| 3. | Such a device would look back at the early universe to the time when large - scale structures such as galaxies and stars formed
这样的一个装置将可以看到宇宙早期，那是大型结构例如星系和恒星形成的时候。 |
| 4. | The galaxy ' s central region is called the galactic bulge because the stars form a ball a few thousand light years in diameter that extends above and below the disk of the galaxy
星系的中心区域叫做核球，原因是恒星组成了直径几千光年的球体，膨胀到星系盘上下两侧。 |
| 5. | This breath - taking view spans about 13 degrees across the center of the well - known constellation with the great orion nebula , the closest large star forming region , just right of center
这幅动人心弦的影像涵盖了著名的猎户座中心大约13度的天区，猎户座大星云这个离最邻近的大型恒星形成区，则在影像的中右方。 |
| 6. | When my father went to school , no matter how smart he was or how smart his teachers were , nobody had a clue how old was the universe , how were atoms made , how are stars formed no one knew
当年我父亲读书的时候，不论他和的老师有多聪明，谁也说不清楚宇宙的年龄，原子是怎样产生的，星星是怎样产生的，谁也不知道。 |
| 7. | Decades of observations have established that stars form within so - called molecular clouds : vast agglomerations of cold gas and dust , each with enough material to form scores of suns
在累积了数十年的观测结果之后，一般相信恒星是在所谓的分子云中形成：在辽阔的冷气体与尘埃凝聚区域，每朵分子云都拥有足以形成许多太阳核心的材料。 |
| 8. | There are two different ideas about the massive star formation . some investigators suggest that high - mass stars form via dynamical collapse of cloud cores , resulting in disk accretion and molecular outflows , similar to their low - mass counterparts ; some peoples suggest that high - mass stars form by the coalescence of low - to intermediate - mass stars
关于大质量恒星的形成有两种观点：一种观点认为大质量恒星通过云核的塌缩，然后产生一个吸积盘和外流，即相似于低质量恒星的形成；另一种观点认为大质量恒星通过中小质量的恒星并合而成。 |
