This artist's impression shows how the Arches star cluster appears from deep inside the hub of our Milky Way Galaxy. Although hidden from our direct view, the massive cluster lies 25,000 light-years away and is the densest known gathering of young stars in our galaxy. The illustration is based on infrared observations with the Hubble Space Telescope and with ground-based telescopes, which pierced our galaxy's dusty core and snapped images of the luminous cluster of about 2,000 stars.
Some of the brightest blue stars in this illustration are among the most massive stars astronomers found with the Hubble telescope, weighing about 130 times more than our Sun. The bright reddish object at upper right is the center of our galaxy, residing 100 light-years away from the Arches cluster.

这张艺术画显示了来自银河系深处的拱形星带情况。我们无法直接观察。这个密集的星带处于2万5千光年之遥，主要聚集着银河系的新星。这张图依据哈勃望远镜的红外线观察以及地面的天文望远镜的观察所绘。透过银河系的尘粒捕捉到包含2000左右星体的明亮的星带。
该图中包含在密集星体中最亮的蓝色星体是天文学家通过哈勃望远镜发现的。其质量大约有太阳的130倍。右上方的微红色明亮的星体是银河系的中心，大约距离拱形星带100光年的距离。
