星系

Dr. Yoshida's simulation also shows that the protostar would likely evolve into a massive star capable of synthesizing heavy elements, not just in later generations of stars, but soon after the Big Bang.

Yoshida博士的模仿也展示了原初星不仅仅在星系的后一代，而且在大爆炸很快就能够进化成巨大的星体，能够承载大重量的合成元素。

Due to the galaxy's large size, two adjacent pointings of the telescope were necessary to cover the extent of the spiral arms.

由于NGC1300的直径较大，哈勃太空望远镜必须拍摄一系列相邻的照片以拼接成一个完整的星系图像。

Star wartime generation: About 2600, as a result of a universe some galaxy eruption, the human first bitter experience diameter reaches 10 kilometers planetoids the attacks, in humanity common diligently under, finally turns danger into safety, on the Earth under the first time got up the man-made meteor shower, between the humanity here the even more unity and has been intimate, the humanity finally saw the collective wisdom and the strength, this time human complete population estimate about 2,400,000,000 people!

星战时代：公元2600年左右，由于宇宙某星系的一次爆发，人类第一次遭遇直径达10公里的小行星的袭击，在人类共同的努力下，最终化险为夷，地球上第一次下起了人造的流星雨，人类之间至此更加的团结与亲密了，人类终于看到了集体的智慧与力量了，此时人类全部人数估计在24亿人左右！

One way to find the galaxy is by finding the Great Square in the constellation Pegasus.

其中一个是利用飞马座的大四方形寻找这个星系。

In particular, a glowing knot in the outflowing stream has gotten as bright as the galaxy's star-crowded nucleus, only to dim and then brighten again.

尤其是，喷流中一个炽热的物质节暗下去又亮起来，有时甚至比挤满恒星的星系原核心还亮！

Or, are they actually normal galaxies that look like oddballs, because astronomers are getting an incomplete picture of them, seeing only the brightest pieces?

还是它们本身的样子并不怪，只是天文学家们没有把照片拍好，只弄到了星系中最亮的一部分呢？

Binary systems are not rare in a galaxy, not worthless objects either for a distant observator, for they will sometimes perform a astronomical phenomenon called occultation, that one star's radiance covers the other and makes the luminance of the whole system change regularly.

双恒星在星系内并不少见，对于遥远的观测者来说也算值得注意的对象，因为它们会发生互掩，一颗星的光芒盖过另一颗的，从而导致整体的亮度时明时暗，周期变化。

This spectacular image captures the nebulas, bright ionization fronts , and fine details of the dark dust.

这张壮观的图片捕获了这个星系、明亮的电离层，以及一些黑色的尘埃物质很多的细节。

Galactic nebulas are masses of diffuse material within our galaxy.

银河星云是我们星系中的一团团弥散物。

You can see the formation of new stars and relict light of ancient stars,"blackholes" and "supernova" stars, also nebulas, constellations and whole galaxies located far far away from us.

你可以看到，形成新的恒星和残余轻古代颗星，& blackholes &和&超新星&颗星，也nebulas ，星座和整个星系位於远离我们。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
