星系，恒星以及行星——物理学家在在仔细思考这样的事情——它们都已经存在了，这意味着在物质与反物质之间有着一些不可思议的不对称性，自然界在某种程度上是偏爱于前者。
That galaxies, stars and planets—and physicists to ponder such things—exist therefore means there is a subtle asymmetry between matter and antimatter, and that nature somehow favours the former.
正如弗吉尼亚大学天文学教授马克·惠特尔所述，137亿年前的宇宙大爆炸爆发出与数以亿计的恒星和星系的诞生相随的巨响。
As University of Virginia astronomy professor Mark Whittle tells it, the big bang 13.7 billion years ago spawned a big noise along with billions of stars and galaxies.

The sharp image shows stunning features in the galaxy's face-on disk of stars and dust along with background galaxies, some visible right through M101 itself.
与椭圆型星系不同，漩涡型星系含有丰富的尘埃和气体，这些都是形成新的恒星的原料。
Unlike the elliptical galaxies, the spiral is rich in dust and gas for the formation of new stars.
蛇形星云，它的轮廓与聚集在我们星系中心的古老恒星逆向，约25,000光年远。
The Snake Nebula, silhouetted against ancient stars massed near the nucleus of our galaxy, which is about 25, 000 light years away.
星系与星系之间大量的气体，远比星系之间的恒星要多。

贫金属星的中子俘获元素丰度与恒星的形成和演化密切相关，它为研究星系形成早期的历史背景和化学演化提供了重要信息。
The abundances of neutron-capture elements in metal-poor stars, tightly related to the star formation and evolution, provide important clues to the chemical evolution of the Galaxy.
我们认为，是A2255中子团的并合历史导致了星系团中星系与星系之间的碰撞概率增加，从而使团中心附近的晚型星系的恒星形成活动增加了。
Compared with the merging cluster A2255, the star formation history for the late-type cluster galaxies is likely closely related to the virialization stage of parent cluster.
在观测与银河系相邻的一群微型星系时，天文学家们发现了跟上述情况同样莫名其妙的现象：不管各星系包含多少恒星，每个星系的质量都是相同的。
Astronomers have discovered something equally puzzling while surveying a group of tiny galaxies that neighbor the Milky Way: no matter how many stars they contain, every galaxy has the same mass.
事实上，NGC 2403与本星系团中的三角星系m33非常类似，它们都拥有大量的恒星诞生区。
In fact, NGC 2403 closely resembles another galaxy with an abundance of star forming regions that lies within our own local galaxy group, M33 the Triangulum galaxy.
对X射线数据的分析表明，点源与包含有中子星或黑洞(它们正从正常恒星吸走物质)的双星系统成协。
Analysis of the X-ray data shows that the point sources are associated with binary star systems that contain a neutron star or black hole that is pulling matter away from a normal star.
球状星团与疏散星团年龄相比要老得多，表明它们是在银河系形成初期形成的恒星系统。
It also shows that all globular clusters in our Galaxy are very old, much older than the oldest open clusters in the Galactic disk.
当气体集中形成恒星，所产生的喷流与爆炸会将物质向外推回星系际空间，这是一种负向的反馈机制。
As gas pools, it turns into stars, whose outflows and explosions push material back out into intergalactic space-a process of negative feedback.
