visible image
Examples
- This 11 - hour exposure image is constructed by accumulating 1 . 5 - year chandra observations , which shows a large numbers of faint x - ray sources . in particular , two x - ray emitting globular clusters near the nucleus are also visible in the hubble image . this allows us to cross - register both x - ray and optical images to determine the relative positions ten times better than before
值得注意的是，在核心附近两个发出x射线的球状星团，这两个星团哈勃太空望远镜也可观测得到，这样我们便可把相同天区的x射线及可见光影像互相比对，从而得出较以前准确十倍的相对位置。
