One way to demonstrate a link would be to identify two populations of globular clusters in old elliptical galaxies 要证明两者彼此相关,其中一个方式,就是在古老的椭圆星系中,同时辨识出这两类球状星团。
Hubble space telescope image ? taken using only light that would be visible to the naked eye ? shows m87 [ lower right ] a giant elliptical galaxy 哈勃望远镜捕捉到的这张照片显示的是1999年1月23日伽马射线爆炸的景象。

Collisions also can transform the shape of galaxies involved; specifically, the merger of two spiral galaxies may produce a single elliptical galaxy 碰撞也会改变星系的外形,特别是当两螺旋星系融合后可能会产生单一的椭圆星系。
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。
By studying the inner regions of nine elliptical galaxies with chandra, scientists can now estimate the rate at which gas is falling toward the galaxies'supermassive black holes 科学家使用钱德拉研究了9个椭圆星系的内区,估计出了星系中心特大质量黑洞的气体下落速率。
