如果天蝎座肉眼看起来这么好，人类可能会记得更清楚。天蝎座通常是在一个众所周知但很少被指出的黄道带星座中出现的几颗明亮的恒星。然而，要获得这样壮观的图像，需要一个好的相机，黑暗的天空和一些复杂的图像处理。由此产生的数字增强图像显示出许多令人惊叹的特征。图像右侧的对角线是我们银河系平面的一部分。可见的是由明亮的恒星组成的巨大云团和由黑暗而复杂的尘埃组成的长丝。图像左侧垂直上升的是被称为暗河的黑色尘埃带。左边的几颗明亮的恒星是天蝎座头和爪子的一部分，包括明亮的心宿二。大量的红色发射星云、蓝色反射星云和暗色细丝在这17小时的世博会图像中清晰可见。在年中日落之后，天蝎座出现在南方的天空中。

If Scorpius looked this good to the unaided eye, humans might remember it better. Scorpius more typically appears as a few bright stars in a well-known but rarely pointed out zodiacal constellation. To get a spectacular image like this, though, one needs a good camera, a dark sky, and some sophisticated image processing. The resulting digitally-enhanced image shows many breathtaking features. Diagonal across the image right is part of the plane of our Milky Way Galaxy. Visible there are vast clouds of bright stars and long filaments of dark and intricate dust. Rising vertically on the image left are dark dust bands known as the Dark River. Several of the bright stars on the left are part of Scorpius' head and claws, and include the bright star Antares. Numerous red emission nebulas, blue reflection nebulas, and dark filaments became visible as the deep 17-hour expo image developed. Scorpius appears prominently in southern skies after sunset during the middle of the year.
