Since we made this prediction , hubble and ground - based telescopes have analyzed the colors of the globular clusters in elliptical galaxies 由于我们做出了这样的预测，哈伯望远镜及其他地面望远镜因而分析了球状星团在椭圆星系里的颜色。
Interestingly , there is no evidence for massive black holes in the center of globular clusters , suggesting that these are fundamentally different from galaxies 有意思的是,球状星系中心庞大质量黑洞没有证据,暗示这些基本不同于银河系。
They usually consist of old stars . some dwarf ellipticals have as few as 10 million stars , and make them not much different from a large globular cluster 它们通常包含较年老的恒星，有些矮椭圆星系只有约一千万颗星，和大球状星团相差不远。
The roughly 200 globular clusters in our milky way galaxy contain some of the oldest known stars in the universe ; young inhabitants are nowhere to be seen 在我们的银河系里，大约有200个球状星团拥有宇宙中一些最古老的星球，不过，却一直没有发现年轻星球的踪影。
A 13 - billion year old planet orbiting a pair of long - dead stars in a crowded globular cluster : even for the hubble space telescope , that ' s amazing 在一个拥挤的球状星团中,一颗130亿年的古老星球正围绕着一对死寂多时的星星而运行,这事连见多识广的"哈勃"都惊叹不已
The evolution time in our calculation is chosen to be 12 gyr , which is the mean value of globular cluster ages in the galaxy 恒星蒸发对小质量球状星团的演化起着主导作用，大质量恒星的演化、银河系核球和盘的冲击加热以及动力学磨擦则主要影响大质量球状星团的演化。
Most models that tried to explain the origins of globular clusters focused on conditions in the early universe and assumed that the process was a thing of the past 大部份试图要解释球状星团起源的模型，都把焦点放在早期宇宙的条件，并假设此创生过程已经成为过去了。
Globular clusters are the oldest known objects in the milky way . the research of globular clusters has important significance for the study of structure and evolution of the galaxies 球状星团是银河系中最古老的天体类型之一，它的研究对理解星系的结构和演化有着重要意义。
In this nasa hubble space telescope image , the jet contrasts with the bright glow from the combined light of billions of unseen stars and the point - like globular clusters that make up this galaxy 在这张由哈勃望远镜所拍摄的照片中，我们清晰可见一串电子及一团光亮的星点组成了这个星系。
As on a crowded dance floor , the congestion in a globular cluster can cause the neutron star to move closer to its companion , or to swap partners to form an even tighter pair 如同在一个拥挤的舞厅里一样，球状星团里的壅塞局面会让中子星和它的伴星靠得更近，或者彼此交换舞伴，结合成更牢固的组合。
