- BRAD GIBSON and RODRIGO IBATA started working together in 1997 to use observations of the Sagittarius dwarf elliptical galaxy to understand dark matter. 吉布森与伊贝塔自1997年起合作，利用人马座矮椭圆星系的观测资料来理解暗物质。
- Observations by Hubble’s Advanced Camera for Surveys spotted 29 dwarf elliptical galaxies in the Perseus Cluster located 250 million light-years away and one of the closest galaxy clusters to Earth. 哈勃使用先进的观测镜头对英仙座中29个椭圆状矮星系进行了观察，这些星系属于距离地球最近的星系团之一，约2.;5亿光年远。
- dwarf elliptical galaxy 矮椭圆星系
- A major merger wipes out the disk and leaves an elliptical galaxy in its place. 一个大型的并吞将会破坏星盘，而在原处留下一个椭圆星系。
- If the Earth were inside an elliptical galaxy it would be bright both day and night. 如果地球是一个椭圆形的星系内，将是光明的两个白天和黑夜。
- The stars in an elliptical galaxy are often very close together making the center look like one giant star. 该星在椭圆星系往往是非常密切的合作使中心看起来像一个巨大的恒星。
- The best-known shape-shifting process is galactic cannibalism: merging with a neighbor can turn an orderly spiral into a messy, beehivelike elliptical galaxy. 最有名的形状变化过程是星系间的同类相残：并吞旁邻的结果，可将一个原本井然有序的螺旋星系，转变成一个拥挤杂乱的椭圆星系。
- This is particularly unusual as Cen A's red stars and round shape are characteristic of a giant elliptical galaxy, a galaxy type usually low in dark dust. 这是一个非常不寻常的特征，因为半人马座A的红色恒星和浑圆的外观，显示它是一个巨大的椭圆星系，而这种星系的尘埃含量通常很低。
- Though the details are still not clear, it seems that the growth of the black hole is intimately related to the growth of the spheroidal component- an elliptical galaxy, or the bulge of a spiral galaxy- in which it lives. 虽然细节仍然不清晰,好象黑洞生长与类星体生长密切有关-一个椭圆的星系,或螺旋形的星系-它在里面的星系凸起。
- If stars are born in the gas before the galactic cloud becomes rotationally supported, the stars will maintain their individual orbits around the galactic center, creating an elliptical galaxy. 如果恒星在气体中的诞生比星系云变为旋转性支撑早，那麽恒星将会各自保持其绕转星系中心的轨道，因而形成椭圆星系。
- This is because elliptical galaxies don't actively create new stars. 这是因为椭圆星系并不积极创造新的恒星。
- Billows of cosmic dust swirl amid NGC 1316, a giant elliptical galaxy formed billions of years ago when two spiral galaxies merged. 几十亿年之前,两个漩涡星系合并成一个椭圆星系NGC 1316,宇宙尘埃在它的内部翻滚。
- At first glance, it looks as if a smaller galaxy has been caught in a tug-of-war between a Sumo-wrestler pair of elliptical galaxies. 乍一看,它像一个较小的星系已经被一个双椭圆星系像拔河一样被撕裂开。
- Although many elliptical galaxies are in clusters of galaxies, NGC 1132 appears as a large, isolated galaxy toward the constellation of the River (Eridanus). 虽然有许多椭圆星系是存在于星系团之中，但位于波江座的 NGC 1132 似乎是一个巨大的孤立星系。
- If elliptical galaxies and spiral bulges are linked to galaxy mergers, then it follows that supermassive black holes may be created in these events, too. 如果椭圆星系及螺旋核球与星系合并有关，则或许超大质量黑洞也是从合并中产生的。
- Spiral galaxies contain both young and old stars. In general, they are brighter than elliptical galaxies. 旋涡星系同时拥有年老和年青的恒星,它们通常比椭圆星系光。
- 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。
- There is a dwarf apple tree in our garden. 在我们的花园里有一棵矮苹果树。
- Bulges and elliptical galaxies (that is, diskless bulges) form when galaxies collide and merge. 当星系碰撞合并时形成了椭圆星系。
- Astronomers may be directly observing, for the first time, the formation of elliptical galaxies. 或许这就是第一次，天文学家可以直接看到椭圆星系的形成。
