and even the auroras above the north and south poles.

在夜空中，等离子体以恒星、星云甚至北极和南极上方极光形式发出光。

This swirling mass or " nebula" began to cool and, as it did, it condensed and separated into rings of particles.

这个大旋涡状物质或" 星云" 开始冷却，而且，随着冷却开始聚集，并分开变粒子环。

It is a nebula: a star-forming region where new stars are being born.

一个正在诞生新恒星恒星形区域。

Among the other four images were two that showed huge clouds of gas and dust – called nebulas.

在其他四张照片中，有两张展示了大气体和尘埃云——也就是星云。

The orion nebula is a special kind of nebula called a stellar nursery.

户座星云是一种特殊星云，叫做恒星摇篮。

Because when we look deep into the nebula, we don't just see individual elements.

因为当我凝视星云时，我看到并不是单一化学元素。
