星云的

With more mass than the Sun and the density of an atomic nucleus, the spinning pulsar is the collapsed core of a massive star that exploded, while the nebula is the expanding remnant of the star's outer layers.

中心的脉冲星是由大质量恒星塌缩形成的，它的质量比太阳要大而密度和原子核差不多，而星云则是由恒星外层膨胀所形成的。

The high-energy radiation blazing out from clusters of hot young stars is slowly eroding nebula, and another young cluster may be hidden beneath the circle of brilliant blue gas.

高能量辐射的创新，从集群的热点年轻恒星正慢慢侵蚀星云，和另一名年轻群集可能是隐藏下方的圈子，亮蓝的气体。

Located about 6,500 light-years from Earth, the Crab Nebula is the remnant of a star that began its life with about 10 times the mass of our sun.

远离地球6，500光年远的蟹状星云是一颗10倍于我们的太阳重量的星的残余。

Explanation: This is the mess that is left when a star explodes. The Crab Nebula, the result of a supernova seen in 1054 AD, is filled with mysterious filaments.

蟹状星云是恒星爆炸后留下的痕迹，是公元1054年所见的超新星爆发的结果，它充满了神密的纤维状细丝结构。

"A celestial cyclone, a pulsar at the heart of the Crab Nebula fires off jets of high-energy particles in this Chandra image."

在这幅由钱德拉（NASA的轨道X射线天文台）所发回的照片中，处在蟹状星云中心的一颗脉冲星正发射出一股高能量的粒子形成了天体飓风。

When you close to them,you will find they are far away,they are apart.Over the way,light-year.

但是在你跨越所有的距离，以更近的距离去看那些星云时，你会发现，他们是如此地遥远，甚至超过了你用光年的距离看他们的距离。

At the edge of a large molecular cloud in Monoceros, some 5,000 light years away, the petals of this rose are actually a stellar nursery whose lovely, symmetric shape is sculpted by the winds and radiation from its central cluster of hot young stars.

星云位于麒麟座巨大分子云的边缘，距离我们大约5，000光年远，而玫瑰的花瓣实际上就是一个恒星孕育场，而其可爱而对称的形状是由于中央年轻炽热恒星团发出的恒星风和放射线侵蚀而成。

J. Moffat, all from CRAQ (Centre de recherche en astrophysique du Québec), a center belonging to the University of Montreal in Canada, have broken that record twice.

星云中所有的恒星几乎有相同的年龄，即100万年，但这与我们有50亿年寿命的太阳和太阳系相比，只是一眨眼的时间。

This famous object is a so-called planetary nebula that represents a phase of stellar evolution that the Sun should experience several billion years from now.

这个著名的天体之所以被叫做行星状星云是因为其代表了一个行星进化的阶段，就好比太阳形成至今几十亿年间所经历过的。

To better understand this complex and chaotic process, astronomers used the Hubble Space Telescope to image in unprecedented detail the star forming region LH 95 in the nearby Large Magellanic Cloud galaxy.

为了更好地了解这个复杂而又混乱的过程，天文学家利用哈勃太空望远镜对大麦哲伦星云附近的恒星形成区域LH95拍摄了空前详细的影像。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
