车轮星系

A spectacular head-on collision between two galaxies is seen in this NASA Hubble Space Telescope true-color image of the Cartwheel Galaxy.

车轮星系(Cartwheel Galaxy, ESO 350-40)是一个位于玉夫座的透镜状星系,距离地球五亿光年,其直径大约15万光年。

这个星系的样子呈车轮般光环状,外部的光环是不少新形成的恒星。天文学家认为,这个星系原本是一个像银河系般的螺旋星系,因为与另一星系相撞,才变成今天的车轮状。他们估计在约两亿年以前,一个较小的星系撞向较大星系的中央。由于较大星系中心的重力遭小星系扭曲,以致产生冲击波,从中央冲向外部,使外层星云受压,形成新恒星。虽然人们找到车轮星系旁边有两个小星系,但多认为与它们与这次碰撞无关,原来发生碰撞的星系早已离去,现估计位于距离25万光年的位置。
