OK, then find, the rings of Supernova 1987a, the Eskimo Nebula, the Crab Nebula, Thor's Helmut, the Carhwheel Galaxy, and the Ant Nebula.

那么找到它们：超新星1987a的环，爱斯基摩星云，蟹状星云，雷神的头盔，车轮星系，蚂蚁星云。

Why then would the gas that is streaming away create an ant-shaped nebula that is distinctly not round?

为什么气体流走时创造了一个蚂蚁形状的星云而明显不是圆形？
