大约1.9亿光年远，在银河系明亮的恒星和星云之外，这三个星系被引力吸引在一起，上演了一场迷人的宇宙之舞。由于星系尺度的引力相互作用，大的螺旋星系NGC6769和NGC6770被明显地扭曲了，明亮的星系盘被模糊的星际尘埃带弄得伤痕累累。它们年轻的蓝色星团沿着被拉长的旋臂在恒星形成区域产生，这些区域是由大质量分子云的碰撞产生的。下面，螺旋NGC6771呈现了一个更侧面的视角，它的四方形中央凸起是由于潮汐恒星流。当然，在遥远的未来，三个星系的合并是不可避免的。在这个被一些人称为“魔鬼面具”的三星系的估计距离上，这个锐利的望远镜框架在遥远的南方星座Pavo的边界上跨越了30万光年。

Some 190 million light-years away, far beyond the bright stars and nebulae of the Milky Way, these three galaxies are drawn together by gravity in a mesmerizing cosmic dance. Clearly distorted by galactic-scale gravitational interactions, large spiral galaxies NGC6769 and NGC6770 are seen face-on, with luminous galactic disks scarred by obscuring interstellar dust lanes. Their young blue star clusters along drawn out spiral arms are spawned in star forming regions that result from collisions of massive molecular clouds. Below, spiral NGC6771 presents a more edge-on perspective, its boxy central bulge due to tidal star streams. Of course, in the distant future a merger of the three galaxies is inevitable. At the estimated distance of this galaxy trio, known to some as the Devil's Mask, the sharp telescopic frame spans over 300 thousand light-years within the boundaries of the far southern constellation Pavo.
