Seen nearly edge-on, NGC 253 is only 13 million light-years away, the largest member of the Sculptor Group of galaxies, neighbor to our own local galaxy group.
在靠近天穹边缘出现的 NGC 253 距离我们只有 1300 万光年之遥,它是玉夫星系团的最大的成员,和我们所在的星系团相邻。
That makes it at least equal in size to the largest galaxy in our local group, the Andromeda Galaxy.
