通向天蝎之星安达里士的黑暗之河 Connecting the Pipe Nebula to the bright star Antares is a flowing dark cloud nicknamed the Dark River. The murkiness of the Dark River is caused by absorption of background starlight by dust, although the nebula contains mostly hydrogen and molecular gas. Antares, the brightest star in the frame, is embedded in the colorful Rho Ophiuchi nebula clouds. The Dark River, pictured above across the upper left, spans over 20 times the angular diameter of the Moon and lies about 500 light years distant. Other types of nebula visible here include red emission nebula and the blue reflection nebula. 连接管状星云到明亮之星antares的是一个昵称为黑暗之河的流动暗色云状物。黑暗之河的阴暗色是由于尘埃吸收背景的星光而产生的，尽管星云含有大部分氢和分子气体。Antares，星体构建中最明亮的一颗，被嵌入五彩缤纷的蛇夫rho星云物内。穿越左上方黑暗之河，横越过20倍的月亮角直径并且延伸了约500光年的距离。此处其他可见星云包括红色散发状星云和蓝色反射状星云。

`供给船接近空间站 The crew on board the International Space Station sometimes needs supplies. As the US Space Shuttle fleet prepares to return to flight, supplies usually now come from a robot Progress supply vessel launched from Kazakhstan. Pictured above, a Progress ship approaches the ISS on May 27, delivering over 2,500 kilograms of food, water, fuel and other important items. The supply ship soon docked with the Zvezda Service Module while orbiting the Earth over 300 kilometers over central Asia. 在国际空间站上的成员有时需要补给。由于美国的太空梭船队准备返航，现在补给经常从哈萨克斯坦发射的机械助进补给船供给。这张照片，一艘飞船在五月27日接近ISS，运送超过2.5吨的食物，水，燃料和其他重要物品。当绕轨道运行地球超过300公里越过中亚后供给船很快用zvezda服务登月舱靠岸。
