科学家们补充说，星系的暗物质晕可能会影响到星系自身的演化过程并决定星系的形态——椭圆状或者是涡旋状。
The behavior of a galaxy's dark matter halo could affect its evolution and help determine whether it becomes a spiral or an elliptical, they added.
许多新恒星也以螺旋系统的形式存在，但他们的圆盘由晕圈所环绕，而科学家认为晕圈富含神秘的暗物质。
Many new stars also form in spiral systems, and their disks are surrounded by a halo, which scientists believe is rich with mysterious dark matter.
研究人员们表示暗物质究竟包含什么对于他们的结果起着非常关键的作用，因为根据他们的理论，星系位于更大的球状结构——星系晕的包围之中，而星系晕是由不可见物质构成。
The researchers said the inclusion of dark matter is likely crucial to their results, because theory predicts that galaxies sit inside larger spheres, called halos, of the invisible stuff.
