说明:室女座星系团是距离我们银河系最近的星系团。
Explanation: the Virgo cluster of galaxies is the closest cluster of galaxies to our Milky Way Galaxy.
事实上,这是上镜的草帽星系的一部分,草帽星系是邻近室女座星系团内最大的星系之一。
In fact, it is part of the photogenic Sombrero Galaxy, one of the largest galaxies in the nearby Virgo Cluster of galaxies.
室女座星系团距离我们如此之近,以至于它在天空中覆盖了5度多的天区――大小约是满月的10倍。
The Virgo Cluster is so close that it spans more than 5 degrees on the sky - about 10 times the angle made by a full Moon.
而这些星系的额外的速度,不是由于宇宙的膨胀,而是由于物质在宇宙中的分布不均匀。具体地说,我们的银河系正被附近的仙女座星系和室女座星系团拉扯着。
And these additional velocities that galaxies have that aren't due to the expansion of the universe are due to the uneven distribution of matter in the universe.
